I just found my I-94 was stamped valid only until March 30/04, it was stamped when I came back from Feb.29/04 (it seems that March 30/04 was based on the H1B visa on my passport), but my H1B document will valid until 7/31/2006. Is there a chance to corrent my I-94, what I need to do? Will I be in big trouble? any experience to share? thanks a lot.
