Editing Port of entry (section)

==Variations==
In some countries, immigration procedures are carried out by the armed forces rather than specific immigration officers. However, in most, the levying of duty on imports is still carried out by customs officers. Immigration clearance in some ports of entry have automated sections open to the country's own residents or citizens, such as the [[E-Channel (Automated Passenger Clearance System)|e-Channel]] found in [[Hong Kong]] and [[Macau]], [[Global Entry]] found at some airports in the United States and other similar country-instituted programs.

On some international borders, the concept of a port of entry does not exist or is at least not applied to select countries of free-crossing pacts. Travelers may cross the border wherever and whenever convenient. For example, and as such a pact, most EU citizens may travel freely within the [[Schengen Area]], which is made up of 29 European countries. As with the example, in some cases, such free travel may be restricted to citizens of specific countries and to travelers who are not carrying goods over the customs limits; others may only cross the border at a designated [[Border control|border crossing]] during its opening times.
