Port of Entry

From VjWiki - The Immigration Wiki

A port of entry is a place where one may lawfully enter a country. It typically has a staff of persons who check passports and visas and inspect luggage to assure that contraband is not imported. International airports are usually ports of entry, as are road and rail crossings on a land border. Seaports can be used ports of entry only if a dedicated customs presence is posted there. The choice of whether to become a port of entry is up to the civil authority controlling the port; In the USA, for example, Los Angeles and San Diego are ports of entry whereas Newport Beach is not.
