1. National Regulations on Renunciation of Previous Citizenship in Singapore

• No Dual Citizenship Policy: Singapore strictly prohibits dual citizenship under Article 134 of the Singapore Constitution. Individuals who wish to become Singapore citizens must renounce their previous citizenship(s) as part of the naturalization process.
• Mandatory Requirement: Renunciation of previous citizenship is a mandatory step for applicants who have been approved for Singapore citizenship. Failure to complete this step will result in the revocation of the Singapore citizenship approval.
• Timeline: Once Singapore citizenship is granted, individuals are typically given a deadline (usually 3 to 6 months) to provide proof of renunciation of their previous citizenship.

2. General Costs Associated with Renunciation

The costs of renouncing citizenship vary depending on the country of the individual's previous citizenship. Below are some general considerations:

• Renunciation Fees: Most countries charge a fee for processing the renunciation of citizenship. For example:
  • India: SGD 50–100 (approx.) for renunciation of Indian citizenship.
  • Malaysia: RM 10 (approx. SGD 3) for renunciation of Malaysian citizenship.
  • United States: USD 2,350 (approx. SGD 3,200) for renunciation of U.S. citizenship.
• Document Translation and Notarization: If the renunciation documents are not in English, they must be translated and notarized. Translation costs in Singapore typically range from SGD 50–150 per document.
• Travel Costs: If the renunciation process requires in-person attendance at an embassy or consulate, individuals may incur travel expenses.

3. Standard Procedures for Renunciation of Previous Citizenship

The renunciation process generally involves the following steps:

Step 1: Obtain Approval for Singapore Citizenship

• Apply for Singapore citizenship through the Immigration and Checkpoints Authority (ICA).
• Once approved, you will receive an in-principle approval (IPA) letter, which will include instructions to renounce your previous citizenship.

Step 2: Contact the Embassy/Consulate of Your Previous Country

• Reach out to the embassy or consulate of your previous country in Singapore (or the nearest location) to understand the specific renunciation process.
• Obtain the necessary forms and a checklist of required documents.

Step 3: Prepare Required Documents

The required documents vary by country but typically include:

• A completed renunciation form.
• Your original passport and a copy.
• Birth certificate (if applicable).
• Proof of Singapore citizenship approval (IPA letter).
• Recent passport-sized photographs.
• Payment for the renunciation fee.

Step 4: Submit the Renunciation Application

• Submit the application in person or by mail, depending on the requirements of your previous country.
• Some countries may require an in-person interview or additional verification.

Step 5: Receive Renunciation Certificate

• Once the renunciation is processed, you will receive a certificate or official confirmation of renunciation. Processing times vary by country:
  • India: 1–2 months.
  • Malaysia: 1–3 months.
  • United States: 6–12 months.

Step 6: Submit Proof of Renunciation to ICA

• Submit the renunciation certificate or official confirmation to the ICA within the stipulated timeframe.
• ICA will verify the document and finalize your Singapore citizenship process.

4. Country-Specific Considerations

India

• Indian citizens must surrender their Indian passport after renunciation. A "Surrender Certificate" is issued, which must be submitted to ICA.
• Overseas Citizenship of India (OCI) status can be applied for after renunciation, allowing visa-free travel to India.

Malaysia

• Renunciation of Malaysian citizenship must be done in person at the Malaysian High Commission in Singapore or in Malaysia.
• Malaysian law requires individuals to complete Form K for renunciation.

United States

• Renouncing U.S. citizenship is a lengthy and expensive process. It requires an in-person appointment at a U.S. embassy or consulate.
• U.S. citizens are subject to an "exit tax" if they meet certain financial thresholds.

China

• Chinese citizens must renounce their citizenship through the Chinese embassy or consulate. China does not allow dual citizenship, so the process is relatively straightforward.

Philippines

• Filipinos who renounce their citizenship may apply for dual citizenship later under the Philippines' Dual Citizenship Law (Republic Act No. 9225), but this is not recognized by Singapore.

5. Important Notes and Tips

• Strict Deadlines: Ensure you complete the renunciation process within the timeframe specified by ICA. Extensions may be granted in exceptional cases but are not guaranteed.
• Impact on Family Members: If you have dependents, check how renunciation affects their citizenship or residency status in your previous country.
• Tax Implications: Renouncing citizenship may have tax implications, especially for countries like the U.S. that impose taxes on worldwide income.
• Loss of Benefits: Renunciation may result in the loss of benefits, such as pensions or healthcare, in your previous country.
• Keep Copies: Retain copies of all documents submitted and received during the renunciation process for future reference.
