Singapore Bolsters Immigration Protocols With New No-Boarding Directive System To Prevent Security Risks At Changi And Seletar Airports

Published on December 22, 2025

Singapore is ramping up its border security with the introduction of a new No-Boarding Directive (NBD) system set to take effect from January 30, 2026. This measure will require airlines to prevent high-risk or undesirable travelers from boarding flights to Singapore, using a proactive approach to stop potential security threats before they reach the country. By issuing NBD notices to airlines at Changi and Seletar Airports, Singapore aims to enhance its immigration controls and ensure the safety of its borders.

To address increasing security concerns, Singapore is tightening its border entry requirements with the introduction of multiple layers of enhanced security.Starting January 30, 2026, the Immigration & Checkpoints Authority (ICA) will introduce a stringent security measure, compelling airlines at Changi and Seletar Airports to enforce No-Boarding Directives (NBD) for travelers identified as high-risk.for high-risk travelers.These notices will prevent individuals who are either undesirable or prohibited from boarding flights destined for Singapore, ensuring they do not enter the country in the first place. This new proactive measure is aimed at strengthening the country’s border security.

Use of Advance Traveler Information

Currently, ICA uses advanced traveler information, including data from the SG Arrival Card (SGAC), flight manifests, and other sources, to identify high-risk travelers before they arrive at Singapore’s checkpoints. Upon arrival, ICA flags these travelers for additional scrutiny when they clear immigration. However, from January 2026, the ICA will step up its efforts by issuing NBD notices to airlines, which will prevent prohibited or undesirable individuals from boarding their flights. Airlines that receive these notices will be required to stop these travelers from boarding. The NBD system will also apply to travelers who fail to meet entry criteria, such as not possessing a valid visa or lacking travel documents with at least six months of validity.

NBD’s Role in Strengthening Security

The implementation of NBD notices directly enhances Singapore’s security by preventing high-risk travelers from even attempting to board flights. The goal is to stop potential threats before they reach Singapore, reducing the burden on the country’s immigration system and protecting national security. ICA has briefed airline operators and is working closely with them to ensure the smooth rollout of the NBD system. When airlines receive traveler data, ICA will scrutinize passengers heading to Singapore. If any traveler does not meet the entry requirements or poses a security risk, ICA will issue an NBD notice, stopping that individual from boarding the flight.

When a traveler who is subject to an NBD arrives at the airport to check in for a flight to Singapore, the airline must refuse to allow them on board. In certain instances, airlines may need to carry out additional checks, such as verifying the validity of a visa or ensuring the submission of an SGAC, before granting permission to board.

Appeal Process for Denied Travelers

If a traveler is denied boarding due to an NBD notice but still intends to travel to Singapore, they can request approval for entry. The traveler must contact ICA through the Feedback Channel, seek approval, and then make arrangements for a new flight. This process ensures that individuals who have been denied entry can still appeal their case, as long as they meet the required conditions for entry.

Consequences for Non-Compliance

Airline operators must comply with NBD notices, or they will face strict penalties under Singapore’s Immigration Act. If an airline disregards an NBD notice and allows a traveler to board, the airline could face a fine of up to S$10,000 (about US$7,740). If the airline’s pilot or any other employee assists in allowing a person subject to an NBD to board the flight, they could face individual penalties, including a fine A fine of as much as S$10,000 or a prison sentence of up to six months.In severe cases, both a fine and imprisonment may apply. These penalties emphasize the importance of adhering to Singapore’s entry regulations.

Increase in Denied Entries

According to reports, around 41,800 foreigners were turned away at Singapore’s checkpoints in the first 11 months of 2025. This represents a 26% increase compared to 2024 and a 46% rise over the number of individuals denied entry in 2023. The growing number of denied entries highlights the effectiveness of the current border security measures and the need for more stringent protocols like the NBD system. As a result, this new initiative will further strengthen Singapore’s ability to manage immigration risks and ensure that only eligible travelers are allowed to enter the country.

To enhance border security, Singapore will implement a new No-Boarding Directive (NBD) system starting January 30, 2026, requiring airlines to block high-risk travelers from boarding flights bound for the country.

By implementing these enhanced security measures, Singapore is taking a more proactive role in safeguarding its borders. The NBD system, effective from January 2026, aims to identify potential threats early, preventing individuals who pose security risks from entering the country. These measures align with global trends in enhancing border security and streamlining the entry process for legitimate travelers. As the number of denied entries continues to rise, Singapore’s focus on tightening border controls reflects the nation’s commitment to maintaining a safe and secure environment for its citizens and visitors alike.
