Hello!
My son, is working now in the US on visa J-1.
This visa expired at the end of August, and he has grace of another 30 days.
However,he was also issued B-2 visa (for 10 years).
My question is:
What does he need to do in order to change from visa j1 to b2 ?
Does he need to get out of US and return?
Can he do this at the Niagara Falls border station?
