Hurt a federal K-9, lose your right to stay in America

Why it matters

Harming a federal police dog or horse — an offense that starts at up to one year in prison — would become grounds for deportation. H.R. 4638 passed the House 228-190 and would let a conviction — or just an admission — block a non-citizen's entry or end their stay in the U.S.

The Federal Working Animal Protection Act is two sentences long. It takes an existing federal crime — willfully and maliciously harming a police animal — and writes it into immigration law as its own ground for keeping someone out and for sending someone home.

That underlying crime is narrower than it sounds. Federal law defines a police animal as a dog or horse employed by a federal agency to detect crime, enforce laws, or catch offenders. A local sheriff's K-9 is generally covered by state law instead, not by this federal offense.

A criminal conviction is not required: admitting the offense, or admitting the acts that make it up, would be enough to make a non-citizen inadmissible or deportable. That admission language mirrors how immigration law already treats drug offenses and crimes involving moral turpitude.

The bill applies at both doors. Someone applying for a visa or arriving at the border could be found inadmissible, and someone already living here — including a lawful permanent resident — could be found deportable, based on the same conduct.

Under current law, the federal offense carries up to 1 year in prison, or up to 10 years if the animal is permanently disabled, disfigured, seriously injured, or killed. The bill attaches removal to the entire range, including the lower-level version. It creates no new crime and no new spending.

H.R. 4638 Bill Summary

What H.R. 4638 actually does.

1

Harming a federal police animal can bar you at the border

A non-citizen convicted of the federal offense of harming a police animal — or who admits the offense or the acts behind it — would be inadmissible, meaning they could be denied a visa or entry to the U.S.

2

Green card holders and other residents could face removal

The same three triggers would make a non-citizen already in the U.S. deportable. That includes lawful permanent residents, not only people here on temporary visas or without status.

3

An admission can count as much as a conviction

Immigration consequences could follow from a person's own admission to the offense, or to the acts that make up its essential elements, even if no criminal court ever found them guilty.

4

Covers federal agency dogs and horses only

The bill ties into an existing federal law that protects dogs and horses employed by federal agencies — such as detection dogs and mounted units — for law enforcement work. It does not reach general animal cruelty.

5

Lower-level offenses count too

The federal offense carries up to 1 year in prison for basic harm and up to 10 years when the animal is seriously injured, disabled, disfigured, or killed. The bill makes no distinction between the two tiers.

6

No new crime and no new money

H.R. 4638 does not create a criminal offense or fund any program. Its only effect is on immigration status.

Who benefits from H.R. 4638?

Federal K-9 and mounted units

Detection dogs and horses working for agencies like Customs and Border Protection, the Secret Service, and federal police forces would gain an additional deterrent: harming them could cost a non-citizen their immigration status.

Federal animal handlers

The officers who train, live with, and deploy these animals would see a tougher consequence attached to attacks on their partners.

Immigration enforcement officials

Officers and government attorneys would get an explicit, standalone ground to deny admission or seek removal, rather than arguing whether the conduct fits a broader category such as a crime involving moral turpitude.

Who is affected by H.R. 4638?

Lawful permanent residents and visa holders

Non-citizens living in the U.S. legally could be placed in removal proceedings over a single covered offense, including one at the lower sentencing tier.

Visa applicants and travelers at ports of entry

Consular officers and border officials would screen for the new ground. Past conduct involving a federal police animal could lead to a visa denial or refusal at the border.

Non-citizens who make statements to officials

Because an admission can trigger the bill, what a person says in a visa interview, at the border, or in immigration proceedings could carry the same weight as a conviction.

Criminal defense and immigration attorneys

Lawyers negotiating plea deals in federal police-animal cases would need to weigh removal risk for non-citizen clients, since even a misdemeanor-level plea would count.

Immigration judges and adjudicators

Judges and officers would have to decide whether a record or statement shows each essential element of the federal offense, including that the harm was willful and malicious.

H.R. 4638 Common Questions

What does H.R. 4638 do?

It makes harming a federal police animal a standalone ground for denying a non-citizen entry to the U.S. or deporting them. It builds on an existing federal crime rather than creating a new one.

Can hurting a police dog get you deported?

Under H.R. 4638, yes — if the dog works for a federal agency and the harm was willful and malicious. The bill applies to any non-citizen, including green card holders.

Does H.R. 4638 cover local police dogs?

Generally no. The federal law it relies on covers dogs and horses employed by federal agencies, such as Border Patrol detection dogs. Harm to a city or county K-9 is usually handled under state law.

Do you need a conviction for H.R. 4638 to apply?

No. Admitting the offense, or admitting the acts that make it up, would also count. Immigration law already uses the same admission language for drug offenses and crimes involving moral turpitude.

What is the penalty for harming a federal police animal?

Up to 1 year in prison and a fine, or up to 10 years if the animal is seriously injured, permanently disabled, disfigured, or killed. H.R. 4638 adds possible deportation on top of either tier.

Could a green card holder lose their status under H.R. 4638?

Yes. Lawful permanent residents are non-citizens, so a covered conviction or admission could make them deportable, not only people on temporary visas.

Did H.R. 4638 pass the House?

Yes. The House passed it 228-190 on March 19, 2026. It was received in the Senate the same day and referred to the Judiciary Committee.

Who sponsored H.R. 4638?

Rep. Ken Calvert (R-CA) introduced it on July 23, 2025, as the Federal Working Animal Protection Act. It has 19 cosponsors, all Republicans.
