Am writing on behalf of my son who’s immigrate visa has expired two years ago . He went for the interview got the visa but because of his academic work and he was also selected to join a national under 15 basketball team so he couldn’t relocate to the United state . But after two years he has decided to come to the United state but his visa has been expired. My question is where should he start from ? Should we start everything afresh or contact the nearest embassy if he can reapply .
