I am in a quite complicated situation, so please kindly advise me!
I am an incoming PhD student at a US university as an F-1 visa holder.
My mother has filed I-526 form during 2019, and my mother is expected to receive a permanent resident green card several months later. At that point, I will also be receiving a green card, because she has filed the I-526 form when I was under the age of 21.
My situation is that I will get legally married to a Korean citizen next year. If I were an F-1 visa holder, then my spouse can apply for F-2 visa and reside in the United States.
But since I will be holding a green card at the time that I will get married, I don't think my spouse can apply for an F-2 visa, and I think my spouse has to apply for a green card. The thing is I am aware that it usually takes 2~3 years for my spouse to obtain the green card, and my spouse cannot reside in U.S. until then.
In this situation, would there be any way for my spouse to legally reside in U.S. while waiting for a green card?
I appreciate any advice!
