我的H1b到10/21/2013。在extension過程中我回國一次,等我入境時按照我原來的H1b給的I-94
-Do you mean you went to China during the H1 extension pending? If so, was your H1 extension approved before you reentered US or after you reentered US? You should get a new H1 I-94 with your h1 extension approval, shouldn't you? What is your new H1 extension approval effective date (i.e. the new H1 I-94 effective date)?
