Refugee Travel Documents (1951 Convention Relating to the Status of Refugees)

Refugees are not allowed to travel using passports from their countries of origin, as they are no longer under the protection of that country.
Refugee travel documents are issued to refugees by the country in which they are residents instead of a passport.
Refugee travel documents may be regulated by the 1951 Convention Relating to the Status of Refugees. The 145 states which are party to this convention are obliged to issue travel documents to refugees lawfully resident in their territory.
These documents allow a refugee to travel out of and back into the country, usually according to the rules which apply to nationals of that country, but depend on the country they are travelling from/to.
Refugee travel documents are passport-like booklets. The cover has the words 'Travel Document' in English and French, and usually the language of the issuing state. It also contains the date of the convention: 28 July 1951. These booklets can come in a number of different colours, and have two diagonal lines in the upper left corner of the front cover.
Countries who are not a party to the 1951 Convention may also issue travel documents to refugees, however these documents may not offer the same travel benefits as a 1951 Convention travel document, and may differ in appearance from the 1951 Convention travel documents.
