回複:再問皮匠:可不可以用隨I797來的I-94,因為它還有有效期。

No, the last I-94 is the valid one.

Two solutions:
(1)To correct it on CBD;
(2)To go outside/reentry US, you will get a new I-94;

I know someone in the same situation as yours. But the worse part for him was that he was H1 and I-94 expired for a couple months. The firm lawyer suggested to take the second way. They do not want to tell the VO that he has been out of status for a while. He had a one day trip to Vancouver and got a new I-94.

I also remember that someone in this site said that they have corrected the I-94 at SFO airport.

good luck
