My friend & his family came back from India & showed H1B stamping in passport which was valid upto Sep 30, 2001. So they gave him I-94 upto Sep 30, 2001. He had new transferred H1B valid upto sometime in 2004 (long before he went to India), & I-94 that came with it. But he forgot to show it at POE. Now in his passport he has I-94 which is valid upto Sep 30, 2001 and he is having new I-94 which came with his H1B transfer (I think last year), which is valid upto 2004. But numbers are different on them. Could it be a problem?
