Law / Polish Citizenship for a foreigner whose parents was born in Poland [174]

Merged: Polish mother is now a US citizen. Polish Citizenship through ancestry?

I had a question... My mother was born in the 1950's in Poland and her parents and her family come from Poland as well. She moved to the USA with her parents when she was 13 and they have all since become US citizens. I was born in America but can I can I still claim Polish citizenship through my mother?
