Eligibility for Saudi citizenship:
* By descent: A child born to a Saudi father is automatically a Saudi citizen. A child born to a Saudi mother and a non-Saudi father may also be eligible for Saudi citizenship if the father is a national of a country that has a reciprocal agreement with Saudi Arabia.
* By naturalization: Foreign nationals may apply for Saudi citizenship after meeting certain requirements, including having lived in Saudi Arabia for a specified period of time, speaking Arabic, and having no criminal record.
* By royal decree: The King of Saudi Arabia may grant Saudi citizenship to individuals who have made exceptional contributions to the country.
Loss of Saudi citizenship:
* Voluntary renunciation: A Saudi citizen may renounce their citizenship by submitting a written request to the Ministry of Interior.
* Involuntary revocation: The Ministry of Interior may revoke Saudi citizenship from individuals who have committed certain offenses, such as espionage, treason, or terrorism.
Dual citizenship:
* Saudi Arabia does not recognize dual citizenship. This means that Saudi citizens who acquire citizenship of another country will automatically lose their Saudi citizenship.
