Which I-94 to return at airport?

[blrmaani]

Dear all,

I have three I-94 forms:

1. One which I received when I came back from India in 2003. ( my previous employer)
2. One which I received after renewing visa in 2003 - part of I-797 ( my previous employer)
3. One which we received after H1 transfer to NEW employer - part of new I-797.

Which of these should I return at the Airport while visiting India this year?

thanks a lot
regards
