As someone with a high school diploma and nothing else, and zero cash in the bank? Those are the folks to whom enlisting is appealing (in the US, at least). Not college grads in hot, in-demand fields with at least five figures liquid and ready to spend on immigration expenses.
I'm in the same boat as you are more or less - just have cash in the bank - beyond that everything I do is based on North American standards - much of it does not directly translate to Europe - if I wanted to remain employable, Canada or Australia is where I would have to go, as in my industry they're closer to the US technically.
I had known many who made the US-EU jump, it didn't sounded particularly hard (the administrative part)
