I got the dreaded AMEX Fr email on 3/9 at around 4pm. They said they tried to call, but I didn’t get a phone call. I had racked up about $40K of charges on my biz plat cards over the last 30 days or so. I usually have little to no spend on my AMEX cards besides hitting the SUBs, so this was out of the ordinary. My mistake was not paying them off ASAP (I just forgot/got lazy.) Anyway, as soon as I got the FR email, I added a new bank account (DON’T DO THIS BTW) and paid them all down to $0.
They were asking for the last 2 bank statements on my cards. Luckily, I only had 1 bank account attached to my cards. Anyhow, on the night of 3/9, I uploaded both my existing bank as well as the new bank (the one I used to pay off the cards.)
I didn’t hear anything back on the 10th, 11th or 12th. Around 11AM PT on 3/13, I got a call from the FR team saying all my cards were active again. So it takes about 2-3 full business days to hear back from the FR. I consider mine a ‘light’ FR because I didn’t have to submit any past taxes or W2 statements. It’s odd because I hadn’t made any bank changes until after the FR and my last cc’s were back in December, so I’m not sure why they chose bank statements vs tax returns. Lesson learned – if you’re going to ramp up spend on AMEX, try to pay it off asap so you don’t get FR’ed.

I’m surprised you don’t just push out the payments with bill pay. They can’t demand bank statements if you never link a bank 👉🏻😉
