Singapore will tighten travel checks from January 30 next year. The Immigration & Checkpoints Authority (ICA) announced a new “no-boarding directive” that allows airlines to stop certain passengers before they even depart for Singapore.

Under the new rule, travellers who do not meet entry requirements or who are flagged as “undesirable” may be denied boarding at their departure airport.

Airlines Must Check Passenger Details Before Boarding

The directive requires airlines to verify advance passenger information before allowing anyone to board a flight to Singapore. These checks include visa status, passport validity, SG Arrival Card details, and any past immigration or security alerts.

If a passenger fails these checks, the airline must deny boarding. The traveller will not be allowed to fly to Singapore in the first place.

Heavy Penalties for Airlines and Staff

The ICA warned airlines to follow the directive strictly. Airlines that allow flagged passengers to board can face fines of up to SGD 10,000.

Airline staff, including pilots and ground personnel, may also face penalties. If found complicit, they can be fined up to SGD 10,000, jailed for up to six months, or face both punishments.

Appeals Still Possible for Affected Travellers

Travellers who are denied boarding are not completely barred from travel. They can appeal the decision by contacting ICA through the “ICA Feedback Channel.”

If ICA grants approval, the traveller may rebook the flight and travel later.

Checks Move From Arrival to Departure

The new measure shifts Singapore’s immigration and security checks to an earlier stage. Instead of screening risky travellers only on arrival, authorities will now stop them before they fly.

ICA advised business travellers, tourists, HR teams, travel agents, and frequent flyers to double-check all documents before booking or checking in. Under the new system, even minor issues could lead to boarding refusal.

How Advance Traveller Information Is Used

At present, ICA already uses advance traveller information to assess risks. This data comes from SG Arrival Cards, flight manifests, and other sources. High-risk travellers usually face extra screening when they arrive in Singapore.

From January 2026, ICA will go further. It will issue Non-Boarding Directive (NBD) notices directly to airlines.

What the Non-Boarding Directive Covers

An NBD instructs airlines to stop specific passengers from boarding flights to Singapore. The rule targets travellers who pose security risks or fail to meet entry conditions.

These conditions include holding a valid visa and carrying a travel document with at least six months of remaining validity.

Purpose of the New Directive

ICA said the NBD strengthens border security by preventing risky travellers from reaching Singapore at all. The goal is to block threats before they arrive at the country’s checkpoints.

“Airline operators which fail to comply with an NBD notice will be guilty of a strict liability offence under the Immigration Act 1959 and may face fines of up to SGD 10,000. Pilots or airline employees who allow a person subject to an NBD to board — whether by act or omission — may be fined up to SGD 10,000, jailed for up to six months, or both,” ICA said.

What Travellers Should Do Now

Travellers planning to fly to Singapore should ensure all documents are valid and complete well in advance. Airlines will now deny boarding if any issue appears during checks.

The new rule makes compliance essential, not optional.
