You are probably in the same situation as me and some other early unlucky ones. In my case, I'm in this giant 'queue' behind many 03,04 filers waiting for 2nd FP scheduling. It seems until the 2nd FP complete, there is nothing CSC can/will do.
Here is the response from CSC about 2 month ago when they finally respond to my inquiry:
"All I-485 cases that are previously considered beyond JIT processing are being re-assessed. The cases that are fingerprint ready will be reviewed. The I-485 cases with expired fingerprints will be re-scheduled. Please allow 60 days for action on these cases."
Later the response from CSC to the inquiry made by local congressman office says the case has already been reviewed, now is pending for re-fingerprint scheduling, no timeline can be given...
My lawyer tried the same old "security/name check" trick, but the response from congressman about still waiting for 2nFP have them shut up on that excuse.
Bottom line, I have no clue what else can be done. My LUD changes 11 times from end of June to July. It is now a "problem case", but still nothing happens. I don't see any hope but seeking therapy to keep sanity.
