A quick guide for anyone flying to Singapore. The SG Arrival Card is the free electronic arrival and health declaration most foreign visitors must submit before entering Singapore — it is not a visa, and it costs nothing through ICA's official channels. Timing matters most: submit within 3 days before arrival, with arrival day counting as one of those days. Full guide: SG Arrival Card (https://sgarrivalcardinfo.com/) — and read this guide to the SG arrival card 3-day rule (https://sgarrivalcardinfo.com/sg-arrival-card-3-day-rule/) before you submit. If your confirmation email has not arrived, see this guide on the SG arrival card confirmation email not received (https://sgarrivalcardinfo.com/sg-arrival-card-confirmation-email-not-received/). Independent guide — not an official government website.
