A Singapore Permanent Resident who has held PR status for at least two years and is aged 21 or above can apply for Singapore citizenship online through ICA, without a sponsor. ICA says it generally processes applications within 12 months and assesses factors such as family ties to Singaporeans, economic contribution, qualifications, age, family profile and length of residence. If approved, adults must renounce their foreign citizenship before taking the Oath of Renunciation, Allegiance and Loyalty. Your company, shareholding and directorships are not affected by the change, but your family’s National Service position, property costs and travel arrangements are.
Raffles Corporate Services works with a panel of experienced Singapore law firms who offer cost-effective and efficient legal service and advice. This article is general information only and is not legal advice.
This guide is written for PRs who run or own a Singapore company, or who hold senior roles in one, and who are now weighing whether to take the next step. It covers who can apply, how the application and the stages after approval work, what changes for you and your business, and the questions worth settling before you submit.
Who can apply for Singapore citizenship?
ICA lists several eligibility routes on its Singapore citizenship page. For most business owners and professionals, the first route is the relevant one.
| Applicant | ICA’s stated requirement | Sponsor |
|---|---|---|
| PR applying in your own right | PR for at least 2 years and aged 21 and above | None |
| PR married to a Singapore Citizen | PR for at least 2 years and married to the Singapore Citizen for at least 2 years | Your Singapore Citizen spouse |
| PR student in Singapore | Resided in Singapore for more than 3 years, at least 1 of them as a PR, and passed a national exam or in the Integrated Programme | None (parental consent if under 21) |
| Aged parent of a Singapore Citizen | PR and parent of a Singapore Citizen aged 21 and above | Your Singapore Citizen child |
| Unmarried child under 21 of a Singapore Citizen | Born within a legal marriage to, or legally adopted by, a Singapore Citizen | The Singapore Citizen parent |
Meeting the eligibility rule only lets you apply. It is not a test that guarantees approval. ICA assesses each application against its stated factors, which it uses to judge your ability to contribute, to integrate into Singapore society and your commitment to sinking roots here.
What does ICA look at when assessing an application?
ICA states that it considers family ties to Singaporeans, economic contributions, qualifications, age, family profile and length of residency. It does not publish a points table or weighting, and nobody outside ICA can tell you the score you need.
For a business owner, “economic contribution” is usually shown through documents rather than claims. Practical points to check before applying:
- Consistent income records. If you pay yourself a salary and dividends from your own company, the figures in your payslips, IRAS notices of assessment and company accounts should agree. Our guide to PR for business owners and company directors explains how salary, dividends and company records are read together.
- An up-to-date company file. Annual returns, financial statements and tax filings should be current. Gaps invite questions.
- Your residence pattern. Long periods spent abroad do not disqualify you by themselves, but they are part of the picture of where your life is based.
- Family position. Whether your spouse and children are also PRs or citizens, and whether they are applying with you.
How do you apply, step by step?
- Check male family members’ National Service position first. ICA asks all male applicants to read the information at cmpb.gov.sg before applying. More on this below.
- Download ICA’s document checklist from the citizenship page and gather each document. Documents not in English need official translations; ICA accepts translations by the issuing country’s embassy or a notary public.
- Log in to the ICA e-Service with Singpass. If you apply without a sponsor, you complete the form, make your declarations and submit. If a spouse or child sponsors you, the sponsor completes the form and you log in to review it and make your own declarations before it is submitted.
- Pay the submission fee. ICA lists S$100 per applicant for adult PRs at submission. Fees are not refundable.
- Respond promptly to any ICA request for further documents during processing.
- Wait for the outcome. ICA says applications are generally processed within 12 months.
One detail that catches business owners: ICA requires the employment letter to be dated within 3 months of the application and addressed to the ICA Services Centre. If your own company is issuing the letter, make sure its salary, role and start date match your payroll, CPF and IRAS records exactly.
Documents checklist for a business owner applicant
ICA’s checklist is the authority, and you should follow the current version. A PR who owns or runs a company should also have the following ready so that what is submitted is consistent:
- Passport, NRIC and existing PR documents
- Marriage and birth certificates for family members included, with official translations where needed
- Employment letter dated within 3 months, addressed to the ICA Services Centre
- Recent payslips and IRAS notices of assessment
- Your company’s latest financial statements and ACRA business profile, if your income depends on the company
- Educational certificates
What happens after In-Principle Approval?
An approval is first given in principle. ICA’s page on completion of formalities sets out what follows. You become a citizen only after every step is done.
- Complete the e-Service tasks. Submit the required documents and photographs.
- Pay the issuance fees by the deadline. ICA lists S$70 for the citizenship certificate and S$10 for the identity card. Missing the payment deadline can lead to the application being withdrawn.
- Download your Final Outcome Letter. Do not start renouncing your foreign citizenship before this point. The letter is valid for 6 months.
- Renounce your foreign citizenship (applicants aged 21 and above) with your home country’s authorities, and upload the renunciation documents.
- Complete the Singapore Citizenship Journey if you are aged 16 to 60. ICA makes this programme mandatory before you complete the identity card formalities.
- Attend the ICA appointment stated in your letter, where adults take the Oath of Renunciation, Allegiance and Loyalty.
- After the grant, apply for your passport, collect your identity card and, if your home country requires it, submit proof of final renunciation within 15 months of the grant.
- Attend the citizenship ceremony, where you receive your certificate. ICA says this is held about 6 months after the grant.
Singapore does not allow adults to keep a second citizenship after becoming Singapore citizens. Children granted citizenship under 21 may hold more than one citizenship until 21, but must renounce the other and take the oath before turning 22, or they lose Singapore citizenship on their 22nd birthday. Check with your home country how long its renunciation process takes, because some take months.
What about National Service for sons?
National Service is often the deciding issue for families with sons. ICA states that male applicants granted citizenship or PR must register for NS at 16 and a half and are enlisted at the earliest opportunity after turning 18, or after pre-tertiary studies if later. MINDEF does not defer enlistment for university studies. Defaulting is an offence, with ICA citing a fine of up to S$10,000, imprisonment of up to 3 years, or both.
Sons who became PRs under their parents’ sponsorship are generally already liable, so citizenship may not change their position. Read the CMPB guidance for each son’s circumstances before deciding the family’s applications.
What changes for you and your company?
| Area | As a PR | As a citizen |
|---|---|---|
| Company ownership and directorships | No restriction; counts as a locally resident director | No change |
| CPF contributions on your salary | Full rates from the third year of PR | Full rates; no change if already past year two |
| ABSD on residential property (purchases from 27 April 2023) | 5% first, 30% second, 35% third and later | 0% first, 20% second, 30% third and later |
| Leaving Singapore | Valid Re-Entry Permit needed to keep PR status abroad | No Re-Entry Permit |
| Other citizenship | Can keep it | Adults must renounce it |
The ABSD rates come from the IRAS ABSD page, and the rate depends on your status on the date of purchase, so timing a property purchase around the grant date matters. The CPF position follows the CPF Board’s contribution rules, under which PRs move to full rates from their third year. Your company should update your residency status in its HR and payroll records once citizenship is granted. Corporate and personal income tax rates do not depend on citizenship; tax residency is a separate test.
Example: Mei, a hypothetical PR of six years, owns 80% of a Singapore trading company and is its only resident director. She applies for citizenship. Her company’s shareholding, bank mandates and ACRA records do not change on the grant, but she updates her identity details with ACRA and the bank once her new NRIC is issued, notes the new status in payroll, and delays a planned flat purchase until after the grant to fall under citizen ABSD rates. Her 15-year-old son was already liable for NS as a PR, so the family’s NS position does not change.
Should you apply now? Questions to settle first
- Are you prepared to give up your current citizenship, including any property, inheritance or residence rights tied to it in your home country?
- Do your sons’ NS obligations fit the family’s education and career plans?
- Will the company’s records, your tax filings and your employment letter tell a consistent story?
- Do your will, CPF nominations and estate plans need updating? Our succession planning guide across PR and citizenship covers this.
- If you are not yet a PR, start with our Singapore PR application guide.
Frequently asked questions
Can I keep my foreign passport after becoming a Singapore citizen?
Not as an adult. Applicants aged 21 and above must renounce their foreign citizenship before taking the oath, and may need to submit proof of final renunciation within 15 months of the grant.
Should I renounce my current citizenship before applying?
No. ICA tells applicants not to renounce until they have downloaded the Final Outcome Letter. Renouncing earlier could leave you without citizenship if the application does not succeed.
Can I appeal if my application is rejected?
ICA accepts an appeal through its e-Service only if the application was rejected within the last 12 months, and invites you to upload new supporting documents. There is no appeal fee.
Does becoming a citizen change my company’s filings?
Not the filings themselves. Your identification details change, so update ACRA, banks and service providers once your NRIC is issued. Our guide to the company compliance calendar sets out the filings that continue as before.
Can my spouse and children apply with me?
Family members can be included or apply under their own eligible routes. Each person is assessed, and each child’s NS and dual citizenship position should be checked separately.
