Please do not worry about name check, no LUD, no LUD after I-140 approval or no LUD after RFE (on I-485). I have posted my I-485 approval recently. I had no LUD on my I-485 since Oct 19, 2006 (that includes my FP, I-140 approval). I had just one LUD on my I-485 and that was the approval email. In one word "patience", might be too harsh to say, but believe me, I-140 or I-485 approval is on its way.
