I suggest you stay in USA, but if you want come to Spain you need start again to get a JAA licence.
If you come here try in Gestair Fly Academy
| Formación Aeronáutica - Formación de Pilotos - España y Portugal, Topfly
www.topfly.com , Adventia
www.adventia.es,
FTE Jerez Flight Training School
No problem if you don't speak spanish
Are a few expensive but are very serious.
Good luck in your decision
