Application procedure

All Singapore citizenship applications must be submitted online using the e-Service.

You will need a SingPass account to submit your application. If you are applying under the sponsorship of your spouse/ Singapore Citizen parent, your sponsor would need to log in via his/her SingPass account.

The application procedure consists of four main steps:

Step 1

Online application – submit your application and supporting documents online.

  • Prepare all the required documents before initiating the application procedure
  • During the online application, you will be provided with a questionnaire which you will need to accurately fill in together with all forms which will be automatically generated based on your responses in the questionnaire
  • Once the online application has been initiated you will be given 7 days to fill in the data for the sponsor and all applicants. Each individual application should take you about 90 minutes to complete
  • Double check the accuracy of your information
  • Complete your declaration and consent for the authorities to access your personal data and make the payment

Step 2

Approval in principal. Download the in-principal approval letter to complete your Singapore Citizenship Journey and participate in the mandatory sessions described below. This stage takes approximately two months.

  • You will need to book a slot and participate in the Singapore Experiential Tour and Community Sharing Session
  • Complete the online e-Journey session
  • Inform yourself of the stages you will need to undertake in order to renounce your current citizenship when it is time to do so during the next stage of the process

Step 3

Final approval and renunciation of your citizenship. You will receive a letter to renounce foreign citizenship. This stage takes approximately 1 to 2 months.

  • You will need to fulfil the requirements for renunciation of your foreign citizenship described in the letter which you will receive (e.g. settle property ownership or others)
  • Follow the application procedure to renounce your foreign citizenship at the relevant embassy
  • Prepare all documents required for the citizenship registration
  • Go to the ICA Building on the date and time indicated on your letter

Step 4

Citizenship ceremony. The ceremony usually takes place 3 to 6 months after the successful completion of Step 3. Following the ceremony, you will be given a Pink Identity Card (also known as NRIC) and SC Certificate.

Overall, the procedure takes somewhere from 6 to 12 months to be completed.
