It depends on the country and whether we have an information-sharing agreement. For example, if someone makes an application to enter Canada and applies for a temporary resident visa, and we have an information-sharing agreement with the U.S., they can advise us on information they have that would support the administration of their law. I'm speaking rather generally because I don't know the specifics of U.S. immigration law.
