My sister-in-law parent got interview call for May 2019. He has some things to take care of this year and would like to interview in 2020. What is the process for rescheduling the interview? Should he get medicals done and then postpone?
My SIL's parent got interview appoint for May 2019. he is thinking of postponing to 2020. If it does not get it postponed and has to go for interview in May, how long will the visa be valid? Can he not use his Visa to enter US until May 2020?
Is visa valid for a year or less. Also, if visa expires, does he have to reappear for interview or go through whole GC application process again?
