Hi Peter, is there a way to transfer F1 to J1 visa, so that me as a SO of the F1 holder can get J2 (as a spouse) to be able to work in the US? More specifically - that would be the only reason for my SO to switch the visa type, which IMHO is not sufficient.
It's possible but this would depend on both your school and the particular J-1 sponsor. Usually, it's not possible if it's to switch from F-1 OPT to a J-1.
