Singapore dual citizenship rules

Who Can Hold Dual Citizenship in Singapore?

Singapore has strict rules about dual citizenship. Generally, the country does not encourage citizens to hold multiple nationalities. However, there is one exception: children born abroad to at least one Singaporean parent may automatically hold both Singapore citizenship and their birth country's citizenship at birth.

This dual status is temporary. Children in this situation must make a choice when they reach adulthood.

When Must You Choose One Nationality?

If you were born with dual citizenship (Singapore and another country), you must renounce one citizenship by age 22. Here's what you need to know:

• You have until your 22nd birthday to decide which citizenship to keep
• If you don't choose, Singapore will automatically consider your citizenship renounced
• The process involves formal paperwork filed with Singapore's Immigration and Checkpoints Authority (ICA)
• Once you renounce Singapore citizenship, the decision is permanent and difficult to reverse

How to Renounce Singapore Citizenship

If you decide to keep your other nationality:

• Contact the ICA or your nearest Singapore embassy or consulate
• Complete the required renunciation forms
• Provide identity documents and proof of your other citizenship
• Pay any applicable administrative fees
• Receive official confirmation of renunciation

The exact process and required documents vary by situation. Check the official ICA website for current procedures and forms specific to your case.

Can Adults Become Dual Citizens?

No. If you are an adult without dual citizenship at birth, Singapore will not allow you to hold multiple nationalities. You must choose Singapore citizenship or another country's citizenship—not both.

If you're a foreign national seeking to become a Singapore citizen, you may need to renounce your original nationality as part of the naturalization process, depending on your home country's laws.

Important Considerations

Before your 22nd birthday, think carefully about which citizenship to keep:

• Residency rights: Which country do you plan to live in?
• Work opportunities: Which passport opens more job options for you?
• Military service: Some countries require military service from male citizens
• Taxes: Different countries have different tax obligations
• Family ties: Where are your family members based?
