MY NIW case RD is 5/25/06. no LUD at all.
NSC is currently processing NIW cases as of Jun 01, 2006. You are still outside their processing times/dates whatever. Wait for another 2 months I guess then you will be IN and then if still nothing changes or ur case is not processed, then wait for another 30 days before calling USCIS. Thats the rule. ALl the best.
