For mandamus cases, the first step is to confirm that your delay is legally unreasonable. We collect documentation showing your full compliance with prior steps. Then we prepare a draft complaint for review. Once approved, we file it in federal court. You’ll be kept updated on every response and timeline.

After filing the mandamus complaint, we notify the government agencies involved and track their response deadline. Most cases trigger government action before the court hearing stage. If there’s no response, we push forward with court scheduling. Throughout the process, we handle all communication and filings. You’ll receive ongoing updates as your case progresses.

In a mandamus case, we handle follow-up communications with government attorneys and the court. Many agencies act quickly once a lawsuit is filed, but we’re prepared to push further if needed. If a hearing is scheduled, we manage filings and arguments. You’ll be kept fully informed and prepared at every turn. We remain your advocate throughout.

4.

After a successful mandamus result, we monitor USCIS or embassy action to ensure your case moves forward. We stay involved until a final decision is issued.

Not sure if a mandamus lawsuit is right for you? You’re not alone—many clients aren’t sure when it’s time to file or what the process involves. We’ve answered the most common questions about mandamus cases, delays, and results. If you’re dealing with a stalled USCIS or embassy case, start here. Our FAQ section gives you a clear, no-pressure introduction to this legal option.

What is a mandamus lawsuit in immigration law, and how can Nimer Law use it to challenge unreasonable delays in my case?

A mandamus lawsuit is a federal court action used to compel a government agency, like USCIS or the State Department, to make a decision on a delayed immigration application. Nimer Law files mandamus actions strategically when your case has been unreasonably delayed, forcing the agency to act without asking the court to approve or deny your application.


When should I consider filing a mandamus lawsuit for my Green Card, citizenship, or visa case, and what makes a delay “unreasonable”?

If your immigration application has been pending beyond normal processing times with no clear explanation or progress, typically for over 12 months, a mandamus lawsuit may be appropriate. Nimer Law evaluates your case history, documents the delay, and determines whether legal action is likely to result in faster adjudication.


Can filing a mandamus lawsuit hurt my immigration case or create negative consequences with USCIS or the embassy?

No, the law prohibits retaliation for filing a mandamus lawsuit. You are asserting a legal right to timely adjudication. Nimer Law ensures the complaint is respectful, well-supported, and positions you as a cooperative applicant, helping reduce risks and encouraging prompt government response.

How long does a mandamus lawsuit take, and what are the possible outcomes once it’s filed in federal court?

Mandamus lawsuits often prompt government action within 60 to 90 days, though timelines vary. The most common result is that USCIS or the consulate finally processes your case. Nimer Law closely tracks your filing, negotiates with government counsel when appropriate, and provides legal representation through all court steps until resolution.

What types of immigration cases can benefit from a writ of mandamus, and how does Nimer Law assess whether legal action is the best next step?

Mandamus can be effective in delayed I-485, N-400, I-601, or visa applications stuck in administrative processing. Nimer Law reviews your full immigration history, gathers delay evidence, and prepares a federal complaint when internal inquiries and congressional requests fail—ensuring your case moves forward after months or years of silence.
