Citizenship in South Africa
Naturalisation timelines, tests, and dual nationality
Naturalisation generally requires permanent residence held for roughly five years, ordinary residence in South Africa for the year immediately preceding the application, good character, and a knowledge of the responsibilities of citizenship. The most consequential rule is at the other end: a South African who voluntarily acquires another nationality without first obtaining permission loses South African citizenship.
| Main route | Naturalisation under the South African Citizenship Act source |
| Qualifying period | Commonly roughly five years of permanent residence |
| Immediately preceding year | Ordinary residence in South Africa for the full year before applying |
| Spouses of citizens | Commonly around two years of permanent residence plus two years of marriage |
| Dual citizenship | Restricted: prior permission required before acquiring another nationality source |
Who qualifies to naturalise
- An applicant who has been lawfully admitted for permanent residence and has held that status for the prescribed qualifying period, commonly around five years.
- An applicant who was ordinarily resident in South Africa for the whole of the year immediately preceding the application.
- A spouse of a South African citizen, on a shorter qualifying period, commonly around two years of permanent residence combined with two years of marriage.
- A minor child of a permanent resident, on application by the parent, on a shorter basis.
- In each case the applicant must be of good character, intend to continue residing in South Africa, and be able to communicate in one of the official languages to the satisfaction of the Minister.
Citizenship by birth and descent
A child born in South Africa to at least one citizen or permanent resident parent is a citizen by birth, and there is a further provision for a person born in South Africa to non-citizen parents who has lived in the country until majority and whose birth was registered.
A child born outside South Africa to a South African parent acquires citizenship by descent, subject to registration of the birth. Registration is the practical hurdle, and unregistered births create difficulties years later.
The dual citizenship restriction
Under the Citizenship Act, an adult South African citizen who by a voluntary and formal act acquires the nationality of another country loses South African citizenship unless permission to retain it was obtained beforehand from the Minister. The permission is applied for before, not after, the other nationality is acquired.
The rule cuts one way only in practical terms: a foreigner naturalising as South African is not required by South African law to renounce a prior nationality, though the other country's law may require it. The provision has been the subject of litigation and its scope has been tested in the courts, so the current position should be checked against the department's own published guidance.
Timelines
Naturalisation applications are lodged at a Home Affairs office and, like other categories, are subject to processing periods that commonly run well beyond the department's published targets. The certificate of naturalisation must be issued before a passport application can follow.
