i'm looking to work in Poland as graphic designer
There's no shortage of graphic designers in Poland, or anywhere else in the world, for that matter. Far more people graduate with degrees in this field than there are jobs available.
Don't waste your parents money. Study engineering instead. Especially petroleum or geological engineering. Your lifetime earning potential will be many times greater than for a graphic designer.
Have to agree that Saudi Arabia or another rich Moslem country would be the best place to do that. Or in one of the richer Western countries like Switzerland, Germany, Sweden, the UK or the US, if you can afford it. I can't see a degree from a photography school in Poland being worth much on the job market anywhere in the world. Even if you were to get into a serious art academy, it would also probably be not worth the investment.
Also, Polish is not an easy language to learn. In fact, it is one of the hardest. It will take three or four years of hard work to develop passable speaking skills.
