After you have completed the SC Journey, ICA will send the approval letter notification to you when it is ready. We are unable to estimate how long this would take. Please note that if you have applied for Singapore citizenship as part of a family unit application, the approval letters of all applying members will only be sent after every member has completed the SC Journey.
Please do not renounce your foreign citizenship or surrender your foreign passport until you have received the approval letter from ICA. The letter will detail the next steps that you should take.
You may contact ICA at ICA_Citizenship_Unit@ica.gov.sg or 6391 6100 if you wish to find out more about the approval letter, citizenship registration (stage 3) or citizenship ceremony (stage 4).
