U.S. Customs and Border Protection (CBP), an agency within the U.S. Department of Homeland Security, controls the flow of goods and people into the United States to prevent terrorists, high-risk and improperly documented travelers and goods from entering the United States, while facilitating the entry of legitimate travelers and trade into the United States. CBP’s work focuses at the borders of the United States, including airports, land borders and seaports.
As an international student, you will interact with CBP officers at the port of entry when entering and exiting the United States. At the port of entry, officials will determine whether you can enter the United States, based on the inspection and examination they conduct upon arrival.
