CBP officer’s border

Instructions: Read the text to do the activities suggested.

A U.S. Customs and Border Protection (CBP) officer's border search authority is derived from federal statutes and regulations.

Since it was created, it has not been the intent of CBP to subject travelers to unwarranted scrutiny. CBP inspection procedures are designed to facilitate the entry of U.S. citizens and aliens who can readily establish their admissibility. CBP officers must determine the nationality of each applicant for admission and, if determined to be an alien, whether or not the applicant meets the requirements of the Immigration and Nationality Act for admission to the United States. CBP officers may, unfortunately, affect law-abiding citizens in order to detect those involved in illicit activities. They are especially aware of how inconvenient and stressful the inspection process may be to those selected for inspection.

For years, speaking with travelers and closely examining their documentation have been some of the ways they have looked for mala fide or improperly documented travelers. However, CBP officers are expected to conduct their duties in a professional manner and to treat each traveler with dignity and respect.
