I have a friend who is having L1 visa came USA two years before on L1 working in Company A. After coming USA he applied for H1 and got approved in 2008 October thru Company B. His status from L1 to H1 is also changed in Oct 2008. The candidate is still working in the company A (with L1 Visa).
1) How long he can work in Company B(with L1 visa)? (due to market down he is not getting job and may take time to get job on H1 Visa, to come out of the company A (L1)
What is the time limit to shift to H1 company from L1 company after change of status to H1 from L1.
2) Is there any impact in future (in H1 extensions or in Green Card process) if he continues to work in the same company A (with L1 Visa, even though his change of status is changed to H1 with new I-94 number)?
I think I have mentioned this in my blog earlier. Once the COS is approved and kicks in (October 1, 2008), he is NOT on L-1 hence the work on L-1 is illegal. This can have an impact on several things.
To correct matters, he must immediately reenter USA with an L-1 visa or apply for COS back to L-1.
