EOIR, USCIS, ICE?? A Guide to Who Does What

USCIS – The Paperwork People (Most of the Time)

U.S. Citizenship and Immigration Services, or USCIS, is where most immigration cases begin. They handle petitions, green card applications, naturalization, work permits, DACA renewals, and most “benefits” for noncitizens. USCIS is part of the Department of Homeland Security (DHS), but they aren’t the ones enforcing the law. They’re supposed to be administering it. And crucially, USCIS officers are not judges. If your client’s case is denied here, that isn’t necessarily the end. There are often still options, including motions, appeals, or even litigation in front of a judge, just not through USCIS itself.

ICE – The Enforcers

U.S. Immigration and Customs Enforcement, better known as ICE, handles the enforcement side: detention, deportation, worksite investigations, supervision check-ins, and yes, immigration raids. They’re also under DHS, but with an entirely different set of rules and priorities. One often overlooked fact is that ICE includes the Office of the Principal Legal Advisor (OPLA). Those are the government attorneys in removal proceedings. So when you’re in immigration court, the same agency that may have detained your client is also representing the government, trying to remove them.

CBP – The Border Bosses

Customs and Border Protection, or CBP, handles inspections and entry at the U.S. border, airports, and other ports of entry. They're also part of DHS. Do you sense a theme here? They act as the frontline of immigration enforcement. Think of them as the gatekeepers. They’re deciding whether someone is allowed into the country in the first place. One key document they issue is the I-94, which tells you how long your client can legally stay in the U.S. It’s often overlooked, but the I-94 can make or break a case, especially if there's a mismatch between what's stamped and what's authorized. Always check it.

EOIR – The Court System

The Executive Office for Immigration Review, or EOIR, is the court system for immigration cases. Here’s a twist: EOIR is not under DHS, it’s part of the Department of Justice. This is where immigration judges preside over removal proceedings, asylum cases, bond hearings, and appeals through the Board of Immigration Appeals (BIA). Despite the judicial tone, EOIR judges are administrative and appointed by DOJ leadership. Also, your client doesn’t automatically end up in immigration court just because they get a denial from USCIS. EOIR only comes into play if DHS (usually ICE) initiates formal removal proceedings. That step is discretionary, which means not every denial results in a Notice to Appear (NTA).

So, how does this all fit together?

If you’re filing a marriage-based green card application, you’re working with USCIS. If your client is detained after a traffic stop, they’re likely in ICE custody. If they were turned away at the airport or held up at the border, that’s CBP’s territory. If they’re scheduled for a hearing before a judge, now you’re in EOIR’s world.

Immigration law isn’t linear. It’s a maze of overlapping jurisdictions, discretionary decisions, and yes, a ton of acronyms. But once you get a grip on who’s who, it all becomes a lot more manageable and explaining it to your clients becomes easier, too.

The 5 Immigration Terms That Tripped Me Up Early On (and What They Mean)

In law school, we’re taught to read statutes and briefs, but no one gives us a decoder ring for immigration terms. And I don’t just mean the acronyms I mean the everyday phrases that sound intuitive... but aren’t. Here are five immigration terms that confused me early in my career and how I finally made peace with them.

1. Adjustment of Status

What I thought it meant: It sounds like you are changing your status from one thing to another, right? Like adjusting a visa or tweaking a category.

What it means: Adjustment of Status (AOS) is applying for a green card from inside the United States. It’s how someone moves from nonimmigrant (temporary) status to lawful permanent resident (LPR) without leaving the country.

Why it matters in practice: It’s a huge distinction. If your client is eligible for AOS, they don’t have to do consular processing abroad. But not everyone qualifies. Prior unlawful presence, unauthorized entry, or certain visa statuses can block them from adjusting. Knowing the difference between AOS and consular processing can change the case strategy.

2. Advance Parole

What I thought it meant: The word “parole” just made me think of prison. I assumed it meant some kind of probation or enforcement action.

What it actually means: Advance Parole is a travel document that lets someone with a pending green card application (or other specific applications) leave the U.S. and return without abandoning their case.

Why it matters in practice: Without Advance Parole, a client could leave the country to visit family and not be allowed back in, effectively killing their case. This term sounds punitive, but it’s protective. Now I double-check for travel plans during every AOS consultation.

3. Inadmissibility

What I thought it meant: It sounded like a courtroom objection: “Objection, your honor, inadmissible!” I thought it applied only to evidence.

What it actually means: In immigration, inadmissibility refers to reasons someone can be barred from entering or staying in the U.S. Things like criminal history, health issues, prior immigration violations, or public charge concerns.

Why it matters in practice: This term comes up everywhere - visas, green cards, waivers, adjustment, consular processing. It’s not just about being let in; it can affect someone already here. Understanding inadmissibility grounds early can help you avoid avoidable denials.

4. Entry Without Inspection (EWI)

What I thought it meant: I thought it was the same as “illegal entry,” which I now avoid saying. I assumed it meant sneaking in through the desert or crossing a river.

What it actually means: EWI means entering the U.S. without presenting yourself to an immigration officer for inspection. That could be by crossing the border somewhere unofficial, but it can also apply to people who just never went through inspection at a port of entry.

Why it matters in practice: Clients who entered EWI face significant hurdles. Many aren’t eligible for Adjustment of Status and need special relief like waivers or must leave and risk triggering bars. Understanding this distinction shapes everything, from relief options to what you promise at consults.

5. Immediate Relative

What I thought it meant: I assumed it meant “close family”, like parents, kids, spouses, siblings, grandparents.

What it actually means: “Immediate relative” is a specific category in immigration law: spouses, unmarried children under 21, and parents of U.S. citizens over 21. That’s it. No siblings. No cousins. 

Why it matters in practice: Unlike other family categories, this group of individuals has no visa limits or waiting periods. Clients often assume their sibling qualifies as “immediate,” they’re crushed when they learn it’s a decades-long wait. Getting this one right at the intake meeting saves heartache and confusion.

There are dozens more where these came from, but these five were turning points in how I began thinking like an immigration lawyer. I learned quickly that language isn’t just different in this field; it’s the whole game.
