"A travel document is an identity document issued by a government or international treaty organization to facilitate the movement of individuals or small groups of people across international boundaries, following international agreements. 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. However, the term is sometimes used only for those documents which do not bear proof of nationality, such as a refugee travel document." - (Wikipedia (en) 01.12.2020)
