Depends what you want to do...
There's aerobatics, tailwheels, differences training for VP prop and retractable undercarriage, seaplane class rating, an instrument rating or the multi-engine piston class rating you mention. That lot should keep you busy!
You could go to 'somewhere like the US' or somewhere like France, Spain, the Netherlands, South Africa, Australia or New Zealand. The world is your oyster.
Whatever, make sure to build a bit of experience between 'badges' - you'll learn more and the steps up will be easier. Most importantly, have fun with the training.
Good luck
