Hi, I am currently living in the United States as a high school Freshman. I know it may seem a bit early to be deciding my future, but I am considering joining the British army as opposed to the American Army(don't ask ;p). I know for a fact that citizens from Commonwealth Nations can join the British Regular Army. I don't think the USA is one, but Canada is, right? I was born in Canada and lived there till I was 6 and I have Canadian Citizenship, so that means I am eligible to join? What are my chances of getting in? I am reasonably fit and hope to continue this throughout High school. So are my chances of getting in good? And I am curious on the benefits of joining. If I serve more than 5 years I can get British Citizenship? Is this true? I think that'd be nice to have, but would i need to give up my American or Canadian citizenship? Oh, and also. I heard they are thinking of maybe capping the amount of people form commonwealth nations from joining and it is in debate. What are the chances of this happening? Thanks all EDIT: I am a little concerned on the eyesight part of joining. I heard the minimum requirement is 7 diopters. I don't know what diopters are, my contact prescription is negative 3.00. I don't know how you convert that to whatever your British use(or is it the same), I don't know.
