Thanks Happyface, I have all the documents you mentioned but the OPT Card. I went from F1-CPT-H1, (got a degree while in CPT). CPT is just an I-20 authorizing employment. I didn't get OPT coz I was late applying for it. So I had to enroll in another degree and took the CPT and applied for H1, and got it approved. I think its a bit risky to go to Mexico in this case, just in case they ask for OPT. -R
