hi,
My H1B visa has stamped on Jan’15 for Client A up to 30th Sep’15. After that I never visited USA. Now I am going another Client B for which H1B Amendment along with extension has been done. As right now I am India, Shall I need to go for Visa stamping again or Can I travel to US with earlier stamped visa (which is valid up to 30th Sep’15) along with latest original I-797. Please help me.
