I have a friend who is currently on a one-year student visa in Australia training Wing Chun. There's a bunch of classroom learning, and he has to attend like 75% of them or he gets it revoked, but overall I get the impression that it's kind of a joke. BJJ being as informal as it is, I wonder if it is accredited in any countries such that you can get a student visa for training BJJ there full-time. It doesn't even necessarily have to be Brazil. I mean, say you're an American who just wanted to spend a year in say, Sweden, hooking up with blonde porn stars? Can you just find a BJJ school in Stockholm and have them write a letter saying you're going to train there full-time? I mean maybe to make it all legitimate you have to watch some ADCC videos in class and write a term paper on half-guard sweeps or something. I dunno. I'm sure it varies by country, but has anyone ever looked into doing anything like this?
