Received H1B Approval and want to travel on F-1 (OPT) before Oct 2012

[udayshri]

Hello,

I received my H-1 approval and my OPT is valid until Jan 2013. I want to visit India before Oct 2012 (i.e. before my H1B starts).

Can anyone please tell me if I need to submit anything to USCIS after I come back from India?

I had submitted my I-94 and I-20, and if I decide to visit India then I will have to get new I-20 and will get new I-94 while coming back. Do I need to submit these two to USCIS?

Thanks in advance.
