Technically once you file your papers for adjustment of status through marriage, you are no longer in F1.

no you need the actual gc to obtain the instate fee...however you can take a break once you receive the i797 receipt I think!

What will you tell them your alien number is and is restriction on your SS number removed?

How did you file Green Card. Did you marry a Permanent Resident or a US citizen?

I have done some research on this but the answer is very ambiguous. I have not found any clear answer. Attorney 1 says: as long as you maintain f1 status and pay international fee then you can get back to f1 if the case denies with whatsoever reason. Attorney 2 says: Once you file AOS then you cannot come back to f1 as you have declared that you have an immigrant intent which violates f1 visa. I want to find out which is better before i go to ISS. coz my advisor is last person you wanna talk to . she is a b*****. So i don't want to regret showing her my receipt and she takes me off frm sevis which will kind of jeopardize my situation.

No you can't go back to f1..and about the resident tuition fee, you have to be in the state for at least a year as a green card holder.
