Hello, this question is for my cousin who recently applied for tourist (B2) visa at Mumbai consulate in India. When he got his passport back he noticed that he only got single entry with 3 month visa validity (US visa expires in June). The thing is that he was not planning to travel until later this year as he has commitments in India in June (medical clearance exams, pending covid vaccine etc). What are his options at this point? If he doesn't come to US on this visa before June, is he eligible to apply again or renew it? How will that application go (what are his chances of approval or renewal at that point?)? I want to know if someone was in similar situation and can offer any inputs. Thank you for your help in advance.
