Border patrol refers to the government agency responsible for monitoring and securing a country's borders. Their main duties include preventing illegal immigration, smuggling, and trafficking. Agents work in various locations, including land borders, airports, and coastal areas, using technology and physical barriers to help maintain security. In the United States, the U.S. Customs and Border Protection (CBP) oversees border patrol operations. Agents are trained to detect and apprehend individuals attempting to cross borders unlawfully. They also facilitate legal crossings and ensure that customs regulations are followed, balancing security with the movement of people and goods.
