U.S. Immigration and Customs Enforcement is a federal law enforcement agency in a country.
Interpol is an international organisation and is essentially stateless, but must operate from some physical location
 Some countries determine the jurisdiction in these circumstances by means of policy and resource allocation between agencies, for example in Australia, the Australian Federal Police take on complex serious matters referred to it by an agency and the agency will undertake its own investigations of less serious or complex matters by consensus, while other countries have laws which decide the jurisdiction, for example in the United States of America some matters are required by law to be referred to other agencies if they are of a certain level of seriousness or complexity, for example cross state boundary kidnapping in the United States is escalated to the Federal Bureau of Investigation
