I'm in ! I'm so happy and excited for everyone. My letter was post marked 3/14/18 and dated 3/13/18. If you haven't gotten your letter yet it's coming :)
I also read in the 2017 posts that most letters came March 16, 2017 and for the year before around March 11, 2016. So it looks like we will be waiting for a minute.
When I met with a counselor I was told that it take about 5 weeks from Jan 1, 2018 to go through all of the apps. The letters are all mailed at the same time and they have until March 15, 18. I am also waiting : )
