Hi - I am currently on H1B and my I797 validity is till Nov 11th 2017 I got my VISA stamped Feb 2015 and is valid till Nov 11th 2017. Recently my office location changed from location A to location B, but everything else remains the same. I was asked to file for an H1B amendment and LCA amendment based on the new rule. I am currently planning a vacation to the Caribbean and was wondering if my stamped VISA is good to travel outside the US and re-enter. Appreciate your thoughts.
