I agree with the others. If you get the chance to obtain a standalone FAA PPL in addition to an EASA one, grab the opportunity with both hands. I think I once calculated that the cost will only be an additional 400 dollars or so, but the benefits may well be worth it in the future.
I wish I would have done the same thing when I was in the US for my JAR-FCL PPL. In hindsight, no doubt about it.
