Passport Act Article 14

Diplomatic and official passports are issued free of charge. Fees shall be charged for ordinary passports unless they are issued for official purposes as approved by the Competent Authority. However, in the event that, within three months of issuance of the passport, the Competent Authority agrees to reissue the passport in accordance with Subparagraph 3 of Paragraph 2 of Article 19 due to inauspicious homophones appearing in the passport number or other special circumstances, the fees may be reduced. Fee standards shall be prescribed by the Competent Authority.
