回複：回複：急:為何父母麵試後,綠卡在廣州移民使館等待6個月還下不來？

Thank you for your prompt response. My parents all retired last year; used to be professors and physicians at a medical school. What does CCP stand for? Any advice to expediate this security check? I'm thinking of writing a letter to Senator/Congress. Does it help? Thank you again.
