I have some queries,

I am on F2 dependent visa status. I want to apply for TPS and EAD too. I heard that F2 dependent cannot apply TPS and EAD together (it's because F2 is not allowed to work) but step by step i.e. once TPS status is approved, F2 can apply for EAD with TPS approved notice. Is this true or F2 dependent can also apply TPS and EAD together like others? F2 le after TPS approved status ma college jana paucha ki naai? or what if s/he wants to go college after some months when TPS is about to terminate? Is anyone here on the same boat? i need some suggestions please!
