Most white-collar criminals are released on bail. But after extradition, it's different.[1]
"The Bail Reform Act ... and the attendant presumption in favor of bail for persons facing trial, apply only to criminal defendants and are inapplicable to fugitives facing extradition proceedings. Because of the potential harm to the country's international relations that could result from flight, there is a presumption against bail in international extradition cases"
This is a downside of operating offshore to try to evade regulation.
