H1b transfer approved but dont want to join
My H1B transfer to Uber got approved but I do not want to join it anymore and stay with Microsoft.
1. Can I still stay with Microsoft?
2. What would happen to the H1B petition with Uber which got approved?
3. Can Uber sue me because I cost them money here?
Reason for not joining Uber anymore is Im scared of layoff in this visa situation.
