It may help that we bank at all of the same banks as Kraken, so most transfers are internal transfers. But even to outside banks, normally US wires should be pretty fast (usually within the day). It may also be the case that we literally wire millions every day on a regular basis, so our wires probably don't get held up at any compliance checks.
As a start, you can check out Signature Bank and Silvergate Bank. They are known for being crypto-friendly banks, and they bank literally every exchange that trades crypto versus USD.
