The restrooms in the North end of the Law Center promenade are marked "male" and "female". There is no law in Oregon about how to assign gender identity. The restrooms nearer the lecture hall are marked "Urinals and Stalls" and "Only Stalls".

The restrooms on the first floor of Fenton Hall are marked "male" (only one toilet) and "female" (two stalls). There are also single-use, all gender restrooms on the second floor. Across 13th street from Fenton, Tykeson Hall has multiple-use restrooms. So, if you want to use the restroom during the lecture, you should use the ones down the hall to the North, but during the break, it may be more convenient to go out the South door, across the street and use those. They are not separated by gender.

On Monday, June 20, campus will observe the Juneteeth Holiday. The Law Center will be locked, but we will let you in. However, please be on time, since we will be going into the lecture at 9am, and there will not be anyone else in the building to let you in.

On Saturday, June 25, instead of entering the Law Center through the main entrance, which will be locked, you will have to enter the South door nearest the lecture hall.

On Saturday, July 2, to enter Fenton, the main entrance will be locked so, you will have to enter the South door nearest the lecture hall. The main entrance of Fenton is inconvient to access the lecture hall normally, since it requires stairs and the south door doesn't.

For the Participant Talks in Deschutes Hall, the building is locked at 5PM. I will let you in, but please be prompt, because when the talks begin at 8PM, I will be required in the hall on second floor.

Installed Software

Some speakers ask that you be prepared to run software along with them, or as exercises outside of the lectures. (See Steve Zdancewic and Thorsten Altenkirch) It is recommended you do that prior to OPLSS and test it out in case there are problems with your installation.

Meals

The cafeteria menu is posted online. Your room and board plan includes breakfast (7AM-9AM), lunch (NOON-2PM) and dinner (5PM-8PM). (The webpage may suggest other meals, because it is set-up for the academic year, which is different.) I will try to predict other groups using the cafeteria at the same time as us, and make announcements at lecture. In general, the youth athletic camps break for lunch at noon and resume at 1PM, so normally, you will do better to go to lunch at 12:45 or so. Similarly, the kids are hungry after physical activities, so they tend to eat dinner early. It is better to eat dinner at 6PM or 7PM, like a normal person.

Inter-Cultural Communication

For non-Americans, asking simple directions can be tricky. The points of reference that are valid in European cities are not the same in American cities. It is always better to ask me, or someone from Eugene, a specific question than a general one. For example, one year, a European woman said that Eugene natives act friendly, but they are really duplicitous. "How so?" I asked. "Well, every time I ask directions to downtown, they tell me how to get to the library." "Take the EMX to Eugene Station" "I don't want to go to the library. I want to go downtown." "Downtown is the library and the bus station and maybe Voodoo Doughnuts." "I want to go to the section of town with lots of dancing." "Well, you'll never find that downtown." She should have asked directions to Taylor's rather than directions to the library, because her cultural reference to "downtown" is not the Eugene understanding of the term, but if she knew about Taylor's, she would probably not have to ask how to get there. Thus, it would be better to just say what you want, as in "I want to go dancing," and we will cheerfully tell you where to go.

Climate

Oregon is not a humid climate. If you are from the US interior Southwest, you may find it a bit humid, but if you are from anywhere East of the Rocky Mountains in the US, or some foreign places, you will find it very dry. This means that at night, there is a 30F or more drop in temperature. Because the usual school year runs from October to May, the dorms have heating, but no air conditioning. I usually get requests for extra blankets, which I can accommodate. The typical pattern in Oregon is to open the windows when the sun goes down, but keep them closed in the heat of the day. (see the April 26 aside about hay fever)

While you are in Eugene, the weather will be hot, and the river will be cool, but don't go jumping into the river. The rivers here are fed by snow melt in the surrounding mountains. Therefore, the water is barely above freezing. People occasionally jump into the river to cool off, and their bodies are recovered downstream. Wading is refreshing, but do not jump into the water all of a sudden without acclamation.

Alcohol

There is no drinking alcohol allowed in public areas in Oregon (and specifically on the University of Oregon campus) unless you have OLCC licensed servers controlling access. Specifically, this means that you can drink in your dorm room, if the door is closed and the people in your room are all 21 years or older, (Supplying alcohol to people under 21 is illegal.) but you cannot drink in the public areas of the dorm. — One year, OPLSS participants had the idea to put beer bottles in the ice machine, and the 10 year olds in the building were stealing the beer to take to their rooms and drink. If you want to drink with the other participants, you should go with us on our walks.

Marijuana

Similarly, there is no smoking marijuana in public or supplying it to minors in any form. See section below for limitations on smoking, which include marijuana. Eugene's marijuana shops offer a large variety of edible products.

Smoking

Oregon cities are largely non-smoking. Smoking includes tabacco, clove cigarettes, marajuana, and anything else that causes people in your vicinity to partake in the drug you are inhaling.

In Oregon, it is illegal to smoke inside a public building or within 20 feet of any building entrance, or on State owned lands, such as a beach or wilderness area. The city of Eugene does not allow smoking in city-owned places, such as parks or transit facilities. The University of Oregon is a Smoke and Tobacco Free University, which includes prohibiting vaping or smoking marijuana in your dorm room. Smoking by OPLSS participants who are not UO students results in a $30 fine. If you are staying at a hotel, it is probably smoke-free — ask the hotel. This means that you will be hard pressed to find anywhere to smoke conveniently. You can stand in the middle of some streets, waterways and railroad tracks on campus, and while it is not technically illegal to smoke there, it is strongly discouraged for safety reasons, and casual littering like leaving a cigarette butt in the street is illegal. In most places in Eugene, smoking does not include ecigs, but University of Oregon policy considers them a prohibited tobacco product. Chewing tabacco is similarly prohibited by the University, but not the city or the state; however, most restaurants, bars and taverns will not allow chewing tobacco, and spitting chewing tobacco in the street is the kind of casual littering that is illegal in Oregon.

Therefore, if you are addicted to nicotine, in addition to the items listed on May 10, you should plan on bringing nicotine gum or patches, or you can obtain them here.

Access to computing resources on campus is governed by applicable US laws. In particular, US law says that sharing copyrighted content over the Internet is illegal, and the copyright holder is entitled to huge damages from the perpetrator and anyone who allowed it to happen. Therefore, the University of Oregon has incentives to disable your access if you are doing something illegal. For whatever logistic reason, it is better/easier for them to forbid your MAC address accessing resources than disabling your credentials.

Health Care

In the US, if you need urgent assistance call 911. The emergency operator can connect you with emergency medical service providers, the fire department or the police in any jurisdiction in the US. This should work on cell phones. For non-threatening situations, you can use University Oregon emergency contacts.

If you need health care for non-life threatening conditions, you should go to Nova Urgent Care which is west along 13th street past the end of campus, three blocks to Patterson. It is on the SW corner. It is open 8AM to 8PM every day. You should expect to pay a hundred or more dollars if you do not have insurance.

If you need major medical treatment, you should go to the Emergency Room at PeaceHealth, Sacred Heart, University District campus which is west along 13th street past the other end of campus, two blocks to Hillyard. It is on the NE corner. It is always open. You should expect to pay several thousand dollars if you do not have insurance. If you have to be transported by ambulance, that will be several thousand dollars more.

The Emergency Room at Sacred Heart can treat everything that Nova Health can treat, but at much higher cost. Even if you have insurance that covers medical expenses, emergency room care can be very confusing if you are not used to American health care. After a trip to the emergency room, you can expect between five and ten separate bills from separate entities: the hospital itself, and every person who treated you, or consulted in your treatment, some of whom you may not have met. US law says that Sacred Heart must treat you and determine costs and payment later. Nova Health, on the other hand, will tell you all the costs, but will either expect you to provide your insurance information, or pay before receiving treatment.

If you are from another industrialized country, you will find the US Health Care system is much more expensive and not as good as what you expect (unless you are having a heart attack), but this is where you are, so you need to use what is available in an emergency. If you are not living in the US, you should obtain prior paperwork from your country to cover medical expenses while in the US.

Small Appliances

The April 26th entry says to bring a laptop and adapter to US electrical outlets, if needed. Of course, other small appliances will also need an adapter. The dorm does not have hair dryers or irons. I think of these as "personal grooming items," (see April 26). Hot plates and other cooking appliances are not allowed in your dorm room.

Participant Talks

The information on participant talks is on the schedule page You should let me know if you want to give a talk. The point is to get other participants interested in collaborating with you in the future. A talk should consist of a short presentation of your research followed by an off-the-cuff dialog with the audience. If you want to give a talk, you should send me a title and abstract that describes your research. This is good practice for giving talks to an audience of critics as well as your peers.

We are staying in the Living Learning Center. I have updated the check-in and check-out sections of the travel information page. Your check-in instructions will vary depending on what time you will arrive.

If you are thinking of driving a car to OPLSS, or renting a car when you get here, think again. The University of Oregon's general policy on driving to campus is "Who told you to do that?" During the school year, I would definitely tell you not to bring a car. During the summer, you may be able to find parking; however, on July 1st the overnight parking is mostly being taken over by the World Athletic Championships and it will become very difficult to find a spot to park for the night. If you insist on having a car, you can obtain a visitor parking permit from the UO Transportation Office . The "permit" is a virtual permit that allows a car with your license plate to park, and must be purchased each day ($18).

The local hospital and the university have a bike share service. You can visit their website and set up an account. The rental bikes are distributed around Eugene, and you rent one by walking up to it and scanning the QR code with your phone. The bike will unlock for you. Your account is charged for the time you spend riding it until you lock it up again at your destination. The bikes do not come with a helmet, so please bring your own.

Points of interest on the map:

If you have a housing package, the meals will be served at the Cafeteria. The hours are:
  • Breakfast 7:00 AM - 10:00 AM
  • Lunch 11:00 AM - 2:00 PM
  • Dinner 5:00 PM - 8:00 PM
If you are not staying in the OPLSS housing, you can pay at the cafeteria door and eat with the other participants.
Some common concerns:
Food Allergies
The menu (hours will change during summer) and the item labels in the serving area contain markings for problematic food ingredients, including milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans and sesame seeds.
Vegetarian/Vegan/Raw Foodist
If you are vegan or vegetarian, there should be no problem finding adequate hot and cold food in the cafeteria. If you are raw foodist, there is an extensive salad bar. There is also a large selection of fresh and once frozen fruit, although some frozen fruits may have been blanched (heated briefly) before being frozen.
Halal
I do not know of any halal butchers in Eugene, and the cafeteria does not order halal meat. In general, my Muslim friends find plenty to eat at the cafeteria, by sticking to the vegetarian offerings.
Kosher
Kosher is tricky. This surprised me since I know many Jews in town. Talking to my friends and the Jewish Student Union and Hillel and several Rabbis, it seems to come down to "if you live in Eugene, you have to make compromises." It is certainly possible to observe a Jewish-American, not-very-strict, kind-of-kosher, by abstaining from certain foods. In the cafeteria, asking "Is it kosher" is probably not as good an idea as asking for the ingredients, which the chef will be happy to share with you. Anyway, the answer to "Is it kosher?" is always no, since the cooking utensils and serving vessels are not kosher.
Jhatka
Since the meat in the cafeteria is neither expressly halal nor kosher, it is unlikely to be Kutha, but American butchery practice is not guaranteed to be strictly Jhatka either. While chickens are often killed with much suffering, cows and pigs can suffer as a result of unintentional mechanical failures. If you have strong ethical beliefs, you might want stick to the vegetarian options.
Free-Roam/Cage-Free Livestock
Since US law does not specify what it means to raise livestock cage-free, and the University does not have resources to investigate the source of animal products past the USDA oversight at the packing plant, asking for cage-free animal products would just be an invitation for suppliers to lie. Therefore, the dining hall cannot certify that any animal products were or were not produced in cage-free environments.

The housing packages with OPLSS begin with check-in at 4PM on Sunday, June 19. Your first meal is dinner that day from 5-7:30PM. You can arrive any time that day. I will be on campus at 10AM and you can drop your luggage off at my office. (full instructions on the Travel Information page, Check-In section.) After the housing office closes at 8PM, you can get your keys by calling the number on the door. I will post that number here, when I get it. Flights arriving anytime between 8AM Sunday to 2AM Monday are pretty normal for OPLSS.

The housing packages with OPLSS end with check-out before Noon on Sunday, July 3. Your last meal is lunch at 11AM on Sunday. People sometimes book flights that leave during the last lecture on Saturday. I would suggest not doing this if you can avoid it. If your flight leaves later than 2 or 3PM on Sunday, I let you into the department lab with your luggage, where you can work in an air-conditioned environment. If your flight leaves later than 8PM Sunday, however, you will have to arrange a motel room, or a stay at the Eugene Hostel.

During OPLSS, you can use the UO guest wireless network or the eduroam wireless network. To use eduroam, your institution must be a member. Please consult your campus network administrator before arriving at OPLSS.

UO guest and eduroam will work well in your dorm or on other places on campus; however, the classroom is configured to have fewer than a dozen guests and fewer than a dozen eduroam users when classes are in session. So, you will have limited bandwidth. I suggest you take the following steps:

  • During lectures, use only text-based services on your laptop.
  • Download any software used by the lecturer before attending the lecture. Details of software used in the lectures are contained on the topics page under the entry for each lecturer.
If you have a housing package for a shared room, and you know who you want as a roommate, please let me know by May 17th. I would encourage you not to do this. One of the purposes of OPLSS is to meet people in the field. When putting together the room roster, I try to put Americans with non-Americans, East Coast people with West Coast people, etc, to make sure that you are meeting people you would not otherwise know. If you ask me to put you in a room with your lab partner, I will do that, but you are missing out on part of the point of OPLSS. You already talk about PL research with your lab partner; this should be an opportunity to talk about PL research with someone else. Also, I tend to put people from the same school in adjacent rooms, so it's not like you won't see the people you know.
Happy May Day!

Oregon was the first US state to create a day honoring labor, although it was in June. There are links on the Venue page about the other great May Day tradition: Morris Dancing.

If you want your nametag to indicate your pronouns, please email me with the information.

Pronouns commonly used in Oregon

  • He, him, his
  • She, her, hers
  • They, them, their
  • Ze, hir, hirs
  • Co, co, cos
  • Per, per, pers

To be clear: Housing is arranged through me. Going to the credit card website and paying for some kind of housing does not guarentee that kind of housing is available. Not everyone pays by credit card, so there is no connection between the credit card payment site and housing reservations. You have housing reserved for you when I tell you I have reserved housing for you. Similarly, not paying for housing does not cancel the housing I have reserved for you. Telling me to cancel your housing will cancel your housing.

The website says you must pay your registration by the middle of May to hold your place at OPLSS. The website also says you must arrange or cancel your housing by the middle of May. This means that you do not have to pay your housing until you arrive, but you will be liable for the cost if you do not tell me to cancel by the middle of May.

Sometimes, through the machinations of arithmetic, it may not be possible to pay your housing through the credit card website. In that case, you will have to use one of the other methods of payment listed on the rates page.

If you applied, with any required recommendations, before today, and were accepted, you should have already received an acceptance letter, suitable for obtaining a visa to the US, and an invoice. Please have the letter with you when crossing the border into the US. If you have not received both of these, please let me know so I can see what happened to your application.

Please don't pay for things that don't appear on your invoice! If you want to change your accomodations, please email me and I will send you a corrected invoice which you can pay. It looks very bad to auditors if you pay more money than your invoice shows. If you have extra money lying around, book a trip to Trinidad and Tobago, but do not send it to me unless I have sent you an invoice that indicates that amount on the "total due" line.

Things to bring to the summer school:
  • A laptop
  • Soap, shampoo and other personal grooming items.
  • Typically, I tell everyone to bring allergy medication. The main agricultural products in the Willamette Valley are grass seed and mint, so if you are allergic to grass pollen, expect to feel the effects while you are here. Typically, the grass pollen count is worst in June, with the level tapering off as summer progresses. Some students travelling to OPLSS experience pollen allergies for the first time. You can see a complete pollen report at www.weather.com, zip code: 97403 (pay attention to the grass number). Pseudofed is a prescription drug in Oregon, so if you intend to purchase it here, either bring a prescription, or use one of the better, non-prescription alternatives.
  • You should not bring pillows, blankets or towels (see April 25 entry)

Acceptance has been established for people who applied and received a recommendation before April 15 and grant funding has been allocated.

By default, I assume you want a shared room in the dorm. Based on capacity, we have a very limited number of single rooms available. You should let me know if you want a single room. Please let me know if you have mobility problems, although the dorm has an elevator, and the lecture hall is wheelchair accessible on the first floor.

This year, we will be in the Living Learning Center. The room layout for the dorm is Living Learning Center Double. (You have to scroll down.) I suggest you not bring your own sheets and towels since housekeeping will probably throw them in with everyone's linen when they change your room linens. In the past, this has lead to much consternation, especially if your linens are white, or slightly off-white as you look through the campus collection of laundry trying to find your sheets. If you do need to bring your own sheets, I suggest you put a sign on your door asking that your linens not be laundered. Also, talk to me so I will talk to the housekeeping staff.

I thought this would be obvious: the dorms have laundry facilities . For the past 20 years, a load of laundry is $0.75 and dryers are free, but Housing is negotiating with the laundry vendor right now, so it is possible it will change. The laundry room does not vend little packets of soap, but there is a supermarket four blocks away. I suggest you pool together with other participants needing landry soap or bring some with you.

In the past, very few participants have chosen to stay elsewhere during OPLSS. The dorms are not deluxe accommodations, but there is usually lots of discussion that goes on in the dorm, and participants who stay off-campus have felt isolated from this. However, if you want a hotel room near campus, here are a few options that are within 5 blocks of the lecture hall.

While here, it is possible to use the Student Recreation Center (location) with a Daily Pass. The Student Recreation Center is across the street from the OPLSS dorm. If you want to obtain a pass for more than one use, you must also obtain a UO community card from University of Oregon Card Services. (location) They require that once you are on campus, you send an email to uocard@uoregon.edu with

  • You are requesting a "Community Card" and when you expect to pick it up
  • Your name
  • A picture of your face; you should not be wearing a hat or any other ornamentation that would obscure your appearance; the picture should be of you looking directly at the camera
  • A picture of a government issued identification of you; for US citizens, this is usually a state drivers license; for non-US paricipants, this is usually your passport
Your community card costs $10 and can be picked up on campus from the first floor of the building immediately to the Northwest of your dorm along the footpath. I (and the Card Office) suggest you visit the Student Recreation Center once to see if you like the facilities/summer hours. For further access, you can obtain a community card and a Recreation Center Pass.

There are many outdoor activities to do in Eugene. Within a 30 minute walk from the dorms are

Here is what should happen if you submit a Registration:
  • A webpage should show your registration was accepted and the details you just submitted. Please check the email address to make sure it is correct. If you submit a registration with a typo in the email address, I have no way to reach you. If you did make a typo in the email field, you should immediately email summerschool@cs.uoregon.edu with the correction.
  • You should receive an email confirmation of your registration.
  • If you are applying for a grant, when we receive the required letter of recommendation, you will receive an email acknowledging the letter has been received.
  • After the April 10 deadline, you will receive an email indicating your acceptance into the program. At that time, I will give you options for housing. You will only need to respond if you do not want me to reserve a shared room in the dormitory. When I have notified everyone of their acceptance, I will post a note on this website that I have done so. If you did not get an email from me, you should send an email to summerschool@cs.uoregon.edu asking about your status, as I have probably misplaced your application.
  • If you are applying for a grant, it takes us longer to decide how the grant money is allocated. At some point, you will receive another email stating your grant status. When I have notified everyone of their grant status, I will post a note on this website that I have done so. If you did not get an email from me, you should send an email to summerschool@cs.uoregon.edu asking about your grant status, as I have probably misplaced your grant application.
  • Sometime before May 16, you will need to pay your (non-refundable) registration and tell me whether you want a dormitory room. You do not need to pay for your room and board at that time, but I must tell the housing authority how many rooms we will require.
You should see as you arrange travel, that it is usually much cheaper to fly to Portland and then take a train to Eugene. The cost of a train from Portland to Eugene (about $25) is approximately the same as the cost of a taxi from the Eugene airport to campus. If you are sharing the taxi, of course it will be cheaper for you, but you should find that although it takes a few extra hours to fly to Portland and take a train down, it will save you money. In particular, booking flights directly from Eugene after OPLSS may be costly and/or quickly sold out because of the upcoming 2022 World Athletics Championships in Eugene.

By the way, track and field officionados at OPLSS often ask if they can run on Hayward Field. Usually, the answer is yes because it is open to the public when not in use, but with OPLSS being so close to the World Athletics Championships, sadly the answer may be no this year. However, many running paths are available near campus. Pre's Trail ( Steve Prefontain is a local hero) is a short walk across the river.

I added a field to the registration form to allow you to tell me any logistic data I need to know. Only I will see the contents of the field; it will not be used to assess your preparedness to attend OPLSS. What I intend is that before your arival, either on the registration form, or in email, you will tell me things like "I have mobility problems," "I need to bring my seeing eye dog," "I need a medical exemption to COVID mask requirements" (If COVID masking is in place for the university at that time, a medical exemption will have to be obtained prior to arriving on campus.), etc. Anything for which I need to be prepared should be communicated to me before you arrive.

Address for Visa Documents

When you get here, the building you will be staying in is:

1455 E. 15th Avenue
Eugene OR  97403
                  

However, do not send mail to that address. Mail addressed to university buildings (as opposed to departments) is returned as undeliverable. Do not have things dropped off at the dorm by other couriers because there is nobody there when we are gone, and we will not be there most of the day. There is no phone number at the dorm, so you will have to use your own phone. You can give the department's phone number

The contact information for visa applications is

Zena Ariola
University of Oregon
Department of Computer and Information Science
1477 E. 13th Avenue
Eugene OR  97403
541-346-4448
ariola@cs.uoregon.edu
                  

Address for Mail Delivered by the USPS

US Mail must be delivered to a specific person at a specific department. So, if you must have mail sent to you while you are here, you will have to address it to me:

[you] 
c/o Jim Allen — OPLSS
Dept of Computer and Info Science
1202 University of Oregon
Eugene, OR 97403-1202
                  

Address for packages not delivered by USPS

If you are sending things, such as lost luggage, through a courier service, then you should give them the street addresss for Deschutes Hall

Unfortunately, all of my advice on coming to the United States is based on information from the Obama administation and before the COVID pandemic. I cannot offer advice on how to get to the US currently, but the following are the guidelines I have offered successfully in the past.

It is never too early to work on obtaining travel papers to the US.

For non-citizens of the US, you will need the following:
  • Travel papers to leave your country

    Most governments do not care if you leave their country, but the government of your country of residence may require paperwork to release you. To enter the US, your country of citizenship must issue you a passport, which may also be necessary to leave your country. When you leave, make sure you have any papers necessary to return to your country of residence.

  • Travel papers to enter the United States

    Most governments do care if you enter their country, and the US Government is no exception. To enter the US, you need:

    • A Passport from your country of citizenship
    • Electronic pre-approval to enter the US and/or
      a business visa.

      Many countries are in the US Visa Waiver Program. Citizens of those countries do not need a visa to enter the US for business purposes. If you need a visa, please read and follow these instructions carefully.

      OPLSS is a Conference, not a Course of Study

      You are coming here on business to attend a scientific conference. OPLSS does not grant academic credit. Although OPLSS takes place on a university campus, it is not a course of study. You need to be clear that you are looking for a B1 business visa. Do not under any circumstances say or agree that you need a student visa. Once you say that you want a student visa or that you want to "study in the US", you will never be allowed to come to the US unless you have been accepted into a US degree-granting program.

      It is illegal for us to issue you an I-20 or any other SEVIS document, because you will receive no academic credit from the University of Oregon. These are only required for a student visa. If you are asked for these documents, be very clear that you want a B-1 visa. You will not be able to attend OPLSS on a student visa. If some other institution gave you a SEVIS document, and you will be using it to enter the US to attend OPLSS before or after beginning your studies with them, please ask them about your visa limitations. If necessary, direct them to this page for clarification.

      Be Prepared for your Visa Interview

      Depending on your point of origin, the main thing the embassy will want to know in your interview is that you are not a "risk to emmigrate" to the US. The State Department says you will need to show

      1. The purpose of your trip — The US suggests that you not bring a Letter of Invitation with you; however, since I cannot convince anyone that it is useless, I will send you one; although it will be useless.
      2. Your intent to depart the United States after your trip — It is definitely required that you bring to your interview correspondence from your family members (not residing in the US) indicating that they expect you to return, and documents from your institution indicating that they expect you to return. Failure to prepare for this point may mean failure to obtain a visa. It is not a good idea to have anything sent directly to the embassy, since it is usually discarded unless you bring it with you to your interview.

        What is not helpful is any demonstration of a link, familial or otherwise, to a person residing in the US. Evidence of ties to US residents are generally taken as counter to this requirement. (i.e. If you are attached to people in the US, you might want to remain in the US.)

      3. Your ability to pay all costs of the trip — You must show how you are going to pay for travel and housing. You should have paperwork from whatever institution is paying. If you are paying for yourself, you should have financial statements showing you have funds.

      The decision to grant a visa is left up to the US ambassador to your country and there is no appeal, so be prepared. Talk to others from your country who have attended conferences in the US. Different Ambassadors require different levels of evidence. The University of Oregon has no influence with the US State Department.

      If you are on the Visa Waiver Program, and apply for an ESTA, you should read the information above under business visa, because you will be questioned at the border about the purpose of your trip.
Here, I will be posting updates on registration deadlines, when you should expect to be notified, how to get here, and what to bring, etc.

If you apply (with a recommendation) before April 10, you should hear back from us by April 20. If not, please send me an email asking what happened to your application.
