What this bill does

In plain words · AI-written from the official summary

Shadow Wolves employment and expansion upgrades

This bill makes changes to how the Shadow Wolves, a U.S. border patrol unit operating on Tohono O'odham Nation lands in Arizona, handles employment and growth. It allows certain agents in the program to move into a different type of federal job classification that requires passing exams and following standard hiring rules. The bill also requires the agency to work with tribal partners to clarify the program's goals, plan for expansion, figure out what skills and staffing it needs, and develop a plan for when agents retire.

How it affects you

This primarily affects agents currently working in the Shadow Wolves program and potentially people who may join it in the future. For existing officers in the unit, the bill requires the agency to give them information about switching to the special agent job classification. Tribal nations that partner with the program, especially the Tohono O'odham Nation, are involved in the decision-making about the program's mission and where it might expand to other tribal lands.

Shadow Wolves Improvement Act

This bill allows for the revision of the federal employment classification of the Shadow Wolves, a tactical patrol unit in Homeland Security Investigations currently operating on the lands of the Tohono O'odham Nation in Arizona on the U.S.-Mexico border, and establishes other requirements related to the expansion of the Shadow Wolves program.

Specifically, the bill allows U.S. Immigration and Customs Enforcement (ICE) to noncompetitively convert certain special agents serving in the Shadow Wolves program from the excepted service to the competitive service. Competitive service positions in the federal government are subject to examinations and a statutorily defined hiring process. These agents must have served in the unit for three years to qualify for the conversion regardless of the location assigned.

In coordination with appropriate representatives of partnering tribal governments, including the Tohono O'odham Nation, ICE must (1) specify the mission and goals of the Shadow Wolves program, and (2) update the strategy for the expansion of the program.

Additionally, ICE must (1) determine national staffing needs and required skills for the program, (2) provide current Shadow Wolves classified as officers written information about reclassifying as special agents, (3) develop a succession plan for anticipated retirements among agents in the program, and (4) develop criteria for evaluating and selecting additional tribal lands on which additional Shadow Wolves units may be located.

ICE must report to specified congressional committees regarding the implementation of this bill.
