Green Book (Tibetan document)

The Green Book is a document issued since 1971 by the Central Tibetan Administration (commonly known as the Tibetan Government in Exile) to Tibetans living outside Tibet, and described by the issuing organization as "the most official document issued by the Tibetan Government in Exile." More than 90 percent of Tibetan exiles own one. It serves as a receipt book for the person's "voluntary taxes" to the CTA, and has been described by a CTA official as "the passport of the exiled Tibetans to claim their rights from the Tibetan Government in Exile". The CTA says that in the future, the document "will become the basis for claiming Tibetan citizenship".

The document is valid for five years.
