Also, what I was originally asking is if I reached a certain rank in one place, would it be recognized somewhere else? Or would I have to repeat the examinations? I don't want to be held back for too long just because I moved to a different country.
Re: being "held back", is your concern that not having a certain rank will somehow restrict what training is available to you? If so, I wouldn't worry about that. You'll be able to train according to your abilities, whatever they are - it doesn't matter what rank you hold or what color belt you're wearing. If by "held back" you mean "not get a certain rank", well, yeah, that's a possibility. But I think you said that that that's not your concern.
