USCIS Mandamus in the Eastern District of New York

The Eastern District of New York (EDNY) covers Brooklyn, Queens, Staten Island, Nassau County, and Suffolk County — collectively, one of the largest concentrations of first-generation immigrants in the United States. The Brooklyn Field Office, the Queens Field Office, the Holtsville Field Office, and the New York City Asylum Office all sit within or near the district's reach. The result is a steady, high-volume USCIS mandamus docket that resolves predominantly through voluntary dismissal after agency adjudication.

Judicial posture

EDNY's bench is generally receptive to mandamus claims, with a clear understanding that USCIS delays at the New York-area field offices are systemic rather than case-specific. The most frequently cited adverse EDNY precedent in practitioner advisories is N-N v. Mayorkas, 540 F. Supp. 3d 240 (E.D.N.Y. 2021), a U-visa case in which the court granted a Rule 12(b)(6) motion to dismiss on TRAC-factor grounds. But N-N is the exception rather than the rule, and the U-visa context is distinct enough that the holding does not extend cleanly to I-485, I-130, or N-400 mandamus actions.

The U.S. Attorney's Office for the Eastern District has a well-established practice of reaching out to plaintiffs' counsel within 30 to 45 days of service to discuss adjudication rather than dispositive motion practice. Most cases are resolved by USCIS adjudication well before a motion to dismiss is filed.

Form-type mix

EDNY's docket is dominated by I-485 adjustment of status, with substantial volumes of N-400 naturalization (filed under 8 U.S.C. § 1447(b)) and I-130 family petition cases. The diversity of immigrant communities served by the Brooklyn and Queens field offices means the docket also includes a meaningful share of I-589 asylum, I-751 removal of conditions, and I-765 work authorization cases.

• I-485 Adjustment of Status — the largest single category, driven by Brooklyn and Queens field office backlogs.
• N-400 Naturalization — substantial share; § 1447(b) actions following delayed interview-to-decision intervals.
• I-130 Family Petition — both standalone petitions and consular-processing hybrids.
• I-589 Asylum — the New York City Asylum Office backlog drives this category.
• I-751 Removal of Conditions — meaningful share given the size of the conditional-resident population in the district.

Estimated disposition posture

My estimate is that roughly 83% of resolved EDNY cases end in voluntary dismissal after USCIS adjudication, with about 10% dismissed on a government Rule 12 motion. The total "case-reached-a-judge" rate of about 13% is one of the lowest in the seven-district set I analyze. These figures are estimates synthesized from secondary sources — see the flagship comparison for methodology.

Strategic considerations

1. EDNY is the natural forum for petitioners residing in Brooklyn, Queens, Staten Island, Nassau, or Suffolk Counties.
2. The voluntary-dismissal posture means that even strong cases are usually mooted by USCIS adjudication before reaching motion practice. This is good for the petitioner but limits the development of favorable precedent.
3. When a case does reach a Rule 12 motion, the U-visa context (post-N-N) is higher risk than standard I-485 or N-400 claims. Practitioners with U-visa delay cases in EDNY should consider whether EDMI (post-Barrios Garcia) is a better venue where venue flexibility exists.
4. The Second Circuit's mandamus posture is generally plaintiff-favorable, which makes EDNY a reliable Rule 12 environment for most form types.

When EDNY is the right choice

EDNY is the right forum for petitioners residing in the district or those whose adjudicating USCIS office is the Brooklyn, Queens, or Holtsville Field Office. It is also a sensible choice when the petitioner has flexibility under § 1391(e) and prefers a Second Circuit forum to a D.C. or Fifth Circuit alternative.

EDNY's high voluntary-dismissal rate makes it a generally favorable venue for I-485, I-130, and N-400 mandamus actions. For U-visa cases — and only U-visa cases — EDMI may be a preferable venue if venue choice is available.
