Not only would I apply to Club Carlson first (after freezing IDA / ARS), I would wait on the rest a few days until you get the approval message on the phone status (even if you see instant approval online, they review them all and it can be reversed). Then do Barclays, Chase, Citi in that order once US has cleared. There's minimal benefit to same-day apps anyway, so don't risk US considering it's highly unlikely you'll be declined on the others.
