A lot of the recommendations above only apply to FAA PPL though.
There's only a handful (6, to my knowledge) of schools in the USA that are authorized to train you for the EASA license - to my knowledge, it's 6 in total: 5 in Florida and 1 (mentioned above, at Gillespie Field in California, AAA American Aviation Academy as it's now called).

There is an ABUNDANCE of information this topic in there... Read it carefully and multiple times...
I've also written an account of my time there, you'll find it here:

Good luck and keep in mind that before venturing to the US, some paperwork is required at home. I'd suggest to plan at least 3 months for this.
