Does Singapore Allow Dual Citizenship? What You Need to Know

One of the most common questions among Permanent Residents and new citizens is: does Singapore allow dual citizenship?

The answer is clear and strictly enforced by law. Singapore does not allow dual citizenship for adults. Anyone who becomes a Singapore citizen must commit fully to Singapore nationality.

This article explains Singapore’s dual citizenship policy, what happens if someone holds more than one citizenship, and what applicants should consider before applying for Singapore citizenship.

Singapore’s Official Position on Dual Citizenship

According to the Immigration & Checkpoints Authority (ICA), adult Singapore citizens are not allowed to hold dual or multiple citizenships.

If a Singapore citizen acquires citizenship of another country, they are required to renounce their Singapore citizenship as soon as possible.

This policy applies regardless of:

• Country of second citizenship
• Length of time holding the foreign nationality
• Whether the foreign country allows dual citizenship

Singapore’s stance is firm and consistently enforced.

What Happens If an Adult Singaporean Holds Dual Citizenship?

ICA actively monitors and investigates cases of dual or multiple citizenship.

If an adult Singapore citizen is found to be holding another nationality:

• They are required to renounce the foreign citizenship if they wish to retain Singapore citizenship
• If they fail to do so, they may be deprived of Singapore citizenship

Between 2019 and 2023, an average of about 1,600 adult Singaporeans per year either renounced or were stripped of Singapore citizenship due to holding multiple citizenships. This highlights how seriously the policy is taken.

Can Minors Hold Dual Citizenship in Singapore?

Children are treated differently.

A child may hold dual citizenship temporarily if:

• They acquired Singapore citizenship by descent
• They were born overseas and automatically acquired another nationality

However, this is only allowed up to a certain age.

Before adulthood, the individual must choose one citizenship and formally renounce the other.

Failure to do so can affect their citizenship status later.

Can a Singapore Citizen Be a Permanent Resident of Another Country?

Yes. Singapore does allow its citizens to be permanent residents of another country.

Holding foreign permanent residency is not the same as holding foreign citizenship and does not violate Singapore’s citizenship laws. The restriction applies only to citizenship, not residency.

Can You Renounce Singapore Citizenship Before Obtaining Another?

Yes. A Singapore citizen may choose to renounce their Singapore citizenship before acquiring another nationality, subject to ICA approval and administrative procedures.

Once renounced:

• CPF savings may be withdrawn subject to rules
• Singapore citizenship privileges are lost
• Re-acquiring citizenship later is extremely difficult

This decision should never be taken lightly.

Why Singapore Does Not Allow Dual Citizenship

Singapore’s policy is rooted in national principles such as:

• Clear national allegiance
• National Service obligations
• Long-term social cohesion
• Equal civic responsibilities

Citizenship in Singapore is viewed as a deep, long-term commitment, not a flexible legal status.

What This Means for PRs Planning to Apply for Citizenship

If you are a Singapore Permanent Resident considering citizenship, you should plan early and carefully.

Before applying, ask yourself:

• Are you prepared to renounce your existing nationality?
• How will this affect property ownership, inheritance, or travel rights in your home country?
• What are the implications for your children and family?

Understanding the dual citizenship restriction upfront prevents costly mistakes and emotional stress later.
