OK, I will wait for the letter . Still don't have anything from them yet ip yo date.Your application is unusual and it's difficult for any of us to guess what is happening. I would recommend you not worry until you have the letter. It may very well be a positive decision. The fact that eligibility and background check both show in progress (rather than completed) is strange to me.
But anything is possible.
Good luck.
Really praying and hoping it's good news.
