Hi George, welcome to the forum!
The embassy's processing period for settlement visa is up to 3 months. But luckily some members here have received their visas in a matter of days, some in a couple of weeks and some took months. But don't worry coz you and the wife are not alone. I also lodged my settlement visa last Feb 15, so It will be my 4th week of waiting on Mar 15. I've noticed few members here and friends who had recently got their visas this week had received the same notice on Mar 6, apparently the embassy dispatch the processed visa application batch by batch. I think they doing some 'local verification check' that's why It's taking so long for others. We have no choice but to patiently wait.
I'm trying not to worry but I can't help it, the waiting causes me grave concern but I know good thing comes to those who wait. So hang on there, hopefully we all receive the good news very soon.
Juvy
