??/??/2013: NOA1 Issued
??/??/2013: NOA1 Received
6/26/2013: Transferred to TCS

8/6/2013-8/25/2013: Scheduled to be visiting/attending family stuff in UK and won't be available to follow up with the UCSIS. This schedule leaves something to be desired... but, hey, its progress!
... supposedly NOA1 was sent, but I have not received it; only subsequent mailings about a transfer after the fact.
