Got RFE for OPT EXT & Planning to do second masters

[raj969]

Recently,I called USCIS about my OPT extension and they said they will be updating me the OPT status with in 15-30 days.Incase if my OPT is denied or if they send me second RFE then I am planning to register for the second masters in MBA for the summer and my visa is getting expired on Aug 2013.In this case when I registered for second masters I think my OPT extension will be terminated.If it is so can I renew my visa? If yes what are the chances of getting

visa renewal?Also can I go for visa stamping in countries like Canada or Mexico for my second masters and what questions I can expect from them?
