1. The Agencies Behind a Us Immigration Case
Immigration authority is primarily federal, but the agency, office, court, and filing location depend on the benefit, the enforcement action, and the procedural posture. Each agency owns a different part of the system.
Uscis and the Department of Labor
USCIS, a component of the Department of Homeland Security, adjudicates many immigration benefit requests, including family and employment petitions, adjustment applications, employment authorization requests, and naturalization applications. The Department of Labor administers separate employment-related processes, including PERM labor certification, prevailing wage determinations for many EB-2 and EB-3 cases, and Labor Condition Applications required for many H-1B petitions. Our US immigration law overview shows how these functions may connect.
The State Department and U.S. Consulates
Department of State consular officers adjudicate immigrant and nonimmigrant visa applications abroad. In many family- and employment-based immigrant visa cases, the National Visa Center handles fees and document processing before the case moves to the appropriate embassy or consulate, as our consular processing page explains. The State Department also publishes the monthly Visa Bulletin for numerically limited immigrant categories.
2. Benefits Vs. Court Cases: Two Tracks
The most useful distinction is between asking for a benefit and defending against removal. The two involve different agencies, rules, and venues.
Benefit Requests before Uscis
USCIS decides many benefit requests within its jurisdiction, including Form I-485 adjustment applications, employment authorization requests, and naturalization applications. An applicant who is present in the United States and independently qualifies may seek adjustment of status through USCIS or, in some proceedings, before an immigration judge, as our adjustment of status page explains. This track is administrative rather than a court proceeding.
Removal Cases before the Immigration Court
If the government seeks to remove someone, the case goes to an immigration court run by the Executive Office for Immigration Review, not to USCIS. An immigration judge hears the case, while an attorney from ICE's Office of the Principal Legal Advisor ordinarily represents the Department of Homeland Security. Our deportation defense guide covers how that track works.
| Body | What It May Handle | Where the Process Occurs |
|---|---|---|
| USCIS (DHS) | Petitions, adjustment applications, work authorization, and naturalization | Online, through a lockbox or service center, or at a field office, depending on the form |
| Department of Labor | PERM labor certification, prevailing wage determinations, and certain temporary-labor filings | Federal DOL processing systems and offices |
| Department of State | Visa processing abroad and the Visa Bulletin | The National Visa Center where applicable and a U.S. .mbassy or consulate |
| Immigration court (EOIR) | Removal proceedings and applications for relief within the court's jurisdiction | The immigration court identified in the proceeding or a later venue order |
| ICE and CBP (DHS) | ICE handles interior enforcement and detention; CBP handles inspection and admission | Detention facilities, field operations, and ports of entry |

3. Which Office or Court Handles a Staten Island Case
Staten Island is part of New York City, so its residents use the federal offices and courts that serve the area. The correct venue depends on the form or proceeding and the notices in the case.
Uscis Filing, Biometrics, and Interviews
A benefit request must be submitted through the filing method and location in the current form instructions, which may include online filing, a lockbox, or another USCIS facility. USCIS may process the case at a service center and schedule biometrics or an interview at the location stated in the appointment notice. An applicant should rely on the filing instructions and notices rather than assume that every Staten Island case goes to one local office.
Immigration Court and Enforcement
A removal case is heard by the immigration court identified in the Notice to Appear, the hearing notice, or a later venue order. A Staten Island address does not by itself establish that every proceeding will be heard at the same New York City court, particularly when detention or a venue change is involved. ICE separately carries out many enforcement and detention functions, while EOIR immigration judges decide matters within the court's jurisdiction.
4. Appeals and Who Reviews Them
A denial is not always final, but the review body depends on which office issued the decision. Sending an appeal to the wrong place wastes time.
Administrative Appeals
Some USCIS decisions are appealable to the Administrative Appeals Office, while certain family-based petition decisions fall within the jurisdiction of the Board of Immigration Appeals. Other decisions permit only a motion, no administrative appeal, or a different review procedure. The decision notice identifies whether review is available and where it must be filed.
Federal Court Review
A petition for review of a qualifying final removal order may be filed in the federal court of appeals with proper venue under the governing statute, which is often the Second Circuit when the proceedings were completed within it. Separate federal district court claims may exist in limited circumstances, though jurisdiction and available relief depend on the statute, the agency action, and the type of claim. These are court cases with their own rules and deadlines.
5. Matching a Matter to the Responsible Agency
A useful first step is to identify the agency or court with current authority over the matter. The list below maps common situations to the body that handles them.
- A family petition: USCIS, with the Department of State involved if consular processing follows
- An employer-sponsored immigrant petition: USCIS, often after a Department of Labor process where required
- An immigrant visa application abroad: the National Visa Center where applicable and a U.S. .mbassy or consulate
- An adjustment application within USCIS jurisdiction: USCIS
- A filed Notice to Appear and removal proceeding: the EOIR immigration court identified in the case record
- An adverse decision: the review body and procedure stated in the decision notice
6. Frequently Asked Questions
What is the difference between USCIS and immigration court?
USCIS is an administrative agency that decides benefit requests such as petitions, green cards, and naturalization. An immigration court, run by EOIR, decides whether a person should be removed and whether relief is available. A case may involve both systems, because a person in removal proceedings may seek relief within the immigration judge's jurisdiction while USCIS keeps authority over certain other applications.
Where do I appeal if my case is denied?
It depends on who denied it, which is why the decision notice identifies the review body. Some USCIS decisions are appealable to the Administrative Appeals Office, certain petition decisions are reviewed by the Board of Immigration Appeals, and immigration judge decisions generally may be appealed to the Board. Judicial review of a qualifying final removal order may then be available in the appropriate federal court of appeals.
Does living in Staten Island change where my case is handled?
A Staten Island address may affect which USCIS office schedules an interview or other local appointment, but the filing instructions and agency notices control. In removal proceedings, the assigned immigration court appears in the Notice to Appear, the hearing notice, or a later venue order, and changing an address does not automatically change the court. Address updates must be submitted through the procedures required by each agency handling the matter.
7. Identifying the Responsible Agency or Court
The applicable filing instructions, receipt notice, hearing notice, and decision notice identify the agency or court handling each stage of a matter. A change of address should be reported through the separate procedures required by USCIS, EOIR, or another agency, but an address update does not by itself transfer an immigration-court case. Because office locations, filing systems, agency instructions, and review procedures may change, each submission should follow the current instructions for the specific form or proceeding.
