Its good you realize now about not getting to stuck on the long-term. It's something I was bad with in my early twenties.

As for your next steps, it kind of sounds like you know already. I will throw in some suggestions though.

Get yourself a quality used econo car that can be bought on the cheap. Secret is runs great, but doesn't look great. i.e, 2002-2005 Honda Civic. Drive it into the ground locally and then longer distance.

Then, but everything but what you need to live and work into storage (or store at home if an option) and then move/drive to a U.S. city you would like to check out.

Stay there for atleast a couple months to get the feel of it. Be sure to do activities that force you to network with people. I

f you like it, stay or use it as a launching pad for overseas. If not, you can always go back to familiar territory.
