◉No visa needed — but the arrival card is not optional
Indonesian ordinary passports enter Singapore visa-free for tourism up to 30 days (ASEAN arrangement). There is nothing to apply for and nothing to pay. What is required is the SG Arrival Card, and it is free.
- Submit the SGAC on the ICA e-Service within 3 days of arrival — for a 28 March landing, any time from 25 March. It includes the health declaration.
- It is per person and per entry. Fill in the hotel address and flight number; save the confirmation email offline.
- Only the official ICA site is free. The first search results are often paid lookalikes that file the same form for S$20–40.
- Passport valid at least 6 months, and a return or onward ticket — airlines ask for it at check-in, immigration can ask at the counter.
