HI to L1 TO H1

[getkp]

Hi,

I was on valid stamped H1 working with my employer for 2 years.
Same employer filed for my H1 extension which I haven’t received on time,
hence employer filed my L1 as well on premium which I got within a month.
I went back to India got and my L1 stamped.

After I came back in US company also received my H1 approval which has longer validity thn L1.

Now I want to change my JOB can I use my approved H1 and start working for new employer by transferring the H1 to new employer.
If yes what is the procedure for the same ?
If NO do I have to get H1 stamped before I transfer to new employer?

Pls. respond ASAP, really imp.
Regards,

You can't "transfer" an H1B until it has been stamped and you commence working for the sponsoring employer.
