My wife is in F1 status right now. I want to change her status from F1 to H4. Actually, she came as F2 and changed her status last year to F1. I am going to file I-539 on Monday, the 16th. My question is: what will happen to her status once USCIS gets her application? Is she have to be in F1 till her change of status will be approved( I mean she has to join college in this fall) or she will be in change of status and she doesn't need to attend college. I really need to know whether she needs to go college or it's not necessary to join college. Thanks in advance.
