Experts on this board:
I am an H1B visa holder, and I plan to attend a meeting in Canada early next year. I have already obtained TRV visa to enter Canada. My questions are about re-entering the US.
1. Do I need a visa to get back to the US if this trip is less than 30 days?
I originally came to the US on F1 visa, and I do not have a visa stamp in my passport that corresponds to my H1B status right now. ALSO, I HAVE ALREADY SUBMITTED MY I-140 FORM (IMMIGRATION INTENT?)
2. What document do I need to bring for this trip?
Thank you very much! Any information will be appreciated.
