Medical Wavier Granted (Color Deficiency) Letter?

Nov 30, 2016
I was granted a color deficiency waiver from USNA at the end of January. On my portal it states that Date Letter Sent - January 31, but I have not received anything yet? Should I have gotten something in the mail?
Not sure if this is still active but.... It depends on where you live. I am a 22 hour drive away and it generally takes 10-12 days for the letters to get here. I've received 2 waivers from 2 different Academies but I haven't been sent any letters as everything is electronic.
