The national government issues passport to their citizens on request. The valuable document contains important information regarding the identity of the person like name, sex, date of birth, address, place of birth etc. The document is essential for international travels and the possession of the passport gives the passport holder the right to return to the country which has issued the passport. A visa on the other hand is issued by the embassy or consulate of a foreign country. It gives the visa holder the permission to enter that country when he gets permission from the immigration officials at the time of entry. Visa is either stamped in the passport or given as separate document.
