回複：回複：回複：NSC I485 approved

Do you have several LUD just before case approved? I have no LUDs for my 485 for 4 months, even fingerprint did not trigger and LUD. However, 3 weeks ago I receive RFE for TB skin test and I ted RFE materials last week. Now my online message changed to RFE materials received and there is a LUD the day after that. How long do I have to wait? When I can expect to have freedom?
