U.S. Customs and Border Protection (“CBP”) officers have been instructed not to refer to the Inspector’s Field Manual (“IFM”). The IFM was a 350+ pages comprehensive “how to” manual that detailed official CBP policies and procedures in an effort to carry out the mission of CBP. The IFM was used in conjunction with the Immigration and Nationality Act (INA), Title 8 of the Code of Federal Regulations (8 CFR), and other official CBP directives. Officers have been given access to a new, electronic instruction manual that is currently under development and which has not been made publicly available. While officers at individual Ports of Entry may still refer to the manual, it is no longer an official manual of the agency. Practitioners, users and passengers should no longer refer to the IFM as a procedural or interpretive authority.
