I've had mixed results with the 7-10 day letter--you know, the one you get when you apply for credit. Sometimes I have been approved, sometimes not.
I recently got the 7-10 response from AMEX when I requested CLI. I don't mind if they don't give me a CLI, but it would be nice to have more available credit so that's why I did it. Has anyone had a 7-10 day response letter regarding CLI and gotten approved with Amex?
