How to Become a South African Citizen: Naturalization and Documents

To become a South African citizen, you generally follow one of three routes: citizenship by birth or descent through a South African parent, naturalization after five years of permanent residence, or naturalization based on two years of marriage to a South African citizen. All three run through the Department of Home Affairs (DHA) under the South African Citizenship Act of 1995.¹ Which route fits you depends on your family, your immigration history, and how long you have already been in the country.

Naturalization: The Main Route for Foreign Nationals

Naturalization is how most foreign nationals become South African citizens. It is not fast, and every requirement has to be met before the DHA will consider the application. You must:

Hold permanent residence in South Africa before applying.
Have lived in South Africa continuously for at least five years immediately before your application date.
Be 18 or older.
Satisfy the Minister of Home Affairs that you are of good character.
Communicate in at least one of South Africa’s 12 official languages.
Show adequate knowledge of the responsibilities and privileges of citizenship.
Intend to keep living in South Africa, or be serving the South African government or an international organization of which South Africa is a member.
Renounce your existing citizenship if your home country does not allow dual citizenship, and provide proof of that renunciation.²

The five-year clock catches people out. The statute requires five continuous years immediately before you apply, so significant time abroad can reset the count. If you travel frequently for work, keep careful records of your dates in and out of the country.

Naturalization Through Marriage

Marrying a South African does not, by itself, make you one. Section 14 of the Citizenship Act is explicit on that point.² The marriage pathway is naturalization with a shorter residency requirement. You need permanent residence, at least two consecutive years of living in South Africa after the marriage, and the marriage must still be in place across that period.³ The good-character requirement applies here too.

The two years run from the date of marriage, but you also have to be ordinarily resident in South Africa during that period. If you married abroad and then relocated, the clock effectively starts on arrival. Because permanent residence is a prerequisite, factor in the time needed to secure it before the citizenship timeline even begins.

Citizenship by Birth or Descent

If one of your parents was a South African citizen when you were born, you are a South African citizen by birth no matter where in the world that happened.² For births outside South Africa, citizenship only takes effect once the birth is registered with South African authorities, either at a DHA office or through a South African embassy or consulate.⁴

Children born in South Africa to non-citizen parents sit in a more restrictive space. If both parents are permanent residents, the child qualifies for citizenship by birth on turning 18, provided they have lived in South Africa continuously since birth and their birth was registered.² Where neither parent is a citizen or permanent resident, the child can apply on reaching 18 under a separate provision, again with lifelong residence and a registered birth.

One safeguard sits above these rules. A child born in South Africa who would otherwise have no citizenship or nationality of any country, and whose birth is registered, is a South African citizen by birth. The purpose is to prevent statelessness, though the registration requirement can itself be a barrier.

Documents You Will Need

Requirements vary by route, but most applications draw on the same core set. Start gathering these early; certification and translation take longer than most applicants expect.

A valid passport, and any South African non-citizen ID you already hold.
Original or certified copies of your birth certificate and, where relevant, marriage certificate.
Your permanent residence certificate (for naturalization and the marriage route).
Police clearance certificates from the South African Police Service and from every other country where you hold or have held citizenship.
The correct application form: DHA-529 for determination of citizenship status, or DHA-63 for naturalization, both available from DHA offices and South African missions abroad.⁵
Certified translations of any document not in one of South Africa’s official languages.

All copies must be certified. Forms should be completed in block letters using black ink; the DHA is strict about incomplete or illegible submissions. If you are registering a birth abroad for citizenship by descent, you work through the nearest South African embassy or consulate rather than a domestic DHA office.

Where and How to Apply

Naturalization applications have to be filed in person at a DHA office inside South Africa.⁶ You cannot file for naturalization from abroad. Applications for citizenship by descent or for a determination of citizenship status can be submitted through South African embassies and consulates in your country of residence.⁷

A non-refundable fee is due at submission. Amounts vary by application type and by whether you file domestically or through a consulate, and they are updated from time to time, so confirm the current figure with the office handling your case. Keep the payment receipt; the DHA will not process the application without it. You should also receive a receipt or tracking number when you submit, and that number is your main tool for following up.

The Interview

Naturalization applicants can expect a personal interview with a DHA officer covering eligibility, language ability, and knowledge of South African civic life. Some applicants are also asked to take a separate language or cultural knowledge test. There is no published study guide. In practice, the threshold is being able to hold a conversation in one of the official languages and to understand basic civic concepts such as voting rights and the structure of government.

Processing Times and the Ceremony

South African citizenship applications are slow. The DHA’s own published estimates for citizenship determination sit at six to nine months as of 2025.⁸ Naturalization applications often take as long or longer, especially when the DHA requests further documents or schedules follow-up interviews. Background checks are standard.

While you wait, the DHA may contact you for additional information or clarifications. Respond quickly; delays on your end extend the whole timeline. Tracking systems exist but their reliability varies by office.

If approved, you will be notified in writing and invited to a citizenship ceremony. There you take an oath of allegiance and receive your Certificate of Naturalisation. The ceremony is a legal requirement for naturalization, not a formality you can skip.

Dual Citizenship

Whether you can keep your original citizenship depends on your home country’s rules, not South Africa’s alone. South African law requires renunciation only where the other country forbids dual citizenship.² If your country permits dual citizenship, you can hold both.

For South Africans acquiring a foreign citizenship, the picture also changed in 2025. On 6 May 2025 the Constitutional Court declared Section 6(1)(a) of the Citizenship Act unconstitutional in Democratic Alliance v Minister of Home Affairs, ending the old rule that stripped South Africans of citizenship automatically when they took up another nationality without a prior retention certificate.⁹ Retention applications are no longer needed.

If Your Application Is Denied

A denial is not necessarily the end. The DHA must give written reasons, and those reasons shape what you do next. Two options are open to you.

You can apply for judicial review in the High Court under the Promotion of Administrative Justice Act (PAJA). That is the route if you believe the DHA made a procedural error, acted unreasonably, or took an irrationally long time to decide. The deadline for filing is six months from the date you receive the rejection notice.

Alternatively, if the denial rested on a fixable issue such as missing documents or an unmet residency requirement, you can reapply. You must wait 12 months from the date of the refusal before submitting a new application. Use that time to address whatever caused the denial.

After Approval: ID and Passport

A Certificate of Naturalisation on its own does not let you travel or access government services. For that you need a South African identity document, and, if you intend to travel internationally, a passport. The smart ID card has replaced the old green ID book, and you apply for it at a DHA office.

You must have your South African ID before you can apply for a passport.¹⁰ Some DHA offices now use an online appointment system, so check whether your nearest office requires a booking. Both the ID and the passport are handled separately from your citizenship application, and each has its own queue, so build in additional time for these final steps before you can consider the process complete.
