Can I travel & re-enter the US with H-1B approval notice but L-1B visa expired in passport

[kminer]

I came to the US in 2008 on an L-1B stamp in my passport. That visa has expired and in the meantime I have an H-1B approval notice (same employer), but don't have any new visa in my passport because I haven't left the US.

I plan to travel to Mexico. How can I be sure that I am allowed re-entry in the US?

If it's a short trip of less than 30 days to Mexico, you can use automatic revalidation to re-enter the U.S. on your existing I-94.

Otherwise, you will need to get a visa while outside the U.S.

That's interesting, thanks newacct.

How many times can use this automatic revalidation?

No limit, as long as your I-94 is valid.
