Here, I will be posting updates on registration deadlines,
when you should expect to be notified,
how to get here,
what to bring, etc.
April 1, 2023
Acceptance has been established for people who applied before the March 16 deadline.
By the end of the day, you should receive an email from me informing you or your status.
In most cases, some documents will be attached.
If you do not get any additional documents, it is explained in the email.
If you have any questions, or do not get an email from me by tomorrow morning,
(Hey, you in Austalia, Singapore, and Hong Kong,
tomorrow morning means April 2 AM to me, not you.
I don't have any idea how your timezones work,
or anything else.)
email me and I will see what happened.
You should get a letter of invitation and an invoice from me.
Your registration charge is determined by me and listed on your invoice.
When you go to the payment site, you need to pay the amount of money
shown on your invoice.
Do not pay for things that add up to more than your invoice shows you owe.
If you want to mske changes to your invoice, let me know.
In the email, I will tell you how I intend to write your name on "official documents."
In particular, if you are using the document to enter the US, please make sure
that the name I list matches the name on your passport, as the border guards
may want to see both, and the letter I send you will only be accepted
if it matches your passport.
Foreign Participants:
The letter of invitation has specific language for the
US State Department
during your visa interview, and specific language for the
US Customs and Border Protection
officers.
Whether you go for a visa interview or obtain clearance
through the Electronic System for Travel Authorization,
you should have the letter of invitation ready at the border,
and pay attention to my February 3 remarks about what not to say
during a visa interview and at the border.
March 20, 2026
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
is approximately the same
as the cost of a taxi from the Eugene airport to campus.
(If you are sharing a taxi, of course it will be cheaper for you,)
Book the train when you book your flight.
In the past, people have been stuck overnight in Portland,
because the train was full.
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.
To reiterate from the travel page,
if your destination is EUO or your train number is 4 digits,
you have booked a bus. If your destination is EUG
and your train number is 2 or 3 digits, you have booked a train.
A train is more fun if you are travelling with a group of OPLSSers.
If you tell me what time your flight lands,
I will tell you who else is arriving at that time.
On American trains, you are asked to use earbuds for phone
conversations and to listen to music/podcasts, but you are allowed
to have loud conversations —
this is America.
America does not have Harry Potter-style trains with each compartment
having three seats facing three other seats, but each car should have
two tables across for one another with four seats around each table.
If there are more than two of you, use those.

While you are in the US, you may need either a US State issued driver's license,
or a passport as personal identification.
In particular, if you go to any establishment that dispenses alcohol,
they will want to see your identification showning you are at least 21 years old.
In most states, including Oregon, each tavern, bar and restaraunt owner is required
to inspect the identification of every customer
(at restaraunts, only if they are buying alcohol),
and credibly believe that the identification is valid and issued to that person.
Unfortunately for Foreign participants,
this may mean that whatever identification you are using
is unfamiliar to the bartender and therefore, rejected.
Your passport should always be accepted.
A tavern, bar or restaraunt can lose its ability to serve alcohol if they do not comply
with this requirement.
Undercover police often enter taverns to see if they
get carded,
and if not, they shut the tavern down.
For example, I am over 60 years old, and I must show identification to gain access
to a tavern.
If I were friendly with the bartender, it wouldn't make a difference,
unless I'm OK with my friends being unemployed.
An attendee of OPLSS once said, "It's my right as an Englishman to get drunk,"
and I pointed out that English Rights don't extend to America
(c.f. Letter sent to King George III in 1776).
Febuary 17, 2026
To be clear: Housing on campus is arranged through me.
When I tell you that you have been accepted to OPLSS,
I will tell you I have reserved housing in the dorm for you,
and ask you to tell me if you do not want it before May 18, 2026.
Some people will pay through the credit card website,
some people will pay through wire transfers,
and some people will obtain a fellowship that pays for housing,
so the credit card website is in no way linked
to obtaining housing.
Going to the credit card website and paying for housing
does not guarantee housing is available.
You have housing reserved for you
when I tell you I have reserved housing for you,
and send you an invoice with housing listed.
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,
and if you cancel housing, I will send you an invoice
that shows you do not have to pay for housing.
If I tell you I have reserved housing for you,
please let me know by May 18, 2026 if you do not want housing.
On May 18, I must tell the housing authority how many rooms
OPLSS will be occupying, and the housing authority will charge OPLSS
for the number of rooms I say, regardless of whether they are occupied.
In particular, if you accept a fellowship from one of our sponsors,
you must cancel the fellowship by May 18, if you do not want to use it.
Sponsors will not pay for empty rooms;
although, housing will charge us for empty rooms.
Thus paradoxically, you must pay for an empty room not cancelled by May 18,
even if the room is free to you if you occupy it.
February 15, 2026
The housing authority has not yet identified the residence hall
we will be occupying, but the room layout for the dorm will be either
"double" or "single"
here.
If you have a double room, there will be two beds, but you will be the only occupant.
There is one communal bathroom for women and one for men.
The showers have a small, private disrobing area next to the private shower,
and the toilets are in individual metal privacy stalls.
If you need to stay an extra day, or arrive a day early,
it would behoove you to tell me as soon as possible.
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 a couple of blocks of the lecture hall.
There are, of course, more housing options in Eugene including AirBnB,
but the above hotels are within easy walking distance of OPLSS.
February 3, 2026 — For Foreign Participants:
It is never too early to work on obtaining travel papers
to the US.
The US President
has proposed an additional $250 refundable bond for visitors,
but if you complete the requirements before it is in place,
you can avoid the extra expense.
The following are the guidelines I have offered successfully in the past.
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",
or an official misinterprets your intentions,
including US border guards,
you will be turned away
from the US
until you have been accepted into a degree-granting program.
Neither electronic pre-approval nor a visa guarantee
that you are actually allowed in the US.
On the day you arrive,
a US border guard
will decide whether you are allowed in the US.
For that interview, the invitation letter I send will be useful.
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 you should check whether your government requires
you to file any papers.
Travel papers to enter the United States
The US has a
Visa Waiver Program
with many countries.
The Visa Waiver Program does not apply to all citizens
of Visa Waiver Program countries.
Travel to the United States under the Visa Waiver Program
A Passport from your country of citizenship
To enter the US,
your country of citizenship must issue you a passport.
Also, you may need your passport as identification while here.
When you fill out the electronic pre-approval form,
and when questioned at the border,
be clear that you are coming here
for a scientific conference.
Even though you will have to say University of Oregon
and OPLSS, you want to emphasize
that it is a
business purpose.
Do not write school, study or student.
Education purposes require a visa,
even from visa waiver countries,
and OPLSS cannot supply you with the required paperwork
to obtain a student visa.
Travel to the United States without the Visa Waiver Program
A Passport from your country of citizenship
To enter the US,
your country of citizenship must issue you a passport
Also, you may need your passport as identification while here.
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 ambassador
to your country.
If your interview goes badly, and you are asked
to do another interview, plan to bring more evidence.
If you have no more evidence, then there is no point
in another interview.
Be prepared for your visa interview.
Do not have anything sent directly to the embassy.
Bring all materials with you to the interview.
If some piece of evidence is not in English or not in the interviewer's language
(the locally spoken language of that embassy), it must be translated
by a certified translator.
This means, if you are studying in a country which speaks a language
other than your native language,
documents from your country of citizenship must be translated.
Here are the things you may need at your interview
at the US embassy:
A valid passport issued by your country of citizenship
A photo
(a copy of the photo you uploaded as part of the DS-160 application
Be prepared to submit all details of social media that you use.
Bank statements or other evidence
that you will be able to pay all the costs of the trip.
Letters or printed social media showing you will not overstay your visa.
This is very important.
The interviewer must be assured
that you are not a "risk to emigrate to the US".
Evidence of this type can be communications with
local relatives and friends showing they are dependent
on your return and\or communications from your employer
or academic advisor showing it would be more advantageous
for you to remain in your country/program than relocate
to the US.
All things being equal, the interviewer will believe
that it is advantageous for you to remain
in the US,
So, you must bring evidence to the contrary.
It is not useful to bring evidence of relatives or friends
currently living in the US,
as this indicates you may be a risk to emigrate
to the US.
I will issue a letter of invitation which you may also take
to your visa interview, but it is not requried.
The letter of invitation is used when arrive in the US.
I will issue an invoice which may be useful to you
in showing what your expenses will be along with evidence
of how you will cover your expenses, including letters
from your institution or other source of funds you will use.
Since I encourage you to begin travel preparations early,
your visa interview may occur before you receive an invoice
from me; in that case, you should bring a copy of the
rates page.
Travel papers to return to your country
Before you leave your country, make sure you have any papers necessary
to return to your country, probably, a passport.
