Did you complete the 4506-T online? If not, I'd call to check the status and see if they still need it from you.
It means they've received the paperwork. How long it takes will depend on if it's gonna be an auto or manual review.
Oh, sorry, I misread. I thought you had said you uploaded the form and then was trying to check the status again. All you can do is call them.
. My file is thin and I really wanted those cards , my Father have’em in his wallet .
Off topic, but just as a PSA: this generally isn't a great way to choose cards! Presumably your father has a different credit record and credit needs from you, what works for him may not be a good match for you. And, depending how credit savvy he is, he could have got those cards as a sort of default choice, and there may be better choices for him as well.
But good luck with resolving the app anyway!
