If your marriage-based green card case has been pending with no meaningful update for over one year, the solution is simpler than you think. A mandamus lawsuit filed in federal court can help you with that delayed immigration case.
For most applicants filing inside the United States, the delay shows up as a long-pending Form I-485 (Adjustment of Status) based on marriage. In many 2026 marriage-based delay cases, forcing USCIS to make a decision on a long-pending I-485 with a writ of mandamus can provide huge relief for financial and family matters.
A mandamus lawsuit cannot guarantee approval, but it can push USCIS to stop sitting on the file and move the case toward a final resolution. Depending on the case, it may be filed again. When it is handled by an experienced mandamus lawyer, the process is typically more effective and the outlook is often more encouraging.

What Is a Mandamus Lawsuit?
In plain English, mandamus or a writ of mandamus means a court order that tells a government agency to do a duty it is required to do.
In immigration, this type of filing is used when a case has been pending for too long with little or no progress. Of course, a mandamus lawsuit is not a shortcut to approval. Instead, it pressures the government to act and move the case toward closure.

How to File a Mandamus Lawsuit for Immigration Delays (2025).
How Mandamus Can Help, and Where It May Not
A mandamus lawsuit can be strong and fast relief when it is filed properly.
What it can do is straightforward. It can put real pressure on the government to pick up the case, respond, and move it forward.
What it may not do is just as important. As mentioned above, mandamus is not a guarantee of a favorable result. Outcomes vary from case to case. The court is not stepping in to “approve” your green card. It is stepping in to require action.

How to Tell If a Marriage-Based Green Card Delay Is “Unreasonable”
Most people start looking into a mandamus lawsuit against USCIS after the case has been pending for over one year with no updates. In many situations, filing around the 13-month mark can make sense. At that point, a mandamus lawsuit against USCIS may be filed with a clear basis for the delay.
Processing-time clarification: Federal courts do not just look at what USCIS posts online. They look at the real-world facts of your case and whether the delay is reasonable under the circumstances, not just the published averages.
If your case is going through consular processing instead of Adjustment of Status, the path is different. Consular delays can involve different agencies and steps, and we explain them in our separate consular mandamus article: Mandamus Lawsuits for Consular Delays (221(g), NVC, Visa).
Why Your Marriage-Based I-485 May Be Delayed
Marriage-based I-485 delays are especially frustrating for couples. A long wait can delay a spouse’s ability to work, travel, and fully settle into life in the U.S.
Most delays come down to a few common issues:
Extra review for fraud prevention. Marriage-based cases can get more scrutiny. USCIS may take longer while verifying the relationship is real.
Requests for Evidence (RFE). If USCIS asks for more documents to prove the marriage is bona fide, the case can slow down while you respond and they review the response.
Background checks and internal processing. Even when a case looks straightforward, extra checks or internal routing can add time.
Interview scheduling delays. Some cases are ready, but interviews are delayed due to local office backlogs.
Mandamus Lawsuit Timeline for Marriage-Based Cases
The honest answer is that it depends on the facts of the case, but most timelines follow a familiar pattern once the lawsuit is filed and properly served:
After service, the government’s initial response is commonly due within about 60 days.
Many marriage-based cases see movement within 3 to 6 months.
Some cases move faster, sometimes as little as 1 to 2 months, depending on the situation and what was holding the file up.
Mandamus Lawsuit Cost and Fees
The federal court filing fee to start a civil case is $405 (a $350 filing fee plus a $55 administrative fee). Beyond that, the total mandamus lawsuit cost usually comes down to two buckets: service costs (serving the government correctly) and attorney fees.
For attorney fees (mandamus lawyer cost), many firms quote a flat fee, and it is common to see ranges in the $3,000 to $10,000+ range depending on complexity and urgency.
We believe in transparency. Many applicants worry that a federal lawsuit is too expensive. While costs vary based on case complexity, Gozel Law Firm typically works on a flat-fee basis.

Do You Need a Mandamus Lawyer, or Can You File Pro Se?
You can file a mandamus case pro se. Some people do. But this is still federal litigation and small mistakes can slow things down or get the case dismissed. If you are comparing a mandamus lawyer vs. filing on your own, here is the practical difference: a mandamus attorney builds the legal theory, chooses the right court, names the right defendants, and handles filing and service in a way that keeps the case moving. These cases are federal, so location matters mainly for filing logistics and the proper venue, not because the legal concept changes by city.
Benefits of a Mandamus Lawsuit for a Delayed Marriage-Based I-485
Faster movement toward a decision. A mandamus lawsuit can push USCIS to stop leaving your I-485 in limbo and take action, such as reviewing the file, issuing an update, scheduling an interview, or moving the case toward a final resolution.
It does not hurt your underlying green card case. A mandamus lawsuit does not change the eligibility rules or “tilt” the case one way or the other. It is not asking the court to approve or deny your green card. It is asking the court to require USCIS to do its job and process the application.
More accountability and less endless waiting. A mandamus lawsuit puts the delay on the record in federal court and forces USCIS to respond instead of letting the case sit indefinitely.
Common Mistakes That Slow Down a Mandamus Case
Here are some of the most common issues you may run into when you are in the process of filing a mandamus lawsuit:
Skipping basic follow-ups before filing. Before you file, confirm your dates and how far you are beyond normal processing times. Check your case status on the USCIS (or NVC) website, and gather proof of your follow-up attempts, such as service requests, congressional assistance, or ombudsman submissions. Before filing, make sure there is no simpler way to resolve the issue and that the delay is truly “unreasonable” for your case type.
Filing in the wrong court or choosing the wrong venue. People trying to file mandamus quickly sometimes skip the venue analysis. That can create delays before the case even starts moving.
Naming the wrong defendants or leaving out required parties. A mandamus petition has to be structured correctly, including who the lawsuit is actually against.
Improper service. Even if you file a writ of mandamus, the case can stall if the government is not served correctly and on time.
Treating mandamus like a form or “application.” Mandamus is not an agency form you submit to USCIS. It is a federal court filing.
Expecting a universal “mandamus rate.” There is no universal rate that applies to every case. Outcomes depend on the facts, the timeline, and what is actually causing the delay.
There is no universal “mandamus rate,” and results can vary depending on the facts of the case. That said, in our practice, based on internal case tracking, about 95% of our clients receive a response or see positive movement on their case after filing.
Hear directly from our clients who filed mandamus and saw progress:
Writ of mandamus USCIS cost
There is no USCIS “mandamus fee.” A mandamus case is a new federal civil lawsuit, so the baseline cost starts with the federal civil filing fee ($405). Beyond that, costs usually include service of process and, if you hire counsel, attorney fees.
Mandamus lawsuit attorney cost
The filing fee is $405 for a new civil action in federal district court. Total cost then depends on service costs and attorney fees if you hire a mandamus lawyer. Most firms work on a flat-fee basis. Depending on the complexity, fees typically range from $3,000 to $10,000+.
Mandamus lawsuit success rate
There is no universal “mandamus success rate.” Outcomes depend on the facts, the delay history, and what is holding the file. Mandamus and the APA are tools to compel agency action, not to guarantee an approval. In immigration delay cases, it is also common that the act of filing prompts the government to take action and the case ends without a written decision from the court. That said, in our practice, based on internal case tracking, about 95% of our clients receive a response or see positive movement on their case after filing.
Mandamus lawsuit timeline
A key “hard” timeline is the government’s response window in federal court. Under the federal rules, when the United States (or an officer/employee sued in an official capacity) is served, the response time is 60 days after service on the U.S. Attorney.
After that, the timeline varies. Many delay cases move because the government acts after the lawsuit is filed, but there is no fixed schedule that applies to every case.
Writ of mandamus example
A typical immigration example is: “USCIS has not acted on a long-pending I-485. The plaintiff asks the federal court to order USCIS to take action and adjudicate the application.”
That is consistent with what mandamus jurisdiction is used for: compelling an officer or agency to perform a duty owed.
Writ of mandamus Reddit
Reddit can be useful to see how applicants describe their experiences, but it is not a reliable source for what will happen in your case. Use it for anecdotes, not for rules or predictions.
Can you file a writ of mandamus by yourself?
Yes. You can proceed pro se in federal court, and the federal courts publish pro se forms and guidance.
The practical risk is that federal procedure is strict (venue, defendants, and service), and mistakes can delay the case or lead to dismissal.
How to file a writ of mandamus
At a high level, it usually looks like this: draft a federal complaint (often under Mandamus Act and APA theories), file it with the district court (pay the filing fee), then complete service under the federal rules for suits against the United States.
For the step-by-step breakdown, read our full process guide: How to File a Mandamus Lawsuit for Immigration Delays (2025).
How long does a writ of mandamus take?
In these cases, the government’s response deadline is usually tied to the 60-day rule after service on the U.S. attorney.
After that, the timing depends on the case. In many delayed cases, there is movement within a week or a couple of months without a final court ruling because the government takes action after the case is filed.
