Should I file a FOIA, a congressional inquiry, or a mandamus?
Each tool answers a different question — FOIA tells you what is in the file, a congressional inquiry pushes the case internally, and mandamus is the lawsuit that forces a decision when the first two failed.
These three tools look similar to clients but solve completely different problems. Choosing the wrong one wastes months.
FOIA — what is in the A-file
A Freedom of Information Act request to USCIS, ICE, or CBP returns the agency's own file. Use it when you need to see what the government sees — old applications, RFEs not in the client's copy, sworn statements, NCIC hits, prior counsel's submissions. FOIA is essential before naturalization, asylum, post-removal, or any case with a long immigration history.
Congressional inquiry — internal nudge
A constituent's congressional office can submit a liaison inquiry to USCIS. This puts the case in a queue that gets an answer, usually within 30–60 days. The answer is typically "still processing" — but it sometimes triggers movement, especially where the case has been miscategorized. Free, fast, and the right first step on any delay under 1.5x normal time.
Ombudsman request (Form DHS-7001)
The CIS Ombudsman is an internal advocate inside DHS. The Ombudsman request is more substantive than a congressional inquiry and is the right tool when the client meets specific "case assistance" criteria — particularly where USCIS error is visible in the receipt or biometrics scheduling.
Mandamus — the lawsuit
Mandamus is filed in federal district court under 28 U.S.C. § 1361 and 5 U.S.C. § 706(1). It is the right tool when the case is well over 2x published times, all administrative avenues have failed, and the delay is causing concrete harm. It costs a court filing fee plus attorney time; the upside is that it almost always produces a decision within 60–90 days.
Our typical sequence
- FOIA at engagement if the file is uncertain.
- Case-status inquiry + congressional inquiry at 1x processing time.
- Ombudsman request at 1.5x processing time.
- Mandamus at 2x processing time with the prior steps in evidence.
This ladder makes the eventual mandamus complaint very strong — the record already shows every internal channel was tried and exhausted.
Frequently asked questions
What documents prove that my marriage is real?
You can submit evidence that you share a life with your partner, such as joint bank accounts, rental contracts in both names, and photos of your daily life. It is important to show that your relationship is genuine and that both have plans for a common future.
What happens if my sponsor does not earn enough?
If the spouse requesting residency does not have sufficient income, you can seek a joint sponsor. This person must be a citizen or resident and accept financial responsibility to help you meet the legal requirements for minimum income.
Must I attend an interview with an immigration officer?
In most marriage residency cases, the immigration service requires a personal interview with both spouses. During this appointment, an officer will ask questions about your relationship and your history as a couple to confirm the validity of the marriage.
Can I work while waiting for my green card?
You can apply for a work permit at the same time you send your marriage residency application. If the government approves your permit request, you will receive a card that allows you to work legally while the main case remains under review.
