H1 Transfer would get extra 1 yr beyond maxout

Hi,

I am nearing my maxout and my PERM labor is applied 6 months back but pending with DOL.

If my current employer requests for H1 extension I would get extra 1 yr beyond my maxout date as my maxout date will fall after PERM pending from 365 days.

If I want to transfer my H1 to company B would they as well get that extra 1 yr beyond my maxout or they will get approval only till my maxout date?

Thanks,

Hari
