Mandamus

Also called mandamus action, writ of mandamus, action in the nature of mandamus.

Mandamus is a suit in federal district court, brought under 28 U.S.C. 1361 and the Administrative Procedure Act, asking a judge to order USCIS to decide a petition it has left pending. It buys an adjudication and nothing more: the court can compel the agency to act but has no power to say what the answer must be, so the decision it forces may be a denial.

What it decides

District courts have original jurisdiction over any action in the nature of mandamus to compel a federal officer to perform a duty owed to the plaintiff, and the Administrative Procedure Act separately requires each agency to conclude a matter presented to it within a reasonable time and directs a reviewing court to compel agency action unreasonably delayed. In Norton v. Southern Utah Wilderness Alliance the Supreme Court held that this relief reaches only a discrete action the agency is required to take, and that where the manner of acting is left to the agency a court can compel it to act but has no power to specify what the action must be. The EB-5 statute names section 1361 expressly: no court may review a determination under 8 U.S.C. 1153(b)(5) until the regional center, its associated entities or the investor has exhausted all administrative appeals, so a denied petition goes to the Administrative Appeals Office before it can go to a judge. On the delay side there is nothing firmer to point to, because the Reform and Integrity Act wrote its processing goals as averages for setting the fee rather than as deadlines in any one case.

Governed by 28 U.S.C. 1361; 5 U.S.C. 555(b) and 706(1); Norton v. Southern Utah Wilderness Alliance, 542 U.S. 55, 64 to 65 (2004); 8 U.S.C. 1153(b)(5)(P), whose clause (i) creates the Administrative Appeals Office review right and whose clause (ii) bars judicial review, naming 28 U.S.C. 1361 and 1651, until administrative appeals are exhausted; EB-5 Reform and Integrity Act of 2022, Pub. L. 117-103, div. BB, sec. 106(b), for the average processing goals. The linked uscode.house.gov page carries 28 U.S.C. 1361 only; the title 5 sections and 8 U.S.C. 1153(b)(5)(P) were read on govinfo.gov, and Norton was read in the Library of Congress United States Reports scan of volume 542.

Processing timesA USCIS processing time is a figure published for a form: the number of months it took USCIS to complete 80 percent of the cases it adjudicated over the previous six months. It reports finished work rather than the position of any case still waiting, so it moves every month, and USCIS says to treat it as a reference point and not an absolute measure of how long a case will take.
Administrative Appeals OfficeThe Administrative Appeals Office, or AAO, is the USCIS body that reviews denials of EB-5 investor petitions, regional center applications and project approvals, looking at the whole record afresh rather than deferring to the officer below, and no court may take up an EB-5 determination until its review has been exhausted.
Motion to reopen or reconsiderA motion to reopen or reconsider is a request on Form I-290B, costing $800, that asks the USCIS office which made the latest decision in a case to look at it again, and it must be filed within 30 calendar days of that decision, or 33 days where the decision came by mail.
Denial and revocationDenial and revocation are the two ways USCIS refuses an EB-5 petition: a denial rejects a petition that has not established eligibility, and a revocation withdraws an approval already granted, which is why an approved EB-5 petition is never finally settled.
Immigrant Investor Program OfficeThe Immigrant Investor Program Office (IPO) is the single USCIS office that administers the EB-5 program and adjudicates its investor petitions and regional center filings. USCIS locates it in Washington, DC, not at a service center.
