H4 - Latest I-94 expiring in Sep 2012 - I-797 valid until 2014. How to get new I-94

[golf21]

My son is on H4 visa. His I-797 is valid up to Dec-16-2014.

His passport is expiring in Sep-12-2012. He has I-94 valid up to Sep-12-2012(which is passport expiry date). This is latest I-94 that he received at port of entry.

how can I get his new I-94 with updated expiration date.

I will have his new passport ready in couple of weeks.

Can you please guide me the procedure for doing so?

You can either cross the Canadian or Mexican borders and have him return with a new I94 or you can have your Lawyer refile the H4 extension petition for your son and presumably the new approval will have the appropriate I94.
