An international border is the official dividing line between two countries. It marks where the territory, laws, and authority of one country end and another’s begin.

  • Border checkpoints - Places where people and goods are inspected (e.g. airports, land crossings).
  • Passports and visas - Usually required to cross legally.
  • Security or fencing - Some borders have fences, walls, or patrols for control.
  • Customs and immigration - Control who and what enters or leaves the country.
