One of my colleague came to U.S. earlier this year on H1B, now his location and project has got changed and he is working on a different project for a different client who is located in a different State from last 2 months. His H1B (I-797) petitioner and employer (from which he is getting his salary is still the same).
Does he or his organization needs to file H1B amendment in this case or only LCA is sufficient?
Also, while this whole thing of filing H1B Amendment and LCA is in progress or not yet initiated, can he visit India for 2-3 weeks?
I have already gone through this question and link, but not able to understand whether amendment is required in this case or not?
