Once this requirement is fulfilled, you may proceed to submit your marriage application on the 'Our Marriage Journey' website (Civil Marriage). These 31 days, which do not include the day of arrival in Singapore, can be fulfilled in a single visit made to Singapore at any time before the marriage application is submitted.
If you or your spouse-to-be is not a Singapore Citizen or Permanent Resident and you intend to be married in Singapore, the law requires at least one of you to be present in Singapore for a minimum of 31 continuous days.
