The Constitution sets out who is a Kenyan citizen, how citizenship is acquired, and the rights that come with it — including the right to a passport and documents, and the ability to hold dual citizenship.
Article 12; Article 16; Articles 12–18; Chapter Three
You are a Kenyan citizen by birth if, on the day you were born, either your mother or your father was a Kenyan citizen — whether you were born inside or outside Kenya.
People who are not citizens by birth can become citizens by registration — for example, after being married to a Kenyan for a set period, or after lawfully living in Kenya long enough.
Kenyans who are citizens by birth are allowed to hold the citizenship of another country at the same time — dual citizenship — without losing their Kenyan citizenship.
Your Identity Documents: ID, Birth and Death Registration
Citizenship comes with documents — a birth certificate, a national ID at adulthood, and a passport. These prove who you are and unlock services, voting and travel.
