Vincent, I read your question about going abroad to study architecture, and I would to give you some advices if you want to practice architecture in England. Better to finish your studies and have a degree in the country where you want to stablish your professional carrier. Also you can go the first year after finishing abroad to work at some office and also to a get the help of an scolarship with a program as Leonardo.
Every country has some rules to hability a forreign professional.
Since some years ago there are some agreements about this subject as the following. At the same adres also you can find the requeriments to practice architecture in other countries. In Belgium, for e.g. you need three years working at a office before your can work for your own. Even if you have been already building for 10 years in another european country. In the Usa, they recognise your european title, but to work as architect for a office you have to pass some tests, and if you want to practice and sign projects you must be registered and that means also more tests and evaluations.
