Hi everyone,
I am sorry to ask this question again .I do know there have been discussions earlier about this.
Could anyone please clarify the Class of admission field in the Advance Parole - I131 application ?
My wife came to the US on F1 .That was her status when she last entered the US as well.She now is on a H1-B since 1st October 2006. The H1-B is not stamped on her passport .
In this case, is the Class of admission , F1 or H1B ?
Aprreciate all your help.
Thanks

F-1, as that was the visa that she was last admitted on.
