My question is regarding conversion from H-4 to F-1. I landed in the US on an F-2 visa, which was later converted to an H-4. So I don't have a sticker visa on my passport. Now I'm trying to gain admission to a university and change my status to F-1 again. Would I face any issues in this matter now or later? If I don't manage to get a job later, would I still be able to stay and convert back to H-4, or could I possibly face a denial?
Secondly, if I go back home and get a visa stamp, can I face any potential problems because this is going to be my second master's and I've gone through three visa status changes in a short period?
No, there's no limit to how many times you can change your immigration status within the U.S. As long as the changes (e.g., F2 to H4 to F1) are legitimate and not just for "fun," they should not pose a problem for future denials or visa stamping.
