My friend filed petition for her sister's family 10 years ago. It got approved this year. Unfortunately the sister's son is over 21 now. He can not come with parents. Few months ago, he applied a student visa and was denied. The visa officer found out the record and he lied about that he had aunt in U.S. The son was scheduled another visa interview next month. What's the chance to get approved this time? How can they do to improve the chance?
His parents have not started the immigrantion process. After they have green cards, can the son get visit visa right away? Thanks!
