An immigration lawyer is an attorney who helps people obtain visas, green cards, work permits, and U.S. citizenship, and who defends people facing deportation. If you are trying to sponsor a family member, get a green card, become a citizen, apply for a work visa, seek asylum, or respond to a notice from immigration court, an immigration attorney can review your situation, tell you which options realistically apply to you, prepare your case, and represent you before the government. Immigration law is federal, complex, and unforgiving of mistakes, so getting qualified help early often matters more than in almost any other area of law.
This article is general legal information, not legal advice. Laws vary by state and situation, and reading it does not create an attorney-client relationship. For advice about your case, talk to a licensed attorney.
Immigration law also changes frequently and depends heavily on your individual facts — your country of origin, how you entered the United States, your immigration history, and any criminal record. Nothing here is a determination that you are or are not eligible for any benefit. Verify current rules at USCIS.gov and travel.state.gov, and talk to a licensed immigration attorney before you file anything or make a decision about travel.
Key Takeaways
- Immigration lawyers handle a wide range of matters: family- and employment-based green cards, marriage cases, naturalization, work visas like the H-1B, asylum and humanitarian protection, and removal (deportation) defense.
- Only a licensed attorney or a Board of Immigration Appeals (BIA)-accredited representative can legally give immigration advice for a fee. "Notarios" and "immigration consultants" cannot — and notario fraud causes serious, sometimes permanent, harm.
- Deadlines in immigration are short and frequently irreversible. Examples include the one-year filing deadline for asylum and the roughly 30-day window to appeal an immigration judge's decision. Missing one can permanently close an option.
- A Notice to Appear (NTA) or an order of removal is a legal emergency — contact an attorney immediately rather than trying to handle immigration court alone.
- Costs vary widely by case type and location. Many immigration attorneys charge flat fees for defined applications and offer a free or low-cost initial consultation; government filing fees are separate and change often.
- Because immigration consequences can follow even minor criminal charges, anyone who is not a U.S. citizen and is facing a criminal case should talk to both a criminal defense lawyer and an immigration lawyer before accepting any plea.

What an Immigration Lawyer Does
An immigration lawyer helps people move through the U.S. immigration system, which is run by several different federal agencies and governed by statutes, regulations, and policy that shift over time. On any given case, an immigration attorney might assess which paths are available to you, choose the right strategy, prepare and file the correct applications, gather and present supporting evidence, respond to government requests, prepare you for interviews, and represent you in immigration court or on appeal.
A good immigration attorney does a few things before filing anything. First, they take a full history — how you entered, your immigration record, family relationships, employment, time in the United States, and any criminal history — because all of these can change what is possible and what is risky. Second, they identify which agency handles your matter and what that process actually requires. Third, they flag deadlines and traps, because in immigration a single misstep (filing the wrong way, traveling at the wrong time, or missing a deadline) can trigger a bar, a denial, or removal.
From there, the work depends on the case: assembling a marriage-based green card packet, filing a naturalization application, sponsoring a worker for an H-1B, building an asylum claim, requesting a bond hearing for a detained relative, or arguing a defense to removal in immigration court.

Which Government Agency Handles Your Case?
One of the most confusing parts of immigration is that several different federal agencies are involved, and they do very different things. Knowing which one you are dealing with helps you understand the process and explain your situation to a lawyer.
| Agency | What it does |
|---|---|
| USCIS (U.S. Citizenship and Immigration Services) | Adjudicates most applications filed inside the U.S. — green cards, work permits (EADs), naturalization, family petitions, asylum applications, and more. |
| Department of State (DOS) | Handles consular processing at U.S. embassies and consulates abroad, the National Visa Center, and publishes the monthly Visa Bulletin. |
| CBP (Customs and Border Protection) | Inspects travelers at ports of entry, controls admission, and maintains I-94 arrival/departure records. |
| ICE (Immigration and Customs Enforcement) | Handles interior enforcement, arrest, detention, and removal; ICE attorneys represent the government in immigration court. |
| EOIR / DOJ (Executive Office for Immigration Review) | Runs the immigration courts (immigration judges) and the Board of Immigration Appeals (BIA). |
| Federal courts of appeals | Review certain immigration decisions after administrative remedies are exhausted. |
Most "benefit" cases (a green card, citizenship, a work permit) go through USCIS or, if you are abroad, the State Department. Most "enforcement" cases (deportation) go through ICE and the immigration courts under EOIR. Many real cases touch more than one agency.

Common Cases Immigration Lawyers Handle
Immigration practice is broad, but most people reach out about one of a handful of needs.
Green Cards (Lawful Permanent Residence)
A green card makes you a lawful permanent resident, with the right to live and work in the United States permanently. There are several pathways — through a qualifying family member, through an employer, through asylum or refugee status, through the diversity visa lottery, or through humanitarian programs such as VAWA, the U visa, or the T visa. Which path fits depends on your relationships, work, and history. Our guide to how to get a green card and every pathway explained walks through the options in detail.
Marriage-Based Green Cards
Marrying a U.S. citizen or permanent resident can create eligibility for a green card, but it does not automatically make you a resident — there are petitions to file, background checks, usually an interview, and (for newer marriages) a conditional two-year card whose conditions must later be removed. USCIS reviews these cases carefully to confirm the marriage is genuine. For a full walkthrough, see our step-by-step guide to sponsoring your spouse for a marriage green card. Because these cases overlap with divorce and domestic-relations issues, a family law attorney is sometimes involved too.
U.S. Citizenship and Naturalization
Most lawful permanent residents can apply to naturalize after five years (or three years if married to and living with a U.S. citizen), if they meet continuous-residence, physical-presence, good-moral-character, and English and civics testing requirements. The counting of time is specific, and extended travel can break the clock. Our article on how to apply for U.S. citizenship and the naturalization process explains each step.
Work Visas (Including the H-1B)
Employers sponsor foreign workers through nonimmigrant categories like the H-1B (specialty occupations), L-1 (intracompany transfers), O-1 (extraordinary ability), and TN (for certain Canadian and Mexican professionals). The H-1B is subject to an annual cap and, for cap-subject petitions, a lottery, and it involves the Department of Labor as well as USCIS. Our explainer on H-1B requirements, the cap, and how the lottery works covers the details. Because employer-sponsored visas overlap with workplace rights, an employment lawyer is sometimes part of the picture.
Asylum and Humanitarian Protection
People who fear persecution in their home country on account of race, religion, nationality, political opinion, or membership in a particular social group may qualify for asylum. There is generally a strict one-year filing deadline from the date of last arrival, with narrow exceptions, and claims are highly fact-specific. Our guide to how to apply for asylum in the United States explains the affirmative and defensive paths, plus related protections like withholding of removal and protection under the Convention Against Torture.
Removal (Deportation) Defense
If you have received a Notice to Appear or an order of removal, you are in or facing immigration court proceedings — and that is a legal emergency. Depending on your facts, defenses may include asylum, withholding of removal, cancellation of removal, adjustment of status, or others, plus bond hearings if you are detained and appeals to the BIA. This is not something to handle alone; representation makes a measurable difference in outcomes.
Step-by-Step: How to Find and Hire an Immigration Lawyer
- Identify what you actually need. Are you sponsoring a relative, applying for citizenship, seeking a work visa, asking for asylum, or fighting removal? The category determines which attorneys are the right fit.
- Confirm the person is a licensed attorney or an accredited representative. This is the single most important step. Look up the lawyer on the state bar website where they are licensed, or confirm that an "accredited representative" is recognized by the Department of Justice (EOIR) and working through a recognized nonprofit.
- Use trustworthy sources to build a shortlist. Our directory of immigration lawyers and our immigration attorney matching tool are good starting points; you can also check the American Immigration Lawyers Association (AILA) lawyer search and nonprofit legal aid organizations.
- Ask about relevant experience. Immigration is broad; an attorney who handles employment visas all day may not be the right person for an asylum or removal case, and vice versa. Ask how many matters like yours they have handled.
- Schedule a consultation. Many attorneys offer a free or low-cost initial consultation. Bring every notice, letter, and form you have received, your travel history, and a brief timeline of events.
- Get the fee arrangement in writing. Understand the flat fee or hourly rate, what is and is not included, and that government filing fees are separate.
- Make sure you can communicate. If you are more comfortable in another language, confirm the office can serve you in that language. Spanish-language and multilingual immigration practices are common.
- Sign a written retainer agreement. A legitimate attorney provides one. Be wary of anyone who takes your money without it.
Documents to Bring to Your First Meeting
| Document or item | Why it helps |
|---|---|
| Passports and any prior visas | Establishes identity, entries, and travel history |
| I-94 arrival/departure record(s) | Shows authorized periods of stay (different from a visa's expiration date) |
| Any current immigration card (green card, EAD) | Shows current status and expiration |
| Every USCIS or court notice, RFE, or letter you have received | Lets the attorney see deadlines and the posture of your case |
| Marriage, birth, and divorce certificates | Needed for family-based and many other cases |
| Records of all entries and exits / travel history | Affects continuous residence, abandonment, and unlawful presence |
| Any criminal records (arrests, charges, dispositions) | Even minor matters can have major immigration consequences |
| A short written timeline of key dates and events | Helps the attorney spot deadlines and eligibility quickly |
Bring originals when you can, plus copies. If you do not have a document, bring whatever you have — the attorney can advise on how to obtain the rest.
Important Deadlines
Deadlines in immigration are unusually strict, and missing one can permanently close an option. The specific dates depend on your case and the rules in effect, so treat these as general flags and verify the exact deadline on your own notice and with an attorney immediately:
- Asylum: generally must be filed within one year of your last arrival in the United States, with only narrow exceptions.
- Appealing an immigration judge's decision to the BIA: generally about 30 days from the decision.
- Responding to a Request for Evidence (RFE) or Notice of Intent to Deny (NOID): the deadline is stated on the notice itself and must be met; a late or incomplete response can lead to denial.
- Removing conditions on a marriage-based green card: generally during the 90-day window before the conditional card's second anniversary.
- Reporting an address change to USCIS: generally within 10 days of moving — and if you are in removal proceedings, you must also update the immigration court, because a missed hearing notice can lead to an in absentia removal order.
Because times and rules fluctuate, confirm anything time-sensitive against current USCIS and EOIR guidance and with a licensed attorney right away.
Common Mistakes to Avoid
- Paying a "notario" or "immigration consultant." In many countries a "notario" is a trained lawyer; in the United States a notary public has no authority to practice law. Unlicensed consultants who charge to prepare or advise on immigration cases are operating illegally, and their errors can cause denials, findings of misrepresentation, or removal.
- Traveling at the wrong time. Leaving the U.S. while an adjustment application is pending without advance parole can be treated as abandonment, and departing after accruing unlawful presence can trigger a 3-year or 10-year bar.
- Assuming an overstay or violation can be "waited out." Unlawful presence and bars are complex and can be triggered by departure; this rarely resolves on its own.
- Accepting a criminal plea without immigration advice. Immigration definitions of crimes differ from criminal law, and even a misdemeanor can be deportable.
- Ignoring a court date or a notice. Missing an immigration court hearing can result in an in absentia order of removal that is very hard to undo.
- Relying on outdated forms, fees, or processing times. These change often — always verify the current edition and fee at USCIS.gov before filing.
When to Contact an Immigration Lawyer
You do not need to be certain you qualify for something to call a lawyer — assessing that is the lawyer's job. Reach out promptly if any of these apply:
- You received a Notice to Appear, an order of removal, or any immigration court notice — this is urgent.
- A family member has been detained by ICE — an attorney can help locate them and seek a bond hearing.
- You want to sponsor a spouse, child, parent, or other relative for a green card.
- You are ready to apply for citizenship and want to confirm your timing and eligibility.
- You or an employer needs a work visa, or you are changing employers on an existing work visa.
- You fear returning to your home country and may have an asylum or other protection claim — the one-year asylum deadline makes early advice important.
- You received an RFE, NOID, or denial from USCIS.
- You are not a U.S. citizen and are facing any criminal charge — talk to an immigration lawyer and a criminal defense attorney before any plea.
- You have a prior removal, an overstay, or a possible ground of inadmissibility and want to understand your options and any available waivers.
Costs and Fees
Immigration legal costs vary widely by case type, complexity, and location, so treat any figure you see online as a rough guide rather than a quote. A few general points:
- Attorney fees and government fees are separate. The lawyer's fee pays for their work; USCIS, the State Department, and other agencies charge their own filing fees that change periodically. Always verify current government fees at USCIS.gov.
- Flat fees are common for clearly defined applications (for example, a naturalization filing or a family petition), while hourly billing is more typical for complex litigation such as contested removal cases.
- Free or reduced-cost help may be available. Nonprofit legal aid organizations, law school immigration clinics, and DOJ-recognized organizations with accredited representatives serve people who cannot afford private counsel. Be cautious of anyone promising guaranteed results — no one can guarantee an immigration outcome.
- Consultations are often free or low-cost. Ask up front, and get the fee structure in writing before you hire anyone.
The cost of a qualified attorney is almost always small compared to the cost of a denial, a bar, or a wrongful removal caused by a do-it-yourself mistake or a notario.
State and Local Differences
Immigration status is governed by federal law — states cannot create their own immigration statuses. But where you live still matters in practical ways:
- Field office and consulate practices vary. Interview practices, scheduling, and processing times differ by USCIS field office and by consular post.
- Immigration court backlogs vary by jurisdiction, which can affect how long a removal case takes.
- State laws affect immigrants' daily lives — driver's licenses (some states issue them regardless of status, others do not), professional licensing, in-state tuition, and access to certain state benefits all vary by state and change over time.
For any state-specific question, verify current state law and consult a licensed attorney familiar with your area.

Frequently Asked Questions
Do I really need an immigration lawyer, or can I file myself?
Some straightforward applications can be filed without a lawyer, but immigration is unusually unforgiving, and small mistakes can cause denials, bars, or removal. Cases involving any criminal history, prior immigration violations, an overstay, a denial, or removal proceedings are high-risk and should not be handled alone. At minimum, a consultation can tell you whether your situation is simple or carries hidden traps.
What is the difference between an immigration lawyer and a "notario"?
A licensed immigration lawyer has a law degree, is admitted to a state bar, and can legally advise and represent you. A "notario" or "immigration consultant" in the United States is usually not a lawyer and cannot legally give immigration advice or prepare your case for a fee. Only a licensed attorney or a DOJ/EOIR-accredited representative working through a recognized nonprofit may do that. Notario fraud is widespread and can cause serious, lasting harm.
How much does an immigration lawyer cost?
It depends heavily on the case type, complexity, and location, so there is no single answer. Many attorneys charge flat fees for defined applications and bill hourly for complex litigation like removal defense. Government filing fees are separate and change periodically — verify them at USCIS.gov. Ask for the full fee structure in writing before hiring anyone, and consider nonprofit legal aid if cost is a barrier.
Will a criminal charge affect my immigration status?
It can — significantly. Immigration law defines crimes differently from criminal law, and even a misdemeanor can be a deportable offense or a ground of inadmissibility in some situations. If you are not a U.S. citizen and are facing any criminal charge, talk to both an immigration attorney and a criminal defense lawyer before accepting any plea.
What should I do if I or a family member received a deportation notice?
Treat it as an emergency and contact an immigration attorney immediately. A Notice to Appear starts removal proceedings, and missing a court date can lead to a removal order issued without you present. If a relative is detained, ICE maintains an online detainee locator, and an attorney can help find the person and seek a bond hearing for their release while the case is pending.
How long do immigration cases take?
Processing times vary enormously by case type, the agency involved, your local field office, and overall demand. Some cases resolve in months; others take years, especially in oversubscribed visa categories tied to the Visa Bulletin or in backlogged immigration courts. Check current USCIS processing times at USCIS.gov rather than relying on estimates in articles, because times fluctuate significantly.
Can an immigration lawyer guarantee I will get my green card or visa?
No. No honest attorney can guarantee an immigration outcome, because eligibility is fact-specific and many benefits are discretionary even when you meet the legal requirements. Be very cautious of anyone who promises results. A good lawyer improves your odds by choosing the right strategy, avoiding mistakes, and presenting your case well — not by guaranteeing it.
How do I check whether an immigration attorney is legitimate?
Look the person up on the website of the state bar where they say they are licensed, and confirm they are in good standing. For accredited representatives, confirm they appear on the Department of Justice (EOIR) list of recognized organizations and accredited representatives. If someone resists telling you where they are licensed or refuses to provide a written agreement, that is a warning sign.
