Late reply - sorry. You can do an FAA CPL but you get precious little credit for it when you convert to EASA, you will be credited the hours you fly and get some concessions towards the training required for the EASA skills test. There are big questions hanging over the quality of training you get in the US, some flight schools are very good but the generalisation would be you buy cheap, you get cheap. If you have no or very few hours I would suggest a PPL in Europe, hours building anywhere, but use the time well, don't just burn holes in the sky, then ATPL theory in Europe (but there are ATOs who can deliver this in the US as well) followed by flight tests in Europe. A subjective view.
