República Popular de Mongolia
During the Mongolian People's Republic, citizenship was determined by the nationality of the parents. A child with at least one parent with Mongolian citizenship automatically received the nationality of the Mongolian People's Republic, regardless of where they were born. Multiple citizenship was also accepted. The statute was agreed upon by the Mongolian Council of Ministers on 30 December 1974, and detailed further by an Instruction on the Fulfillment of the Statute on 11 April 1975.
