Singapore's Immigration & Checkpoints Authority (ICA) is set to begin issuing No-Boarding Directive (NBD) notices to airlines at Changi and Seletar airports starting January 30, 2026. This policy aims to prevent the entry of undesirable or prohibited individuals and travelers who do not meet entry requirements. The directive is part of Singapore's efforts to bolster border security and ensure compliance with immigration laws, impacting multiple airlines operating in the region. According to Chen Chuanren, Southeast Asia and China Editor for the Aviation Week Network, these measures align with Singapore's strategy to maintain its status as a key international aviation hub and enhance immigration controls. The initiative reflects ongoing efforts to improve the safety and security of air travel in Singapore.
