Then he's the first person in history who goes from US to Poland to make money.
If he even gets a job, he ain't gonna make much. This is Poland, not Pittsburg. He must be out of his mind to think such a thing. What kind of work does he think he can find for such a short time? Not going to happen.
He's how old? Still in high school? Man, he's got a lot to learn about life, let alone life in Poland.
I don't mean to rain on your parade, but these are some seriously unreasonable expectations. Good luck.
