I am a US citizen and will be studying abroad in Mexico for the academic year 2017-2018. School starts in August but the school has yet to send an acceptance letter which is needed to acquire a student visa.
I will be going to my girlfriend's graduation in Mexico City in May, and would like to remain in the country from that point on (until school is out in a year).
I have been to Mexico several times before and each time was granted entry for 180 days. Assuming that I receive this same 180 day allowance, and I get the acceptance letter after my arrival in Mexico, can I apply for a student visa while I am already in the country as a tourist?
