Super interesting take you mentiom.

Tourists can drive in the US on their foreign license. Can that be used as a loophole for a call center?

Also, maybe it is a gray area where they are not asking what they don't want to hear. Those offshore subcontractors already break any US law they want because they aren't hiring humans inside the US, they are providing a service from abroad.

Specifically, how do you know the operator can drive?, as you ask. But also, how do you know your operator won't steal your PII / bank account details out of your law enforcement physical jurisdiction?
