I would have to say its a good sign. It sounds like Cap One is just looking to verify your info before they can approve the app. From what I seen, if they were to decline a credit card app, it wouldve already been done after you applied. If a CC company is looking to get more info from you, or ask you to verify some info...usually means a good sign. Good luck, hope you get the card. I just recently got mine and liking it.
