My wife is in H4 and she is planning to go to school from Jan 2016. I was planning to change her status to F-1 after her school starts. If she applies TPS , she will have both TPS and H4. I was wondering if she can change her status to F-1 from H4 while holding TPS as well(either pending or approved).

Another thing is, can a person on H4 status use TPS EAD to work? what will happen to her H4 status if she use TPS EAD to work on H4? Let me know.
