try to get the contacts of IAESTE (international assoication helping the students of engineering, architecture etc finding trainee places or det. time works in other countreis)- they should know about it in your university.
i have worked 'abroad', maybe in 6 or 7 countries by now, and i assicure that britain has the best wages! but if you want to SEE what is like to live elsewhere, GO!
FIRST decide WHERE YOU WANT TO GO and then comes the rest!
i could have some tips or some contacts for architects and studios if you happen to want to go to brasil, milan, naples, ...
if you'll plan to live a year away, you can always start a part-time work (e.g. in a pub; fast to get in many cities, supposing you speak the language) (or if not you could sure teach english!!!!) while you are looking for a full day job in the studios!
if you think i could help lemme know
