I got an approval for change of status from INS for H1B to F1. My previous visa is H1B which is valid up to Dec\'2002. If I go to Mexico on this status, to attend for F1 visa. What is the probability that I will get F1 visa in Mexico and what are all supporting doc\'s required for it. What if F1 visa is rejected, can I come to US on H1B visa which is valid up to Dec\'2002.
Please provide info ASAP. I\'m planning to go India next month.
