What do you put in class of admission
F1 or H1

What question, and what form.
I think they are asking about what was your status the last time when you entered USA?

I131 form advance parole question 3

Whatever status you are in at present..

I came as F1 but now in H1 so what does it mean by class of admission is it when I came first or status I am in right now

It'll be h1.

@ microbiology,

class of admission means, when you enter port of entry, what does your I-94 says. Suppose you came to us as a student as F1 and never left US then your class of admission is F-1.

If you completed your studies, got H1, went to Nepal or left US and come back again after visa stamping then your class of admission is H1.

Never left after I came so it's F1
