I'm an American who got a job working for a private school by the name of SMART in Medellin. I start next month! I actually want to go to Colombia before I start though. So in that case, 8/ it possible to apply for a work visa within Colombia? Or do I have to leave the country, and then enter again? I would do the whole process here in New York, but the company is yet to send me the information for applying for the visa.
