Did you call the CIS? 回複：光有LUD看來是沒有用, 最近批的都沒有LUD.

When I dialed the CIS number, I found there is a choic that if your case was updated 6 days ago, but you have not got any information, please press ?#(I found the number). So I think you may try to see what happens to your case. My case was updated yesterday and today after responding the I-485 RFE(last month). I plan to call CIS next week if there is nothing happened to my case tomorrow.
