I held a H1b visa until May 31st. After this I had to apply for a COS to L2 as I had to leave the employer. The COS has since been in progress. I have now found a new employer who is ready to file my H1b visa. However, the attorneys want to wait until the L2 status is approved. I gather from USCIS that the L2 approval will take at least a month.
Is there a way my new employer can file a H1b visa on my behalf even as the COS is in progress? I am not sure if they are ready for wait for a month before initiating a H1b visa.
Also, I have an approved I-140 petition that was sponsored by my previous employer. The employer has also said that this petition will not be revoked. Will my new employer be able to file for 3-year H1b extensions based on the approved I-140 petition?
Thanks in advance for your responses.
