Hi,
Firstly if you intend to do an integrated course, forget doing a PPL first. You get little or no credit in terms of training hours, and you might pick up habits that the integrated school wish to train you out of (even good ones)! By all means go and do a few hours to see if you really like flying, but stop there.
If however you choose the modular route, there is no reason not to do your PPL in the States if you are in a hurry. Again do your first few hours here, allow 4 weeks ,avoid the factory schools and allow for a few more hours here when you return. You could do it in the same over here if you are lucky, but, one word…WEATHER! Yes, if you could guarantee the weather you would be much better to do all your training here. You need to fly regularly to do your PPL quickly as continuity of flying makes a big difference.
Good luck
