Depends on the company. Many do, since the H-1b to permanent residence through PERM route is easier than L1. However, you may qualify for EB1 managerial/ executive category for permanent residence, which is an easier process than PERM, so you may want to check with recruiters beforehand what their internal rules are surrounding that.
Why or how is L1 to permanent residence more difficult than H1b?
Did you figure this out? I have the same quesiton
Generally not. I know fb and Google offers have 1 year validity so it might work out. Check with ur recruiters.
Fb and G won't apply H1 for you in this case from L1 even if the offer is valid for a year.
Well OP, there u go. Unfortunately, u r stuck on L1, wait until ur H1 gets picked up thru MSFT.
