My Current Employer A has started my H1b transfer under normal processing. I have resigned and joined my employer on getting H1b transfer receipt notice.

In case H1b transfer started by Employer A is rejected :-
1. Can I initiate fresh H1b transfer by joining other employer?
2. What will be my status in case H1b transfer rejects?
3. How long can I stay with in country? Is there any interim grace period where I can search job and go for fresh transfer.

Please advice, as I am bit tensed.
