I have been accepted to an summer exchange program in the US and I began my J-1 Visa application. However, I received a much better offer by a major institution in another country (I thought my application failed, but it seems they were just delayed in the selection process).
I would prefer to take the second option, but I don't want to mess my inmigrant records because maybe, in the future, I would try to enter the US as a master or PhD student. So, is there a penalty if I withdraw the J-1 Visa?
