Instead, airlines are in charge of swiping travel documents and uploading the APIS data to CBP/ICE to determine an individual's permission to leave the country.
It's the same in Canada, yet most Canadian international airports have 'international' depature areas. Once you've entered it, to exit the international (or transborder) area you have to proceed through Canadian customs and immigration.
