回複：Need suggestion from 8 laoshi!

My EB1A based i485 has been pending 9 months, i tried SR, infopass and congressman, nothing worked. USCIS replied that security check is open, USCIS can not finish this in nine months.

Do you think i need to sue USCIS for this delay or just wait?

-Up to you. If you wan to, had better find a lawyer to help you.

The suing will result in longer processing or make USCIS speed up?

-If you win, your I-485 will be approved faster.

 Please give some advice. Thanks.
