In short, the question is whether I can enter the US under the visa waiver program for a research visit at a university, given my particular situation (details below). Basically this question, but with extra complications.
I (citizen of a EU country, PhD student) am in the US for a 6-month long research internship as a visiting student. A couple of weeks ago, my passport, which contained my J1 visa, was stolen. I was able to apply for a new passport, but the only way to get a replacement of the visa is to re-apply for a new visa, which cannot be done in the US (only at a US consulate or embassy abroad).
Now, if I planned to stay in the US until the end of my visit anyways, there would be no problem. However, I had planned on leaving the US for a few days around one month before the end of my internship, in order to attend a conference. There would be no time to apply for a visa during the conference time, and in any case would be too risky.
So now my question is whether I am able to leave the US for this conference: since the remaining time I need to be in the US is only about a month, can I re-enter the US under the VWP, instead of applying for a new visa? Basically my strategy would be to "convert" the remaining one month to an informal "research visit" for which I can enter without a visa.
If needed, I can explain the situation to my host professor/university and get a letter of invitation for my 1-month "research visit". Note that I am getting paid for this internship, but not through the US university or any US entity: I'm getting paid from my home institution to my non-US bank account. In addition, it is formally not a "salary" for any "work" that I am doing in the US, but rather a stipend to cover my living expenses in this time period to allow me to perform research.
The main differences that may make my case more tricky than in the other question are, I believe:
- I am unsure if it counts as "working". Note that this applies equally to the other question, where the person is also a PhD student getting paid from their home university, but perhaps it is a different kind of grey area here.
- My stay in the US is only one month long, but it is part of a longer visit.
If the answer is essentially "yes", a further question would be: is it better to really try to present this as a "1 month research visit", or is it better to be upfront and explain the whole story (i.e. from my passport getting stolen)? In that case I can also ask for the "whole story" to be included in the letter of invitation. I can also show a copy/scan of my J1 visa (which I do have).
