U.S. Customs and Border Protection (CBP) is responsible for keeping terrorists and other dangerous people from entering the country while also facilitating the cross-border movement of millions of travelers. CBP carries out this responsibility at 326 air, sea, and land ports of entry. In response to a congressional request, GAO examined CBP traveler inspection efforts, the progress made and the challenges that remain in staffing and training at ports of entry, and the progress CBP has made in developing strategic plans and performance measures for its traveler inspection program. This is a public version of a For Official Use Only report GAO issued on October 5, 2007. To conduct its work, GAO reviewed and analyzed CBP data and documents related to inspections, staffing, and training, interviewed managers and officers, observed inspections at eight major air and land ports of entry, and tested inspection controls at eight small land ports of entry. Information the Department of Homeland Security (DHS) deemed sensitive has been redacted.
CBP has had some success in identifying inadmissible aliens and other violators, but weaknesses in its operations increase the potential that terrorists and inadmissible travelers could enter the country. In fiscal year 2006, CBP turned away over 200,000 inadmissible aliens and interdicted other violators. Although CBP's goal is to interdict all violators, CBP estimated that several thousand inadmissible aliens and other violators entered the country though ports of entry in fiscal year 2006. Weaknesses in 2006 inspection procedures, such as not verifying the nationality and admissibility of each traveler, contribute to failed inspections. Although CBP took actions to address these weaknesses, subsequent follow up work conducted by GAO months after CBP's actions found that weaknesses such as those described above still existed. In July 2007, CBP issued detailed procedures for conducting inspections including requiring field office managers to assess compliance with these procedures. However, CBP has not established an internal control to ensure field office managers share their assessments with CBP headquarters to help ensure that the new procedures are consistently implemented across all ports of entry and reduce the risk of failed traveler inspections. CBP developed a staffing model that estimates it needs up to several thousand more staff. Field office managers said that staffing shortages affected their ability to carry out anti-terrorism programs and created other vulnerabilities in the inspections process. CBP recognizes that officer attrition has impaired its ability to attain budgeted staffing levels and is in the process of developing a strategy to help curb attrition. CBP has made progress in developing training programs, yet it does not measure the extent to which it provides training to all who need it and whether new officers demonstrate proficiency in required skills. CPB issued a strategic plan for operations at its ports of entry and has collected performance data that can be used to measure its progress in achieving its strategic goals. However, current performance measures do not gauge CBP effectiveness in apprehending inadmissible aliens and other violators, a key strategic goal.
