In police terms, RA usually stands for one of two things: Rescue Ambulance, the shorthand officers and dispatchers use on the radio to call for emergency medical response, or Resident Alien, the immigration classification noted on booking sheets and reports for someone who holds lawful permanent resident status. A handful of smaller departmental uses exist, but these two cover almost every situation the public actually runs into.
Rescue Ambulance on the Radio
Over a police scanner or in dispatch logs, “RA” almost always means Rescue Ambulance. An officer at a scene might radio “send an RA to the location” to request paramedics for a victim, a suspect, a bystander, or someone already in custody. Several large departments, especially in Southern California, have used the term in their standard radio protocol for decades.
It’s departmental jargon, not a legal term. You won’t find it in statutes or court records. When you see “RA” followed by a unit number in a dispatch log, that’s an ambulance crew responding to a medical call.
Resident Alien on Booking Paperwork
In booking records, reports, and anything touching immigration, “RA” means Resident Alien. A resident alien is a non-citizen with lawful permanent resident status, usually documented by a Permanent Resident Card, officially Form I-551 and commonly called a Green Card.1U.S. Citizenship and Immigration Services. 13.1 List A Documents That Establish Identity and Employment Authorization Permanent residents can live and work in the United States indefinitely, but they cannot vote in federal, state, or local elections.2U.S. Citizenship and Immigration Services. Rights and Responsibilities of a Green Card Holder (Permanent Resident)
The status itself doesn’t expire, though most Green Cards are valid for 10 years and need renewal. Some older cards issued before the current design have no expiration date and remain valid.1U.S. Citizenship and Immigration Services. 13.1 List A Documents That Establish Identity and Employment Authorization When an officer writes “RA” on a report, they’re recording immigration classification: permanent resident, as distinct from citizen, temporary visa holder, or undocumented.
Other Departmental Uses
Some agencies use “RA” to label a Reporting Area or Response Area, a geographic patrol zone used for dispatching units and tallying crime statistics. You might run across it in published crime data, where incidents are grouped by area number to show patterns across neighborhoods. A few departments also use “RA” as a job-title abbreviation for Records Assistant, a civilian role managing police files. Both are internal shorthand and rarely surface outside departmental documents.
Why the Resident Alien Designation Matters
The booking-sheet version of RA is the one that carries real-world weight, because it ties a police encounter to immigration consequences.
Carrying the Card Is Required by Federal Law
Every non-citizen age 18 and older must carry their registration card at all times. Not having it on you is a federal misdemeanor punishable by a fine of up to $100, up to 30 days in jail, or both.3Office of the Law Revision Counsel. 8 USC 1304 – Forms for Registration and Fingerprinting Federal prosecutors rarely bring that charge on its own, but the obligation is real, and it can complicate a police encounter when identity is hard to verify without the card.
How Status Gets Checked
When police book someone into jail, fingerprints run automatically through federal immigration databases. If there’s a match, Immigration and Customs Enforcement is usually notified within hours and may issue a detainer asking the jail to hold the person briefly or notify ICE before release. Many jails also share booking lists with ICE or give agents access to their databases.
In a traffic stop or field encounter, officers can run your information through the National Crime Information Center, which searches an Immigration Violator File alongside other databases. A match alone isn’t enough for the officer to act on immigration grounds. The agency has to contact ICE to confirm status, and ICE directs any next step. Most local departments don’t have independent authority to enforce immigration law unless they participate in the federal 287(g) program, which lets ICE delegate certain enforcement functions to trained state and local officers under a written agreement.4Office of the Law Revision Counsel. 8 USC 1357 – Powers of Immigration Officers and Employees5U.S. Immigration and Customs Enforcement. Partner With ICE Through the 287(g) Program Even without such an agreement, officers can still ask about immigration status.
Criminal Charges Can End Permanent Resident Status
A permanent resident facing certain criminal charges can be placed in removal proceedings, and some convictions make deportation effectively automatic. Federal immigration law groups the main triggers into several categories:6Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens
- Aggravated felonies. A broad immigration-law category covering offenses such as murder, drug trafficking, firearms trafficking, money laundering over $10,000, and many theft or fraud offenses carrying sentences of at least one year. A conviction at any point after admission makes a permanent resident deportable and cuts off most forms of relief.7Legal Information Institute. Aggravated Felony – 8 USC 1101(a)(43)
- Crimes involving moral turpitude. A conviction within five years of admission for an offense carrying a possible sentence of one year or more triggers removal. Two or more such convictions at any time also qualify, even if neither individually would meet the threshold.
- Drug offenses. Nearly any drug conviction makes a permanent resident deportable. The sole exception is possession of 30 grams or less of marijuana for personal use.
- Firearms offenses. Any conviction tied to buying, selling, or possessing a firearm in violation of law.
- Domestic violence and related offenses. Convictions for domestic violence, stalking, child abuse, child neglect, and violations of protective orders.
If you’re a permanent resident facing criminal charges, the immigration consequences of a plea deal deserve as much attention as the criminal penalties themselves. A charge that looks minor in criminal court can end your ability to stay in the country, and defense attorneys who don’t practice immigration law sometimes miss that risk. Raise it yourself if your lawyer doesn’t.
Your Rights During a Police Encounter
Immigration status doesn’t change your constitutional protections. The Fifth Amendment protects you from being forced to answer questions that could incriminate you, and you can invoke that right by clearly stating you want to remain silent. The Sixth Amendment guarantees the right to an attorney in criminal proceedings.
You are not required to answer questions about your immigration status, country of birth, or how you entered the United States. You can politely decline and ask to speak with a lawyer. Officers may still ask, but refusing to answer is not itself a crime. Carry your Green Card as the law requires, and understand that handing it over doesn’t obligate you to answer anything further beyond basic identification.
