我的背景调查接近两年了，有没有什么可以做的呢？
-Based on the immigration law, if your name check pending has been over 180 days, USCIS need to make a decision on your I-485 if your PD is current. So, you may file a lawsuit to the Immigration court against USCIS if you want to. Of course, you may ask the US Senator/Congressman in yoiur state to help you first and if it does not work, you may file the lawsuit.
