From what I recall the FAA has withdrawn authority/approval for writing the FAA exams outside the USA since May/June 2004. Wanted to write mine in Europe but failed to find a centre so had to head for the USA. It's not very expensive though and is worth the while. There's one centre in Paris at Le Bourget where they used to offer the full FAA ATPL. You could try to find out from there if they are now offering the FAA exams or if the ban has been lifted for other centres in Europe
