Immigrations documents for closed loop cruise travel

[kggokul]

Hi,

I am Indian and on H1 visa working here in US. I have valid visa stamped on my passport. I am planning for a cruise trip to Cozumel Island (Mexico) and return back to US. while returning back do I need to carry I-797 for POE at the port? or a Passport with valid stamped visa is good enough.

Thanks in advance.
