Non-citizen travel document

A non-citizen travel document, also known as a passport for foreign nationals, alien's passport, non-citizen's passport or passport for foreigners is a travel document issued by a country to non-citizens (also called aliens) residing within their borders who are stateless persons or otherwise unable to obtain a passport from their state of nationality (generally refugees).

Some countries issue two different types of non-citizen travel documents, one to refugees (known as 1951 Convention travel document) and another to stateless persons (known as 1954 Convention travel document).

Visa requirements for alien's passports / certificates of identity are in general different from those for regular passports.

Some states also issue certificates of identity to their own citizens as a form of emergency passport, or otherwise in lieu of a passport.

Types

1951 Convention documents (for refugees)

A certificate of identity issued to a refugee is also referred to as a 1951 Convention travel document (also known as a refugee travel document), in reference to the 1951 Convention Relating to the Status of Refugees. 145 countries are parties to the 1951 Convention and 146 countries are parties to the 1967 Protocol Relating to the Status of Refugees. Notably, the United States is not a party to the Convention, but provides travel documents to its lawful permanent residents, either as a U.S. Re-entry Permit or a refugee travel document under the 1967 Protocol.

1954 Convention documents (for stateless persons)

A certificate of identity issued to a stateless person is also referred to as a 1954 Convention travel document, in reference to the 1954 Convention Relating to the Status of Stateless Persons. 89 countries are parties to the 1954 Convention.

Unlike a refugee travel document, a certificate of identity issued by most countries does not in itself entitle the holder to readmission into the country.
