The General Accounting Office investigation focused on four FPF offices: Laredo, Texas; Los Angeles; New York; and Seattle. Processing backlogs, inadequate internal controls, and personnel turnover at FPF offices have been highlighted in several Customs and GAO reports over the past 10 years. While observations of the four FPF offices in 1987 indicated that these problems still exist, the report emphasizes that Customs has taken several corrective actions. In addition to creating the headquarters office in 1986, Customs has automated case processing and provided additional training for FPF officers. Other planned improvements include standardizing case processing, improving internal controls, and addressing personnel issues such as position grades and career ladders. According to the report, Customs' success depends on its ability to complete and implement these initiatives in a timely manner.
