Passport in the context of "Mail"

Passportization is defined as the mass conferral of citizenship to the population of a particular territory by distributing passports, generally within a relatively short period. This policy has been primarily used by Russian authorities who have provided easy access for persons born on the territory, sometimes holders of former Soviet passports, to apply for citizenship. In particular, the requirement of five years' residence on both Russian and Ukrainian territories is suspended for former citizens of the Soviet Union.

In general, a port of entry (POE) is a place where one may lawfully enter a country. It typically has border security staff and facilities to check passports and visas and to 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 as 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.

A travel visa (from Latin charta visa 'paper that has been seen'; also known as visa stamp) is a conditional authorization granted by a polity to a foreigner that allows them to enter, remain within, or leave its territory. Visas typically include limits on the duration of the foreigner's stay, areas within the country they may enter, the dates they may enter, the number of permitted visits, or if the individual can work in the country in question. Visas are associated with the request for permission to enter a territory and thus are, in most countries, distinct from actual formal permission for an alien to enter and remain in the country. In each instance, a visa is subject to border control at the time of actual entry and can be revoked at any time. Visa evidence most commonly takes the form of a sticker endorsed in the applicant's passport or other travel document but may also exist electronically. Some countries no longer issue physical visa evidence, instead recording details only in border security databases.

Some countries require that their citizens, and sometimes foreign travelers, obtain an exit visa in order to be allowed to leave the country.

A travel document is an identity document issued by a government or international entity pursuant to international agreements to enable individuals to clear border control measures. Travel documents usually assure other governments that the bearer may return to the issuing country, and are often issued in booklet form to allow other governments to place visas as well as entry and exit stamps into them.

The most common travel document is a passport, which usually gives the bearer more privileges like visa-free access to certain countries. While passports issued by governments are the most common variety of travel document, many states and international organisations issue other varieties of travel documents that allow the holder to travel internationally to countries that recognise the documents. For example, stateless persons are not normally issued a national passport, but may be able to obtain a refugee travel document or the earlier "Nansen passport" which enables them to travel to countries which recognise the document, and sometimes to return to the issuing country.

Photo identification or photo ID is an identity document that includes a photograph of the holder, usually only their face. The most commonly accepted forms of photo ID are those issued by government authorities, such as driver's licenses, identity cards and passports, but special-purpose photo IDs may be also produced, such as internal security or access control cards.

Photo identification may be used for face-to-face authentication of identity of a party who either is personally unknown to the person in authority or because that person does not have access to a file, a directory, a registry or an information service that contains or that can render a photograph of somebody on account of that person's name and other personal information.

Body identification is a subfield of forensic science that uses a variety of scientific and non-scientific methods to identify a body. Forensic purposes are served by rigorous scientific forensic identification techniques, but these are generally preceded by formal identification. This involves requesting a family member or friend of the victim to visually identify the body.

If a body is not badly decomposed or damaged, one or more persons who knew the deceased well can visually confirm their identity. Authorities will also compare supportive documents such as a driver's license, passport, or other authoritative photo ID before accepting a personal identification.
