So here's the situation.
My mother just got her green card, and she wants to petition for her unmarried son over the age of 21.
My brother can also get a B-1 tourist visa from the Philippines. Should we file the petition while he's outside of the US or when he arrives in the US (Or does it make no difference at all)?
My mother wants my brother to come and go to US every couple months (try to renew his I-94 and what not) while my brother waits for the application to process and get an immigration visa number.
