California state law. County rules for San Mateo and Santa Clara counties. Federal immigration law applies everywhere. If you are on probation in another state, these California limits do not apply; ask a local public defender what your state's rules are.

This is general information, not legal advice. For your own case, talk with your defense lawyer and an immigration attorney or DOJ accredited representative.

Will my probation officer tell ICE about me?

In California, probation is not supposed to be a pipeline to ICE. State law limits how local agencies help with immigration enforcement. In San Mateo County, a county law goes further and covers every county department.

But "limited" doesn't mean "never." Some information can still reach immigration agents, and federal law protects certain sharing. Knowing the difference helps you stay safe and keep your focus on finishing probation.

We know this worry can sit on you at every check in. You are doing the right thing by showing up.

What can probation share with ICE?

The California Values Act sets limits for state and local law enforcement agencies, and county probation departments are covered. The law defines a local law enforcement agency to include any agency that monitors compliance with probation or parole conditions (Gov. Code 7284.4, using the definition in Gov. Code 7283). The state Attorney General's January 2025 guidance says these agencies may not:

  • Ask about your immigration status
  • Give ICE your personal information, like your home or work address, unless that information is already public
  • Give ICE your release date, except in certain cases (see below)
  • Hold you past your release time because ICE asked
  • Arrest you for a civil immigration violation
  • Give ICE office space set aside only for them in county law enforcement buildings

What can still happen:

  • Your criminal history can be shared if immigration agents ask, when local policy allows it.
  • Your citizenship or immigration status, if an agency has it on file, can be shared. Federal law protects that exchange.
  • A judicial warrant signed by a judge can change what an agency may do.
  • Certain serious convictions open more doors. If you were convicted of a serious or violent felony, or certain other listed felonies, an agency may choose to tell ICE your release date or transfer you. Agencies never have to. A plain misdemeanor is never a reason.
  • An ICE interview while you are in custody can happen only after you get a written consent form. The interview is voluntary. You can say no, or ask to have only your lawyer there.

Some probation departments, like San Luis Obispo County's, also write these limits into their own policy.

What are the rules in my county?

San Mateo County. In April 2023, county supervisors voted to stop county departments and staff from using county money, time or property to help immigration enforcement, and from sharing personal information with immigration agents. There are exceptions for a federal judge's warrant, a court order or a statute, and for criminal cases not about immigration. In November 2025, the county strengthened that law. The Probation Department now publishes how many immigration requests it gets:

  • Immigration detainer requests: 0 in every month from January 2025 through August 2026
  • Immigration inquiries: 1 in January 2026 and 1 in May 2026

See the county's Probation immigration data page.

Santa Clara County. The county's civil detainer policy says it will not hold anyone past their release date for ICE unless ICE brings a judicial warrant. The Board voted to keep that policy in 2019. We did not find a separate written policy from Santa Clara County Probation on ICE requests (searched October 21, 2026). The state Values Act limits above still apply to it. If you want to know more, ask the Public Defender's office.

Other California counties. The state limits apply to every county probation department. Your county may have its own, stronger policy. Ask your defense lawyer or search your county's website for "immigration" and "probation."

What can I do at my check ins?

  • Go to every appointment, on time. Follow every term. This is the best protection you have.
  • You don't have to bring up your immigration status. Probation should not ask. If someone asks where you were born or what your status is, you can say you would like to talk to your lawyer first.
  • Never show false papers or say you are a U.S. citizen. A false claim to citizenship can bar a green card for good (8 USC 1182).
  • Keep your papers together: your court order, your probation terms and your lawyer's number.
  • Have a family plan in case something goes wrong. See Make a family preparedness plan and If immigration agents come.

Can I end probation early?

Yes, you can ask. Under California Penal Code 1203.3, the court can change or end probation early (sample court petition, Madera County Superior Court). Each county court has its own form. Your lawyer files a request with the court that sentenced you, and the judge decides. Courts look at things like paying restitution and following your terms.

Also check how long your probation should be. A California law that took effect in 2021 (AB 1950) cut most misdemeanor probation to 1 year and most felony probation to 2 years. Some crimes are excluded (Tuolumne County Superior Court). If your term looks too long, ask your defense lawyer.

Ending probation early does not erase a conviction for immigration purposes. To learn what can, see Does clearing my record in California help my immigration case? and Ways to fix an old California conviction.

Why does finishing probation matter?

If you have a green card and want to become a citizen, USCIS will not approve your application until your probation is finished (8 CFR 316.10(c)(1)). Completing probation is also something USCIS can count in your favor when it looks at good moral character (USCIS policy memo PM-602-0188, AILA copy). See Applying for citizenship with an arrest or record.

Questions people ask

If I violate probation and go back to jail, will ICE get me? A county jail is covered by the same Values Act limits. It may not hold you past your release time for ICE. It may tell ICE your release date or transfer you only if you have certain serious or violent felony convictions, and it never has to. See Will ICE pick me up when I leave a California jail or prison?

Can probation stop ICE from arresting me? No. The Values Act limits what local agencies do. It does not control federal agents. That is why a family plan and a lawyer's number matter.

Should I tell my probation officer my status if I am asked? You don't have to volunteer it. Do not lie. You can say you want to talk with your lawyer first. This wording is with an attorney for review.

Will ending probation early help my immigration case? It can help with citizenship timing and shows good conduct, but it does not erase the conviction. Ask an immigration attorney before you file anything in criminal court.

Is there a checklist I can print?

Yes. Keep it with your probation papers.
