I found out on July 29th online on the app and than I got the Mail on August 5 (literally a week later) .
hopefully u get urs soon and more than likely it will be sometime in September as I never heard of anyone waiting over 2 months after receiving the letter.
imo, I would postpone the vacation since this is something worth doing asap, but if can’t make sure u call them to reschedule but that is also risky.
but I wish u nothing but the best on ur journey ❤️
