Filing the complaint feels like the end of a long road, but it is the beginning of a short, structured process. The first 60 days after service are usually the most eventful, and many cases are resolved in that window. This guide describes what typically happens after a delay lawsuit is filed, what you should be doing while you wait, and how to think about each possible ending.
The first weeks: service and the clock
After filing, the plaintiff serves the defendants under the federal rules. When the U.S. Attorney is served, the government’s time to answer or move to dismiss generally runs for 60 days. A calendar entry for that date, and for the deadline to file proof of service, helps avoid missed steps.
During this period the case is usually quiet. The court may issue a standard scheduling order, and a judge’s standing order may require the parties to confer or file a status report. Read every order that arrives, since judges differ in what they require.
What USCIS often does
In many delay suits, USCIS reviews the file once the complaint arrives and decides the case within the response period. Government lawyers also contact the agency to ask for the status. The result may be an approval, a denial, a request for evidence or a scheduled interview.
That is why a well-timed suit is often described as a way to get the agency’s attention. But it is important to understand that a decision is not necessarily an approval, and the plaintiff should be prepared for either outcome before filing.
Extensions and stays
The government frequently asks for more time, sometimes for 30 to 90 days, saying the agency needs it to complete a review. It may also ask the court to stay the case while the agency works. Judges commonly grant a first request, particularly when it is made early and with a reason.
Plaintiffs can oppose repeated or open-ended requests, and judges may ask for a status report, a firm date or a short update. Cooperation is often worthwhile when the agency is making real progress, but a plaintiff should not accept an indefinite pause.
The motion to dismiss and the opposition
If the government files a motion to dismiss, the plaintiff generally has a short period, set by local rules, to respond. The response should address each argument, cite the statute that creates the duty and attach evidence of the timeline and harm. A judge may rule on the papers, hold a hearing or ask for further briefing.
A ruling may deny the motion, grant it in part or dismiss the case. If the motion is denied, the government must answer, and the case moves toward a short schedule. If it is granted, the judge usually states the reasons, and a lawyer can discuss whether to amend or appeal.
When the agency decides: dismissal and closing out
If USCIS acts, the usual next step is that the parties file a stipulation of dismissal, or the plaintiff voluntarily dismisses the case. Federal Rule of Civil Procedure 41 governs these dismissals. Formal dismissal closes the file, so no case is left pending once the dispute is over.
Before agreeing to dismiss, confirm the decision in writing. Check the approval notice or denial and ask your lawyer whether any fees or costs should be addressed in the stipulation. The next article discusses fee recovery.
If the decision is a denial
A denial ends the delay claim but not necessarily the case. A denial normally comes with notice of appeal or review options, and deadlines can be short. Possible steps include an administrative appeal or motion to reopen, a new application or a separate lawsuit challenging the decision under the APA.
A delay suit is not the vehicle for challenging a denial on the merits, so a new strategy is needed. Speak with an attorney right away about deadlines, and keep every notice you receive.
What the plaintiff should do in the meantime
Several practical steps help while the case is pending:
- Keep your mailing address and contact information current with USCIS, the court and your lawyer.
- Respond quickly to any request for evidence, interview notice or biometrics appointment.
- Do not ignore court orders or communications from government lawyers.
- Keep a record of every notice and the date you receive it.
- Avoid travel or other steps that could affect eligibility without first checking with your lawyer.
Possible endings at a glance
Most delay suits end in one of a few ways. The agency decides and the case is dismissed as moot. The parties agree on a timetable and the court approves it. The court orders the agency to act within a set period. Or the court dismisses the case because the delay is not unreasonable or the claim is barred.
A typical case moves quickly, often within a few months, but timing varies with the court and the complexity of the file. A lawyer who knows the judge and the local government attorneys can give a realistic estimate once the case is filed.
For examples of how courts have ruled, see notable mandamus cases. What happens after filing also depends on the court; compare mandamus in the Southern District of New York with mandamus in the Eastern District of New York.
Frequently asked questions
Can I still contact USCIS after the lawsuit is filed? You should respond to any notice you receive, such as a request for evidence, interview or biometrics appointment. Discuss other communications with your lawyer so that nothing undermines the case.
What if USCIS requests more evidence? Respond completely and on time, and tell your lawyer. A missed deadline can lead to a denial and can hurt the argument that the delay is the agency’s fault.
Will I have to attend a hearing? Most delay cases are decided on written filings and many end before a hearing. If the judge sets one, your lawyer will explain whether you need to attend.
What if the government misses its deadline to respond? A default against the United States is more difficult to obtain than against a private party, because courts require the plaintiff to establish a right to relief. A lawyer can advise on how to proceed.
