Hi, Team,

I have applied H1B through consultancy last year and it got approved.2 months back I got stamped as well.

This year I got H1B through current employer and it got approved as well.

I want to go to the US with current employer. what is the best option?

1.Shall I transfer the existing stamped visa to my current employer

2.Shall i go for stamping again with current employer H1B

Please advice on that.
