A CBP security clearance is issued by the U.S. Customs and Border Protection agency, which is part of Homeland Security. Security clearances authorize access to certain information for personnel of this branch.
The CBP's main mission is protecting the U.S. by keeping weapons and terrorists out of the country. A security clearance is vital in following this objective. Security clearances allow only authorized individuals access to sensitive national security information. Security clearances require a long investigation of the individual which must result in a determination that the individual is 100 percent trustworthy.
The CBP strives to keep terrorists and weapons out of the U.S. While doing this, the CBP is also responsible for other protection activities, such as enforcing drug laws and stopping illegal immigration.
Only authorized employees of the CBP can access sensitive information. To obtain security clearance, these employees undergo an in-depth background check. Security clearances are granted by the Office of Personnel Management, or OPM. Applicants must complete a 17 page questionnaire which is investigated and examined by the OPM.
