The introduction of this Act provides its short titles, the "Clear Law Enforcement for Criminal Alien Removal Act of 2025" or "CLEAR Act of 2025," and lists the sections of the Act, which cover topics including the role of states in immigration law enforcement, information sharing with federal entities, financial assistance for law enforcement, and related procedures and authorizations.

The section defines terms used in the Act, specifying that "Secretary" refers to the Secretary of Homeland Security, and "State" is defined according to a specific section of the Immigration and Nationality Act.

State and local law enforcement officers have the power to help enforce U.S. immigration laws by identifying, arresting, and transferring immigrants to federal custody. This authority is confirmed as natural to states and has not been overridden by Congress.

This section encourages States to allow their law enforcement officers to help enforce federal immigration laws, as those that don't won't receive certain federal funds. It also clarifies that law enforcement officers are not required to report or arrest crime victims or witnesses, and any funding removed from non-complying States will be redirected to those that comply.

The section mandates that the Commissioner for U.S. Customs and Border Protection must regularly give the National Crime Information Center (NCIC) details about certain immigration violators, such as those with removal orders or expired visas. The NCIC will add this data to their Immigration Violators File, even if the person hasn't been notified, has already been deported, or if there's limited identification available. Moreover, the law requires modifications to the U.S. Code to ensure that records of immigration violations are collected and preserved, with these changes being enforced within six months.

State and local law enforcement agencies are required to share information with the Secretary of Homeland Security about apprehended individuals suspected of violating U.S. immigration laws. This includes details like the person's name, address, physical description, and, if available, additional identification. The Secretary must report annually to Congress on compliance and reimburse law enforcement for related expenses but does not require sharing information about crime victims or witnesses.

The section outlines that the Secretary can give grants to state and local law enforcement for equipment and facilities to help enforce immigration laws. To be eligible, these agencies must assist in immigration enforcement and not have policies stopping officers from checking a person's immigration status. It also mandates an audit of the funds used, three years after the law's enactment.

The section mandates the Secretary to build or acquire 20 new detention facilities in the U.S. for housing aliens awaiting removal. It also updates a legal provision to specify that funding for these facilities comes from U.S. Immigration and Customs Enforcement's budget.

The section outlines the procedures for transferring custody of undocumented immigrants from state or local law enforcement to federal authorities. It specifies timely detention requirements, reimbursement to states for associated costs, and the provision of secure facilities to ensure appropriate handling throughout the process.

The text outlines the handling of aliens unlawfully present in the U.S. It defines the term "alien unlawfully present," describes the process for state and local officials to request federal custody of such persons, and mandates prompt federal incarceration or detention while providing guidelines for facilities and reimbursement for states.

The section outlines the development of a training manual and pocket guide for State and local law enforcement on immigration law enforcement, which will be created by the Secretary within six months. It specifies that training will be accessible through various methods, such as residential, onsite, online, or DVD, and an e-learning system will be implemented within 120 days, all at no cost to State and local officers, and it does not obligate them to carry the training materials while on duty.

Law enforcement officers and agencies in a state or local area are protected from being personally sued while doing their job, just like federal officers. However, an agency can still be sued if one of its officers breaks the law while enforcing immigration laws.

The Institutional Removal Program is designed to identify, detain, and remove criminal aliens from the U.S. after they complete their prison sentences. The program will be expanded to every state, and each state that gets federal money for holding criminal aliens must work with the program. Local officers can detain these aliens for up to 14 days after they finish their state prison sentence so federal agents can take custody. Additionally, technology like video conferencing and mobile access to federal databases will be used to support remote locations.

The text authorizes the U.S. Department of Homeland Security to receive whatever funds are necessary from the government for the year 2025 and every year after to implement this Act. It also updates a section of the Immigration and Nationality Act to allow necessary funding for a specific program each year starting in 2025.

If any part of this law or its amendments is found to be invalid, the rest of the law and its amendments will still remain in effect and apply to those not affected by the invalidity.
