I just got the extension letter for 48 month of ROC. I don’t know is it because I wrote to my senators or I called USCIS. Maybe something helped. In the notice, USCIS said that they are working on cases that were filed before my case, which indicated that they should work on the cases based on the time they received.
I am surprised to see many people here discouraging me honestly. Maybe you guys are lucky and got your citizenship very early, so nothing to complain.
But it doesn’t matter, I will do what I can do for fight for myself. Even it didn’t work, at least I tried. I encourage other unlucky ones like me to do something too. Maybe the system will be fixed one day, who knows.
