An international zone is any area not fully subject to the border control policies of the state in which it is located. There are several types of international zones ranging from special economic zones and sterile zones at ports of entry exempt from customs rules to concessions over which administration is ceded to one or more foreign states. International zones may also maintain distinct visa policies from the rest of the surrounding state.
