I am on L1B VISA currently for company A and Company B filed my H1B VISA through consular processing though I am in US. My petition was approved in Sept'2016 but company B asked me to join now and they are now filing my L1 to H1 COS from H1B Consular processing.
I have following queries.
1. I have an offer from Company C and i want to join them after L1 to H1 COS is approved. Can I join company C within 15 days of joining Company B and without generating paystub on H1B for company B ?
2. Can Company C file for my H1B transfer by only using H1B petition ?
3. Is it required to go for stamping or COS will be fine for 2nd H1B transfer ?
