The acronym "POM" stands for "Principal Officer in Charge of Movement." This term is used by customs and border control agencies to refer to an individual who has been designated as responsible for managing the movement of people or goods across a particular border. The POM acts as a liaison between the arriving travelers, shippers, or cargo owners and the relevant authorities in charge of clearance procedures. They are tasked with ensuring that all necessary documentation is presented, and that any required inspections or examinations take place before entry into the country is granted. In summary, a POM serves as the primary point of contact for managing the flow of people and goods across international borders.
