Or study in Scotland where tuition should be free for you too. Only English, Welsh and Northern Irish pay in Scotland (Northern Irish seem to have the option to take up an Irish passport then qualify for the free tuition too - I'm sure someone else on HN will explain the mechanics of that). But it's not simply free tuition - you have living expenses too and moving to another country can make these much higher than a resident who gets to stay with their parents or relatives to cut costs.

I'm not sure how useful it is in general for people to forum shop round countries for education, except for Americans where going domestic seems to be a recipe for permanent debt rather than improving life opportunities. Even expensive countries seem to be a way better option for Americans seeking to avoid the constant thread of bankruptcy.
