Need Facebook Group List or Any working way to find them.

Hi guys,
I'm just a newbie. So I have planed to make some $$ from CPA+Facebook or Absense + Facebook.


But as I said, I'm a noob that's why I can't figure out the way to find Facebook active USA groups.


It will be great if anyone shares some active groups list or the way how to find them easily.


Thanks in advance
