Obtaining a Polish passport being a US citizen

I am interested in obtaining a Polish passport. I was told if I am 100% I can do that. Does anyone have information about this? A problem is starting to form because when my grandparents arrived at Ellis, it said they were German becasue Germany had owned Poland at the time. I am 100% on both sides. Does anyone know anythign about getting a passport being from the US. A friend told me all I have to be 50%. Thank you.

Contact the Polish consulate I guess for info.

However since you have the US passport, why would you want the Polish one,
it's less important than the US one.

No, it's not. With Polish passport you also gain EU citizenship, allowing you to travel throughout the Europe and work in most countries..
