Saudi Arabian nationality law
Saudi nationality law, officially called the Saudi Arabian Citizenship System, is the law that determines who is a Saudi citizen. Foreigners are not given citizenship even if they meet the terms and conditions.

Original Saudis 
Anyone who was born or resided on Saudi Arabian land from 1332 Hijra – 1914 A.D. until 22/3/1345 Hijra provided that they did not acquire a foreign citizenship prior to this date.

A child born in Saudi Arabia to a non-Saudi father and a Saudi mother has the right to Saudi citizenship upon reaching the age of majority if they fulfill the following criteria:

 have permanent residency
 be fluent in Arabic
 the grandfather of the mother is Saudi

By descent 
Children born to a Saudi father or an unknown or stateless father and Saudi mother could be a Saudi citizen if the conditions are satisfied.

By marriage 
A foreign woman who marries a Saudi man has right to citizenship provided that she gives up her foreign citizenship. Saudi women who give up citizenship upon marriage to a foreign husband (the marriage should complete 10 years and should have three children) has the right to take up Saudi citizenship if she divorces or returns to Saudi Arabia. One can only apply for citizenship if he is mature. Additional conditions are in place before the government will recognize a marriage by a Saudi woman to a non-Saudi man and allow a citizenship application.

Saudis working in various sensitive occupations, as well as members of the royal family, are not allowed to marry foreigners at all.

By naturalization
