Legal Question in Immigration Law in New York

The problem with applying for a change of status is that usually the I-539 takes longer to adjudicate than the approved period in B-2 status will be, so the applicant usually ends up accruing illegal presence.

You have a 60 day grace period from the date your F-1 status theoretically terminated (i.e., date you graduated or dropped below full time student status), so that might be all you need to tie up loose ends & return home.
