Who needs to fill in a D/E card?
Every visitor is required to produce a completed D/E card for immigration clearance whenever they visit Singapore.
You must use neat and legible handwriting when you fill in your card, and use either blue or black ink.
Present your completed D/E card and travel documents to the ICA officer at the immigration counter. The officer will keep the disembarkation portion of the card and return the embarkation portion to you.
When you leave Singapore, hand the embarkation portion to the ICA officer. If you have lost it, inform an ICA officer at your point of departure.
