I had gotten a 10 year multiple entry B1/B2 visa that I have used for tourism to the US. Now my employer is wanting me to attend a 1 month long training in the US after which I will be going back. I was wondering if I need a new Visa stamp or I can enter the US on my existing visa/stamp since it is valid and mentions B1/B2.
My 2nd question is, if I wanted to enter US 15 days earlier and visit my relatives there, and then join the training, is that possible. The letter I have from my company for the training has the real training dates. However, I wanted to come 15 days before that and visit my brother there in SFO and then head to NYC for the training.
Will appreciate a quick response from the experts.
