How long does USCIS have to decide my case before I can sue?

2 min read · August 18, 2026

There is no statutory deadline — but federal courts apply the six-factor TRAC test for unreasonable delay, and most successful mandamus actions are filed when an adjudication has sat 2x the published processing time without movement.

Mandamus jurisdiction exists when an agency has a clear, non-discretionary duty to act and has unreasonably failed to do so. The duty to adjudicate is non-discretionary even when the underlying decision is discretionary — USCIS must decide your case; it can deny, but it cannot sit on it forever. The vehicle is 28 U.S.C. § 1361 (mandamus) and 5 U.S.C. § 706(1) (APA "unreasonable delay").

The TRAC factors

In TRAC v. FCC, 750 F.2d 70 (D.C. Cir. 1984), the court laid out six factors that every district court uses to evaluate unreasonable delay:

1. The time agencies take must be governed by a rule of reason.
2. Where Congress provides a timetable, that is the rule of reason.
3. Human health and welfare delays are less tolerable than economic ones.
4. The effect of expediting delayed action on higher-priority agency activities.
5. The nature and extent of the interests prejudiced by delay.
6. The court need not find impropriety; bad faith is not required.

Our internal trigger

We typically open a mandamus case when:

• The case has been pending 2x the USCIS-published processing time for the form and field office;
• All RFEs have been answered and the file shows no outstanding requests;
• The client has filed a case-status inquiry, an Ombudsman request, and a congressional inquiry — exhausting the administrative ladder.

What relief looks like

We are not asking the court to grant the underlying benefit. We are asking for an order compelling USCIS to adjudicate within a date certain (typically 30–90 days). In practice, most cases settle — the U.S. Attorney's Office contacts USCIS, the case gets pulled, and a decision issues within 60 days without a formal court order.

The trap clients miss

Filing too early hurts. If processing-time data still shows the case is "within normal processing," the court will dismiss as not ripe and the client will pay filing fees and attorney time for nothing. Patience for the 2x rule is part of the strategy.

How we handle this

We pull current published processing times, calendar the 2x date, build the administrative-exhaustion record in advance, and file a tight complaint citing TRAC and the specific months of inaction. Settlements are the norm; we plan around them.
