How much does a mandamus lawsuit against USCIS cost?
Last updated 2026-10-16 · General information, not legal advice
You pay $3,500, flat. Attorney fees, the court's filing fee and certified-mail service costs are all included — through the government's response there is no second bill. Most cases get a decision inside that window and $3,500 is all those clients pay. After the response, whether to continue is your decision; work that continues is $400 an hour, quoted in writing and begun only with your approval. If you know someone else in the same position, file together and you each take $200 off: $3,300 each.
This page exists because the industry mostly will not quote. Search what a mandamus suit costs and you will page through "call us for a consultation" several times before anyone gives you a number. Below is what the fee buys, what it does not, and what to do before spending it.
What the $3,500 covers
Intake through the government's response:
- Guided intake that gets your documents together
- Venue analysis — which federal district court your case belongs in
- Attorney-drafted complaint
- Filing in the federal district court
- Certified-mail service on the defendants
- Status tracking throughout
Attorney fees, the court's filing fee and service costs are all three inside that $3,500. People often ask what the court charges on top — nothing on top. That part is already counted in.
The signed engagement agreement governs: this page is the price, the agreement is the scope.
After the government responds: what costs nothing, and what costs more
Once the complaint is served, the government has 60 days to respond under Fed. R. Civ. P. 12(a)(2), the answer period the rules give the United States as a defendant. The $3,500 runs to that response.
Whether anything more is owed after it turns on one thing, and that thing is yours to decide: closing the case costs nothing; continuing to litigate is what costs. The government's response sets out your options, and no response on its own creates a charge.
These cost nothing more
- The government decides, whether that is an approval or a denial. A decision is what mandamus asks for, so once it arrives the suit has done its job and we close it out. That step is not billed.
- The government asks for 30 to 60 more days. In practice we agree once and keep waiting for the decision, with the new deadline tracked. Waiting is not billed.
- You choose to close the case, at any point. That includes after an interview notice or an RFE, and after a motion to dismiss. Decide not to press on and the suit is dismissed with nothing further to pay.
Only this costs more
You choose to keep the suit open and press on. That is the only thing billed at $400 an hour, and in practice it comes up in two places:
- The government moves to dismiss. It is litigating rather than resolving the case, usually arguing that the pace of adjudication is not something a court may review. Holding your ground means writing a brief in response, which is real litigation.
- The government sends an interview notice or an RFE and you want the suit kept open as pressure. The case is moving, but there is still no final decision, and keeping the suit alive means there is more work to do. Closing it out instead, as above, costs nothing.
Neither starts on its own. We first put the government's argument, where it leaves your case, and the hours we expect in writing, and we begin only once you have approved it. Decline, and we close the case out under the rule above with nothing further to pay.
| What the government does | Your options, and what each costs |
|---|---|
| Approves the application | Dismiss and close the case — nothing more to pay |
| Denies the application | Dismiss and close the case — nothing more to pay. Appealing or moving to reopen the denial itself is separate work, quoted separately |
| Schedules an interview | 1. Dismiss and close — nothing more to pay 2. Keep the suit open through the interview — $400 an hour |
| Issues an RFE | 1. Dismiss and close — nothing more to pay 2. Keep the suit open after you respond — $400 an hour |
| Asks for 30 to 60 more days | Agree once and keep waiting for the decision — nothing more to pay |
| Moves to dismiss | 1. Dismiss and close — nothing more to pay 2. Brief a response and hold your ground — $400 an hour |
The three rules for hourly work: the work and the expected hours are quoted in writing first; nothing starts without your approval, so no charge arises without your say-so in writing; and you can stop at any point, in which case the suit is dismissed with nothing further to pay.
Two other things sit outside the flat fee: relief from a denial of the underlying application (an appeal, a motion to reopen, a refiling), and other applications or other cases — the flat fee attaches to the one matter named in your agreement.
Why most firms will not publish a price
Two billing models are common for mandamus work, and both leave you unable to calculate a total before you sign.
Hourly. Nothing wrong with it in principle, but the result is that you do not know whether the end number is $2,000 or $8,000 — and that number turns on something you do not control, which is how fast the government responds.
A "flat fee" with conditions attached. A lower headline number, with terms saying that certain events are billed separately — the government files a motion, the case needs supplemental material, some time limit passes. Those events are not rare in mandamus cases, so that "flat fee" is frequently not the final fee.
We put the boundary in the open instead: $3,500 covers the case through the government's response, we carry the timing risk for that stretch, and you know the total before you sign. If the case has to be litigated after that response, it is $400 an hour — the rate is published on this page, and the work is quoted in writing and begun only once you approve it. That is the difference from the second model above: the condition is not buried in the contract waiting for you to hit it, and nothing is charged without your say-so.
File with someone else and take $200 off each
If you know another person in the same position — a colleague, a classmate, someone from a forum — you can file together and each take $200 off once both of you have signed: $3,300 each.
Order does not matter. You can file on your own first, and if someone joins later the discount still applies — we refund the difference.
To be clear, these remain two separate cases, each with its own complaint and its own docket number. What the discount reduces is the price, not the number of lawsuits.
Three free routes to try before you spend this
This section will talk some readers out of paying, and it belongs here anyway: three channels cost nothing, and sometimes they alone get the case moving. In that case you never spend the $3,500.
- File a case inquiry — you submit it yourself on the USCIS site. It is free, and you do not need anyone to do it for you.
- Ask your member of Congress — their office has caseworkers for immigration matters, and the service is free to constituents.
- Go to the CIS Ombudsman — USCIS's own oversight office.
Also: checking your own case status on the USCIS site is always free. You can do it yourself whenever you want, and you should never pay anyone for it.
None of the three is a legal prerequisite to suing — courts generally will not turn you away for skipping them (see when a case qualifies). But they are free, and they leave a written record that the agency had its chance and did not act, which is exactly what a court weighs when deciding whether a delay is reasonable.
Whether it is worth paying
One thing first: a mandamus action produces a decision, not an approval. What a court can order is that the agency do its job within a reasonable time — not that it decide in your favour. No careful lawyer promises an outcome, and we do not either.
So "is it worth it" is really a comparison between two things.
On one side, a known cost. $3,500, paid once, with no later invoice.
On the other, the cost of continuing to wait. That part is personal and routinely underestimated — an EAD expiring, a child approaching 21, a spouse living in another country, a job offer that will not hold, a priority date that moves. Those are not legal questions. They are your own timeline.
If your wait has not yet passed the published processing time and has not reached 12 months, paying now is probably early. Run the 60-second check against your receipt date first. If you do not qualify, we will say so.
Common questions
Do I get a refund if we lose?
There is no outcome-contingent refund. The $3,500 buys the case being prepared and carried through the government's response — it does not buy a result, which as above nobody can promise.
Is there more to pay after the government responds?
One situation does: the government litigates instead of resolving the case, usually by moving to dismiss, and you decide to press on — that work is $400 an hour. A decision, an interview notice, an RFE or a request for more time carry no extra charge (the table above lists each one). Anything hourly is quoted in writing first and starts only once you approve it, and you can close the case out instead and owe nothing further.
Can I pay in instalments?
Tell us your situation before signing rather than after, and we will talk about it.
Does a consultation cost anything?
No. Tell us what is happening and we reply within 24 hours. The assessment is free and does not create an attorney-client relationship.
