I got same promotion in email. Applied for it. Got message, we received application and will get back to you. It was not an instant approval. I have 770 credit score and only 1 active card from chase currently. It is chase preferred sapphire. Do I have to read anything in to this? Why was it not an instant approval? Usually when should I expect an answer? Shall I call them proactively?
Call in their Automated system. if they say "your application is now being reviewed, we'll notify you in writing in aprox.
2 weeks", then you have good chances to get approved, if they say: "7-10 business days", this means that you are denied, and you can call reconsideration right away.
This is a awesome method, i've tried it tons of times, and i found it to be very accurate.
