International passenger facilitation: mandatory customs training and help desk requirement to improve airport passenger assistance for arrivals and departures. Chief Commissioners must ensure newly posted Customs officers at international airports undergo mandatory training on rules and passenger handling, repeated at regular intervals and coordinated with NACEN and other agencies. Customs must establish a prominent Help Desk after immigration in arrival halls and in departure halls, with signboards, appropriately selected officers, and necessary forms and information to guide international passengers.
