Hi,I am on J-2 visa an not working at present.my mother's visitor visa was
rejected 3 months back.I am going to reapply for her again.I dont know the reason for rejection last time.Last time we gave my husband as a
sponser.Should I change the sponser as my sister in India or my husband
can sponser his mother in law?My mother is a retired teacher.
