Mexico business travel

[Sid.R]

Hello,

I have a 5 day business trip to Mexico sponsored by the company I work for coming up very soon. (As per the information from Mexico embassy, I have been informed that I would not need any other visitor visa since I have a valid US Visa)

As of now, I am in my initial OPT period which ends in Feb 2017 and I haven't applied for the Stem extension yet. 

I would like to know if there is anything I will have to make sure about before leaving for this trip as a precautionary measure.

Also, it would be great if you can give me a list of all the supporting documents I need to carry during this trip.

All your responses will be very much appreciated.

Thank you.
