1. Can company C start h1b transfer and if yes, will I have to provide h1b transfer receipt from B to Company C?
2. I am going to join company C. So if I don't join company B, can I just use my current company's I-797 for h1b transfer with C?
3. Will I have to share info of company B with C or vice versa? Or should I tell company C that company B has already started h1b transfer?
4. Should I ask Company B to cancel the petition if that helps in any way?
