USCIS Mandamus in the District of Columbia

The District of Columbia (DDC) is, by some distance, the heaviest-volume USCIS mandamus venue in the seven-district set I track. Three structural factors drive that volume: the USCIS Immigrant Investor Program Office (IPO), which adjudicates EB-5 petitions, sits in Washington; consular processing cases challenging delays at U.S. embassies and the National Visa Center are routinely venued in DDC under 28 U.S.C. § 1391(e); and the DDC bench has a deep administrative-law tradition that makes the court attractive to practitioners for complex mandamus claims.

The Da Costa environment

The single most consequential development in DDC mandamus practice in the past three years is the D.C. Circuit's 2023 decision in Da Costa v. Immigrant Investor Program Office, 80 F.4th 330 (D.C. Cir. 2023). In Da Costa, the D.C. Circuit affirmed dismissal of EB-5 delay claims and made the TRAC factors available at the motion-to-dismiss stage, rather than requiring factual development before applying them. The result: DDC judges now routinely dispose of EB-5 mandamus cases on the pleadings.

The broader implication: the DDC bench applies TRAC at the Rule 12 stage as the majority view, which raises the pleading-stage hurdle for plaintiffs in any mandamus action — not only EB-5. Petitioners who can file elsewhere often should.

Consular-processing law in DDC

Consular processing mandamus law in DDC is more mixed than the EB-5 picture. Al-Gharawy v. DHS, 617 F. Supp. 3d 1 (D.D.C. 2022), and Giliana v. Blinken, 596 F. Supp. 3d 13 (D.D.C. 2022), rejected the government's consular-nonreviewability defense and allowed mandamus actions to proceed. But subsequent decisions — including Mottahedan v. Oudkirk, 2024 WL 124750 (D.D.C. Jan. 11, 2024) — have applied the TRAC factors at the pleadings to dismiss cases the government characterized as too undeveloped to compel.

Form-type mix

DDC is the only district in the seven-district set in which EB-5 (I-526 and I-829) cases are a major share of the mandamus docket — an estimated 18% of resolved cases. Consular I-130 / I-485 hybrid cases dominate the rest of the docket, with smaller shares for N-400, I-765, I-589, and other form types.

• I-130 / consular processing — the largest category in DDC, driven by venue under § 1391(e) for matters involving Department of State delays.
• EB-5 (I-526 / I-829) — disproportionately large share because IPO is in D.C.; Da Costa makes these cases the hardest to litigate.
• I-485 Adjustment of Status — smaller share than in EDNY or SDTX but still meaningful.
• I-589 Asylum — meaningful share, particularly for cases involving headquarters-level review.
• I-751 Removal of Conditions — smaller share.

Estimated disposition posture

My estimate is that roughly 68% of resolved DDC cases end in voluntary dismissal after USCIS adjudication — the lowest rate in the seven-district set. About 22% are dismissed on a government Rule 12 motion, tied with SDTX for the highest MTD rate. The total "case-reached-a-judge" rate of about 27% reflects the DDC bench's willingness to engage TRAC on the pleadings. These figures are estimates synthesized from secondary sources — see the flagship comparison for methodology.

Strategic considerations

1. DDC is the appropriate (and often only) forum for cases challenging USCIS conduct that occurs in Washington — most importantly, IPO adjudication of EB-5 petitions.
2. For consular-processing cases venued in DDC under § 1391(e), the choice between DDC and the petitioner's home district often comes down to whether the consular post is the only source of the delay or whether USCIS has independent culpability.
3. Petitions filed in DDC should be drafted with a direct response to Da Costa's TRAC-at-the-pleadings logic. Pre-emptive distinction of the case from Da Costa's facts is essential.
4. Judge assignment in DDC matters substantially. Several judges have written extensively on the TRAC factors in the consular-processing context, and assignment to one of them can materially shape the case's trajectory.

When DDC is the right choice

DDC is the right forum for EB-5 cases (where it is effectively the only forum because of IPO venue), for consular-processing matters in which the State Department's National Visa Center or a particular embassy is the source of the delay, and for cases that require the development of D.C. Circuit precedent. For routine I-485, N-400, or I-130 cases where the petitioner has venue flexibility, a 2nd or 6th Circuit district is usually preferable.
