I don't see what that has to do with getting a job as a CFI when you don't even know if you can solo a plane.
Flying to the US, irrelviant
Spending 50k, irrelevant
"Starting a new life", irrelevant
As I said haven't even soloed yet and you're thinking about where you're going to get a flying job, come on now lol!
Heck, you might not even have the chops to solo, or get your IFR, or CFI and the washout rate is rather high in aviation.
I applaud your....enthusiasm.....and having a plan is a good thing, BUT trying to plan as far ahead as you're attempting is a waste of mental energy and time, come back when you have 250+hrs, your CPL and are about to start in on your CFI and I'll make some recommendations.
