I don't recall. I just checked a couple of times last week and it said 30 days and then just last night when I hadn't checked for a day or so it was approved. I did accidently call the wrong department at Chase 3 times because I thought it was the automated machine and hung up.
Maybe it explains the SL lol. Visa Sig with $500 limit.
If approved you'll also get an email saying welcome to amazon prime credit card to activate your card to your amazon account.
Sending approval vibes for you!!!
