My case (I140/485 concurrently filed) was transfered from CSC to TSC on March 23 and I got the receipt say TSC received my transfered package on March 29. Then it LUD twice on 5/22 and 6/24 respectively. A couple of friends around me they submitted their application at the end of last Sept. and they also got the LUD on 5/22, and 6/24, then they have already got their I-140 approved on 7/31/06.
My question is why the official in TSC touched my case on 5/22 and 6/24, and let it alone after that? anything wrong? May I write a letter to TSC and inquire the situation of my case? any advantage or disadvantage if do so?
Thanks a lot, have a nice weekend.
