South African Citizenship: How to Apply [2026]

South African citizenship is more than a passport. It determines whether you can vote, hold an SA-issued 13-digit ID number, work without a permit, and pass nationality on to your children. Most people in South Africa are citizens by birth and rarely think about it. For everyone else — naturalisation applicants, the children of South Africans born abroad, spouses of citizens, dual nationals — the rules in the South African Citizenship Act 88 of 1995 matter a great deal.

This guide walks through the four legal routes to citizenship, the dual-citizenship retention rule that catches thousands of South Africans abroad, the documents and fees you'll need at Home Affairs in 2026, and the most common reasons applications get rejected.

What South African citizenship actually means

The Citizenship Act sets out three legal categories: citizenship by birth, citizenship by descent, and citizenship by naturalisation. Marriage is not a separate category — it's a faster naturalisation route. A person can hold any one of these statuses; the practical effect is identical (full citizenship rights, including a passport and the right to live and work in South Africa indefinitely).

South African citizens get a 13-digit ID number where the 11th digit is 0. Permanent residents — not citizens — get the same 13-digit format with an 11th digit of 1. If you're not sure where you stand, our guide to non-citizen ID numbers in South Africa covers the differences in detail.

1. Citizenship by birth

You are a South African citizen by birth if any of the following applied at the moment of your birth:

• You were born in South Africa AND at least one of your parents was a South African citizen or permanent resident at the time.
• You were born in South Africa AND were not granted citizenship of any other country at birth (this provision protects against statelessness — Section 2(2)).
• You were born in South Africa AND have lived in South Africa from birth to the age of 18, with your birth properly registered under the Births and Deaths Registration Act (a 2010 amendment, used by children of foreign nationals who never acquired any other nationality).

You don't apply for citizenship by birth — it's automatic. You do, however, need a properly registered birth certificate to prove it. If your birth was never registered or was registered late, see our guide to late registration of birth in South Africa.

Adoption

A child adopted by a South African citizen under the Children's Act becomes a South African citizen by birth from the date of the adoption order, regardless of where the child was born or what nationality they held previously.

2. Citizenship by descent

A person is a citizen by descent if they were born outside South Africa to at least one South African citizen parent, and the birth has been registered with the South African Department of Home Affairs.

The registration is the critical step. South African embassies and high commissions accept applications on behalf of DHA using Form BI-24 (Notice of Birth) together with the foreign birth certificate, the parents' SA ID/passport, and the parents' marriage certificate where applicable. Once registered, the child is issued a South African birth certificate and an unabridged ID number; from there they can apply for a passport and a Smart ID card on the same terms as a citizen by birth.

If you missed the registration window as a child, you can still apply as an adult — but the process becomes longer because Home Affairs has to satisfy itself that you have a continuous biographical link to a South African citizen parent. Bring everything: the parent's birth certificate, ID, passport, school records, anything.

3. Citizenship by naturalisation

Naturalisation is the route taken by foreigners who have lived in South Africa long enough on a Permanent Residence permit to qualify for full citizenship. Section 5 of the Citizenship Act sets out the requirements:

• You hold a valid Permanent Residence permit issued under the Immigration Act.
• You have been ordinarily resident in South Africa for the period immediately before applying — five years of continuous residence as a permanent resident, plus at least one year of physical residence in South Africa during the year before you apply.
• You are of good character (no serious criminal convictions, no fraud history, no concealed prior nationality).
• You can communicate in any one of the eleven official South African languages to the satisfaction of the Minister.
• You have an adequate knowledge of the responsibilities of citizenship.
• You intend to continue residing in South Africa or to enter or continue in service of the South African government.

The application uses Form BI-1664, lodged at a Home Affairs office that handles citizenship applications. You'll need:

• Original PR certificate and proof of continuous residence (passport stamps, employer letters, lease agreements, bank statements).
• Police clearance from every country you've lived in for 12 months or more after the age of 18.
• A South African medical and radiological certificate.
• Proof of payment of the prescribed fee (R300 in 2026).
• Two recent passport photos.
• Affidavits affirming the language and citizenship-knowledge requirements.

If approved, you'll attend a citizenship ceremony where you take the oath of allegiance. Only after the oath is recorded does your citizenship take effect — the certificate (Form BI-37) is issued in your name from that date. You can then apply for a Smart ID card and a South African passport.

Naturalisation timeline in 2026

Realistic processing times for naturalisation applications are 18 to 36 months. The Minister of Home Affairs personally signs each citizenship grant, which means the file moves through head office in Pretoria, not your local DHA branch. Applications that include strong, well-organised supporting documents move faster than thin files that have to go back for verification.

Naturalisation requirements at a glance

To qualify for South African citizenship by naturalisation under Section 5, you must meet all of the following:

4. Citizenship by marriage

Marriage to a South African citizen does not, on its own, confer citizenship. It does, however, create a faster naturalisation route. Under Section 5(5) of the Citizenship Act, the spouse of an SA citizen may apply for naturalisation after two years of marriage and two years of permanent residence — instead of the standard five-year continuous-residence rule.

You'll still need:

• A valid PR permit (the spousal visa is not the same thing — you must convert to PR first, typically through a Section 26(b) application after five years of marriage).
• Proof of subsisting marriage (an unabridged marriage certificate, joint accounts, joint lease).
• The same Form BI-1664, supporting documents, language and good-character evidence as a standard naturalisation applicant.

The two-year shortcut runs from the date you became a permanent resident, not from the wedding date. A foreign spouse who has lived in South Africa for ten years on a spousal visa but only switched to PR last year still has to wait one more year before applying.

5. Dual citizenship and Section 6 retention

This is where most South Africans abroad come unstuck. Dual citizenship is permitted under South African law, but only if you follow the procedure in Section 6 of the Citizenship Act.

The rule, in plain English: if you are an SA citizen and you intend to acquire another country's citizenship by a voluntary and formal act (most naturalisation processes qualify), you must apply for and receive a retention certificate from the Department of Home Affairs before taking on the foreign citizenship. If you don't, you automatically lose your South African citizenship the moment you become a citizen of the other country.

The retention application uses Form BI-1664 (the same form as naturalisation, ticked for retention). You can lodge it at any South African embassy or high commission, or in person at DHA in South Africa. The fee is around R600 in 2026 and the certificate typically takes 6–12 months to issue.

Children of dual citizens

Section 6 only applies to a person who voluntarily acquires foreign citizenship after 18. A South African child who acquires another nationality automatically by descent (because one parent is a foreign national) is not affected — the child remains South African unless they later renounce.

What if I already lost my SA citizenship?

The Constitutional Court in Democratic Alliance v Minister of Home Affairs (2024) reaffirmed that Section 6 is constitutional. People who lost their citizenship by failing to apply for retention have to apply for resumption under Section 13 — they don't get an automatic restoration. Resumption is at the Minister's discretion, requires PR or a return to South Africa, and can take years. The Citizenship Amendment Bill currently before Parliament may relax these rules; until it passes, the safe move is to apply for retention before naturalising abroad.

Loss of citizenship

Section 7 lists the ways a South African can lose citizenship:

• Voluntarily acquiring the citizenship of another country without first obtaining a retention certificate.
• Serving in the armed forces of a country at war with South Africa.
• Formal renunciation under Section 7(2) — typically requested by countries that don't allow dual citizenship from their naturalisation candidates.
• Deprivation by the Minister where citizenship was obtained by fraud, false representation, or concealment of a material fact (Section 8).

Loss of citizenship is recorded on the National Population Register. If you're not sure of your status, ask DHA to confirm in writing — don't rely on a passport that may have been issued in error.

Documents you'll need

The exact list depends on which route you're applying under. The common core is:

• Original birth certificate (full unabridged version).
• Original ID document (if applicable) or current passport.
• Permanent Residence certificate (BI-947) for naturalisation and marriage routes.
• Marriage certificate or proof of relationship for spousal applicants.
• Police clearance certificates from every country of 12-month residence after age 18.
• Two recent passport-style photographs.
• Bank statements or payslips covering the residence period.
• SAPS-stamped fingerprints (taken at any branch).
• Proof of fee payment.

You can find the official form set on the Department of Home Affairs website at dha.gov.za and the full Citizenship Act on the government legislation portal.

How to apply for South African citizenship: step by step

Whichever route you qualify under, a naturalisation or marriage-route application runs through the Department of Home Affairs and ends with the Minister. Here is the process from start to finish:

1. Confirm your route and eligibility. Check that you meet the Section 5 requirements above — most importantly five years of permanent residence, or two years' PR plus two years of marriage to a South African citizen. Citizens by descent follow the Form BI-24 birth-registration route instead.
2. Gather your documents. Assemble the full set listed below — PR certificate, police clearances, proof of continuous residence, photographs and fingerprints. Thin, poorly organised files are the single biggest cause of delay.
3. Complete Form BI-1664. This is the application for naturalisation (the same form covers retention, renunciation and resumption). Download it from dha.gov.za or collect it at a Home Affairs office that handles citizenship.
4. Book a Home Affairs appointment. Not every branch processes citizenship applications — confirm first through the Home Affairs online services hub or by calling ahead.
5. Submit and pay. Lodge the form in person with your supporting documents and pay the R300 application fee. Keep the receipt.
6. Give SAPS fingerprints. Your prints are taken for the good-character and security checks.
7. Wait for the ministerial decision. The Minister of Home Affairs personally signs each grant, so the file moves through head office in Pretoria. Realistic timelines run 18 to 36 months.
8. Attend the citizenship ceremony. If approved, you take the oath of allegiance. Your citizenship takes effect only once the oath is recorded and the certificate (Form BI-37) is issued in your name.
9. Apply for your Smart ID and passport. Within six to twelve weeks of the certificate you can apply for a Smart ID card and passport on the same terms as a citizen by birth — your new ID number's 11th digit will be 0.

You can confirm the structure of that new number on our free SA ID validator before you start using it on banking, tax and employment forms.

How to verify a South African ID after citizenship is granted

After your citizenship is approved, Home Affairs issues a citizenship certificate (BI-37) and adds you to the National Population Register. Within 6–12 weeks you can apply for a Smart ID card and a passport on the same terms as a citizen by birth. Your new ID number's 11th digit will be 0 (citizen), not 1 (permanent resident).

You can do a basic structural check of the new number on our free SA ID validator — it confirms the Luhn checksum, decodes the date of birth, gender, and citizenship status, and flags any obvious errors before you start using the number on banking, employment, and tax forms.

Common reasons citizenship applications are rejected

• Continuous-residence gaps. Applicants who spent extended time outside South Africa during the qualifying period — even on legitimate work assignments — often see refusals because Section 5 requires "ordinary residence". Document every absence.
• Police-clearance shortfalls. Forgetting a country where you spent more than 12 months after age 18 is the most common technical reason for delay.
• Inadequate language proof. The language assessment is rarely formal but it has to be evidenced — a sworn affidavit, employer letter, or interview note.
• PR irregularities. If your PR was issued on a basis you no longer satisfy (a critical-skills permit you've left the field of, a spousal PR after a divorce), the file gets flagged.
• Voluntary foreign citizenship before retention. If you've already taken on another nationality without a Section 6 certificate, your file isn't a naturalisation application — it's a Section 13 resumption, which is much harder.

The Citizenship Amendment Bill (B7-2024)

Parliament is currently considering a Citizenship Amendment Bill that would reform Section 6 (retention) and Section 8 (deprivation), and add new categories for stateless children born in South Africa. If passed, the most significant change for South Africans abroad would be a default-retention rule — you'd keep SA citizenship unless you explicitly renounce. The Bill has not been signed into law as of May 2026, so the existing Section 6 rule still applies. Watch the Department of Home Affairs and Parliament websites for updates before relying on any change.

Frequently asked questions

How do I apply for South African citizenship?

Complete Form BI-1664, the naturalisation application, and gather your supporting documents — permanent residence certificate, police clearances, proof of continuous residence, photographs and fingerprints. Lodge it in person at a Home Affairs office that handles citizenship applications and pay the R300 fee. The file goes to head office in Pretoria for the Minister's decision, which takes 18 to 36 months, after which you attend a citizenship ceremony and take the oath of allegiance. Citizens by descent register a foreign birth on Form BI-24 instead.

What are the requirements for South African citizenship by naturalisation?

You need a valid permanent residence permit, five years of continuous ordinary residence as a permanent resident (or two years' PR plus two years of marriage to a citizen), at least one year of physical residence in the 12 months before applying, good character backed by police clearances, the ability to communicate in one of South Africa's official languages, and an intention to keep living in South Africa. All are set out in Section 5 of the Citizenship Act 88 of 1995.

How long do I have to live in South Africa before I can apply for citizenship?

Five years of continuous permanent residence, plus at least one year of physical residence in South Africa in the 12 months before you apply. The five-year clock runs from the date you became a permanent resident, not from the date you arrived in the country. Spouses of South African citizens qualify after two years of PR plus two years of marriage.

Can I have South African citizenship and another nationality?

Yes. South African law permits dual citizenship if you follow the Section 6 retention procedure: apply for a retention certificate before you formally acquire the other country's citizenship. If you take the other citizenship first, you automatically lose your SA citizenship under the Citizenship Act. The retention certificate, once issued, is permanent and does not need to be renewed.

Does marrying a South African citizen automatically make me a citizen?

No. Marriage entitles you to a spousal visa and, eventually, a permanent residence permit; you still have to apply for citizenship by naturalisation under Section 5(5). The marriage route shortens the residence requirement to two years of PR plus two years of marriage, but the application process and Form BI-1664 are the same as standard naturalisation.

I was born outside South Africa to South African parents. Am I automatically a citizen?

You qualify for citizenship by descent, but you have to be registered with the Department of Home Affairs (Form BI-24) for the citizenship to be effective. Until your foreign birth is registered with DHA, you cannot get a South African passport or ID number even if both parents are SA citizens. Apply at the nearest South African embassy or high commission.

How much does it cost to apply for South African citizenship in 2026?

The Form BI-1664 application fee is R300. Retention of SA citizenship is R600. Birth registration for citizenship by descent is R75. Embassies abroad charge a foreign-currency equivalent that's updated twice a year. Add the cost of police clearances, sworn translations, and travel — most applicants budget R3,000–R8,000 in total.

I lost my South African citizenship years ago by naturalising abroad without a retention certificate. Can I get it back?

Yes, but the route is Section 13 resumption, not a fresh citizenship application. You typically have to take up permanent residence in South Africa again, lodge a Form BI-1664 marked for resumption, and wait for a ministerial decision. Resumption is at the Minister's discretion, takes 12–24 months, and is not guaranteed. The pending Citizenship Amendment Bill may simplify this — track the Bill before applying.
