我的I-94是F1时（07年10月入境)的，可以使用吗？

Dear Pjiang,

Thanks so much for your reply. but I am not sure whether my I-94 card is still considered as valid one, since my last entrance was in 07 when I was a student. Now, my status is H1B.

another thing is I possibly will submit the GC application before the meeting, do you think it will affect my entrance back to US?

Thank you very much for your kind help!
Have a good one
