Work / Boyfriend going to Poland from the US to study may possibly live there [10]

My boyfriend is considering moving from the U.S. to Poland to attend school and make some money. He doesn't know if he's going to stay there for the rest of his life or come back to the U.S. after that. He also isn't even sure if he wants to go there for school. I'm really interested in learning about his culture (his family is Polish) with him and he's teaching me Polish and I'm very supportive of his thought process. He's taking off three months next year after high school to travel to Krakow to see if he likes it there and see if he really is interested in going to school there. Him and I are pretty committed to each other and we want to stay with each other for some time including his time in Poland (whether it is just those three months or if he goes to school there). I'm wondering if it is a realistic expectation that we will be able to get through that, I am pretty confident that would could. I'm just looking to get some opinion on it from people who have had international experiences (specifically regarding the U.S. and Poland) before.
