# Naturalisation certificates and dual citizenship: status for emigrants

If you’ve emigrated – or you’re planning to – you may suddenly find yourself dealing with **naturalisation certificates**, **dual citizenship rules**, and questions like: *“Am I still a South African citizen if I take another passport?”*

South Africa’s citizenship rules have also changed recently, especially around automatic loss of citizenship when taking another nationality, so it’s more important than ever to understand what your documents mean and when you might need them.

While Apostil.co.za doesn’t give legal advice or decide anyone’s status, we *do* help emigrants get the **proof of status** they need – naturalisation certificates, unabridged birth records, apostilles and more – so they can deal confidently with foreign authorities.

For your broader move, you can start here:

## **What is a South African naturalisation certificate?**

A **naturalisation certificate** is the formal document issued to someone who has been **granted South African citizenship by naturalisation**, rather than by birth or descent.

It normally confirms:

- Your full personal details
- The date you were naturalised
- The legal basis under which naturalisation was granted
- An official reference number and issuing authority

In practice, this certificate is often needed when you:

- Apply for **passports** or ID after a long time abroad
- Prove your status to **foreign immigration authorities**
- Claim **citizenship by descent** for your children
- Deal with **South African Home Affairs** after system changes or data errors

If you no longer have your original document, you may need a **replacement or confirmation of naturalisation** from Home Affairs. Apostil.co.za can help with retrieving these types of civic records and preparing them for overseas use.

## **Naturalisation vs citizenship by birth or descent**

It’s useful to distinguish:

- **Citizenship by birth** – usually where you were born in South Africa and met the legal requirements at the time.
- **Citizenship by descent** – often where you were born abroad to South African parents.
- **Citizenship by naturalisation** – where you met residence and other criteria and *applied* to become a South African citizen.

Foreign authorities may treat these categories differently, especially when you:

- Apply for **dual citizenship**
- Register children’s births abroad
- Apply for **ancestry-based visas**

That’s why they may specifically ask to see a **naturalisation certificate** (if that’s how you became South African) *together with* your unabridged birth certificate and other civic records.

## **Dual citizenship: what has changed?**

For many years, South Africans who **voluntarily acquired a foreign citizenship** (for example by naturalising in the UK, Australia, Canada, etc.) could **automatically lose their South African citizenship** if they did not first apply for formal **retention of South African citizenship** in terms of section 6(1)(a) of the Citizenship Act.

That meant:

- You applied for another citizenship without getting retention.
- By operation of law, you were treated as having **lost** South African citizenship on the day you acquired the new one.
- Many people only discovered this when they tried to renew a South African passport years later.

### **The court decisions**

- In **June 2023**, the Supreme Court of Appeal held that this automatic loss provision (section 6(1)(a)) was **unconstitutional**, and that those who had lost citizenship under it were **deemed not to have lost it**.
- On **6 May 2025**, the **Constitutional Court** confirmed this invalidity and the order that affected citizens are deemed never to have lost their South African citizenship.

In plain English:

- The automatic loss rule has been struck down.
- People who previously “lost” citizenship under that rule are, in law, treated as if they **never lost it**.

The Department of Home Affairs has indicated it is developing systems so affected South Africans can **confirm their reinstated citizenship**, including from abroad.

## **Where “retention of citizenship” still fits in**

Even though section 6(1)(a) has been declared invalid, the concept of **retention of South African citizenship** remains important, because:

- Foreign lawyers, consulates and older website guidance may still refer to the *previous* rules.
- Banks and institutions in South Africa may still ask for evidence that your citizenship has not been lost.
- Administrative systems at Home Affairs will take time to catch up with court rulings.

Apostil.co.za explains retention and its practical impact here:
👉[**Retention of South African citizenship**](https://apostil.co.za/retention-of-south-african-citizenship/?utm_source=chatgpt.com)

If you previously applied for retention and have mislaid the letter, you may want to **retrieve a copy** or obtain supporting documentation, especially if a foreign authority insists on it despite the changed legal position.

## **How naturalisation certificates interact with dual citizenship**

If you are a **naturalised South African who later emigrates and acquires another citizenship**, your document trail might include:

- Your **South African naturalisation certificate**
- Your **unabridged birth certificate** (from your country of birth)
- Your **foreign naturalisation certificate** from the new country
- Possibly a **retention letter** (if you previously applied for one)

Foreign and South African authorities may use these documents to:

- Confirm **how** and **when** you became South African
- Confirm that you **held South African citizenship** at the time you passed it on to your children
- Determine whether you qualify for certain **visas, passports or citizenship claims**

In some cases, you may need to have your **South African naturalisation certificate apostilled** or authenticated for use abroad:

## **Typical situations for emigrants**

Here are a few common scenarios where Apostil.co.za clients need help:

1. **You’re a naturalised South African, now acquiring foreign citizenship**
   - You may want to show clearly that you **remain South African**, especially during the transition after the court rulings.
   - Your naturalisation certificate and other records may need to be apostilled.
2. **You were told in the past that you’d “lost” South African citizenship**
   - Under the recent Constitutional Court confirmation, you are now **deemed not to have lost it**, but you may need documentation to prove this in practice.
   - You may want to gather your naturalisation/birth certificates and keep them ready for any Home Affairs verification processes.
3. **You’re applying for citizenship by descent for your children abroad**
   - You may have to show your own **naturalisation certificate or birth certificate**, your children’s unabridged birth certificates, and sometimes police clearances or other supporting documents.

- Retrieving **naturalisation records** and other civic certificates from Home Affairs where possible
- Obtaining **unabridged birth and marriage certificates** needed for citizenship and visa cases
- Arranging **apostilles and authentications** for use in any Hague or non-Hague country

Naturalisation certificates and dual citizenship are no longer just abstract legal concepts – they sit at the heart of how emigrants **prove their identity, protect their rights and manage life in more than one country**. With the old automatic-loss rule now struck down, many South Africans abroad are in a better position than they realise, but they still need the right paperwork in hand.

If you’re unsure which certificates you need, or you’re abroad and battling to get anything out of Home Affairs, you don’t have to do it alone.
