My wife's case and mine also had 2 LUDs recently. Not so sure what was that.
Last time I spoke to VSC they told me they are waiting on some additional security check results after my last FP 2 weeks ago.
After that, 2 LUDs happened. Btw, it happened exactly same day I made an Infopass appointment.
from what I read on the forum 2 LUD in a raw could mean anything:
1) Name Check results came in
2) Some sort of a reply to a status check being sent
3) Some sort of a Notice of Action being sent... could be a FP request, RFE, or... an Approval
4) could be an officer picked up the cases for a review...
I would wait about 2 weeks to see if anything comes through mail, if nothing call VSC to do another status check
In my case, if nothing happens till tuesday, I am going to see an officer in NYC using Infopass and ask him a couple of questions, it's been almost 5 years since I started this GC process, 5 long years... kinda frustrated already...
