If someone with F-2 visa comes to the US with her F-1 spouse, then they apply for EB2 green card(in fact the F-1 visa holder as the primary applicant and F-2 visa holder as his dependent), then could get accepted and get their green cards, and after that they get divorce, what will happen for the wife who was the dependent applicant throughout all the procedure? Will her green card expires and she must leave the US?
