K-3 Mandamus
Class Action:
The Case After
USCIS's May 2026 Memo

On May 21, 2026, U.S. Citizenship and Immigration Services issued Policy Memorandum PM-602-0199, a sweeping reframe of how the agency views adjustment of status. The memo's title states its thesis: adjustment is "a Matter of Discretion and Administrative Grace, and an Extraordinary Relief that Permits Applicants to Dispense with the Ordinary Consular Visa Process." The memo treats consular processing as the default, the normal, the ordinary — and adjustment as an exception that must be earned through unusual equities.

Read together with what is actually happening at the agency, the memo creates a structural contradiction so sharp it almost writes the class-action complaint by itself.

This page lays out the legal theory for a class action mandamus suit to compel USCIS and the National Visa Center to adjudicate Form I-129F petitions filed for K-3 status, on the merits, to consular issuance. It explains why the May 2026 memo is the doctrinal hinge that makes the case viable now in a way it has not been for fifteen years. It is offered as an analysis, not a settled litigation plan — but the conditions for filing have changed materially as of May 21, 2026, and that change deserves serious examination.

The K-3 visa, in one paragraph

The K-3 nonimmigrant visa was created by the Legal Immigration Family Equity Act of 2000 (the "LIFE Act") and codified at INA § 101(a)(15)(K)(ii). Its purpose is direct: when a U.S. citizen petitioner files Form I-130 on behalf of their foreign spouse, and that I-130 is still pending, the spouse may obtain a K-3 nonimmigrant visa at a U.S. consulate abroad and enter the United States to wait with their family while the immigrant petition processes. Congress designed it as a humanitarian bridge — a way to keep married couples together during the long months between petition filing and immigrant visa issuance. The U.S. citizen files Form I-129F for the K-3, USCIS adjudicates it, the National Visa Center forwards the approved petition to the consulate, the consulate issues the K-3 visa, the spouse enters and lives with their U.S. citizen partner while the I-130 finishes processing.

That is the system Congress built. In 2026, it is almost entirely dormant.

Why K-3 visas are no longer issued

The reason has nothing to do with the statute and everything to do with an unwritten operational practice that NVC and USCIS have followed for roughly fifteen years.

When an I-130 and an I-129F-for-K-3 are both filed by the same petitioner on behalf of the same beneficiary, both petitions move through USCIS adjudication in parallel. Whichever is approved first is forwarded to the National Visa Center. Under longstanding Department of State and USCIS practice, if the I-130 reaches NVC before the I-129F is approved and forwarded — or if both arrive at NVC together — NVC administratively closes the K-3 case on the theory that the K-3 visa has become "unnecessary" because the immigrant visa is now available.

The rationale made some sense in 2010. I-130 processing times in that era were short. The premise was that a K-3 issued only weeks before the immigrant visa would itself be available added little value and burdened consular resources. Better, the agencies reasoned, to just process the immigrant visa.

That premise no longer holds. In 2026, I-130 processing for spouses of U.S. citizens routinely runs 14 to 24 months at USCIS. Add NVC processing (3 to 6 months) and consular interview scheduling backlogs (now another 8 to 18 months at many posts), and the cumulative timeline from I-130 filing to immigrant visa issuance commonly reaches 28 to 36 months. The K-3 bridge that Congress designed to spare families exactly this separation has been administratively closed off, while the consular processing wait that K-3 was meant to mitigate has become longer than ever.

Until May 21, 2026, the agencies could at least say: yes, the K-3 path is essentially closed, but adjustment of status inside the United States is available as an alternative for many spouses. That defense is now gone. The May 2026 memo has expressly disfavored adjustment, elevated "failure to depart as expected" to an affirmative adverse discretionary factor, and instructed officers to view adjustment as extraordinary relief that should not "supersede the regular consular visa-issuing process." The agency has now closed off both paths from the same population at the same time.

The statutory text the agencies are working around

The statute is short and the relevant operative language is unambiguous. INA § 101(a)(15)(K)(ii) defines K-3 nonimmigrants as the foreign spouse of a U.S. citizen with respect to whom the citizen "has filed a petition under section 204 for the alien spouse" — a pending I-130 — who "seeks to enter the United States to await the approval of such petition and the availability to such alien of an immigrant visa."

Three things follow from this language that the closure practice does not adequately address.

First, the statute conditions K-3 eligibility on a pending I-130, not on the I-130's adjudicative status remaining pending at every later step. Once the K-3 eligibility moment has crystallized — when the I-129F is filed at a time when an I-130 is pending — nothing in the statutory text authorizes the agencies to undo that eligibility because the I-130 is later approved. The closure practice effectively reads a "still pending at every subsequent moment" condition into a statute that says no such thing.

Second, the statute's stated purpose is to allow the spouse to "await the approval" of the I-130 inside the United States. The closure practice flips this on its head: it treats I-130 approval as the trigger for terminating, not commencing, the relief Congress promised. The very event the statute identifies as the K-3 holder's destination becomes, in operational practice, the event that closes the K-3 door.

Third, no published regulation requires closure. Closure rests on internal Department of State and USCIS operational guidance — a Foreign Affairs Manual entry and informal USCIS practice — not on a notice-and-comment regulation, and certainly not on any statutory command. That posture matters for both the APA arbitrary-and-capricious analysis and the post-Loper Bright question of how much deference, if any, the closure practice is owed.

Why the May 2026 memo changes the legal calculus

The closure practice has been criticized for years. What is different now is that USCIS has, in writing, declared the policy premise on which the closure practice's only defensible justification rested.

The defensible justification for closure was always: "the K-3 is unnecessary because the beneficiary will obtain LPR status either through consular processing of the immigrant visa or through adjustment of status inside the United States." That second alternative — adjustment — has now been formally reclassified by the agency itself as "extraordinary relief" disfavored as a general matter, with "failure to depart as expected" elevated to a negative discretionary factor that officers are instructed to weigh heavily. The agency has, in effect, removed the inside-the-U.S. alternative from the menu while simultaneously refusing to operate the consular bridge.

This creates several independent grounds for federal court review.

The class-action structure

The factual posture lends itself naturally to a Rule 23(b)(2) class because the relief sought is a single uniform injunction — adjudicate I-129F petitions on the merits, do not close them on the I-130-first basis — that operates identically across the class.

A working class definition: All U.S. citizen petitioners who have filed, or will file during the pendency of this action, Form I-129F seeking K-3 nonimmigrant status for their spouse under INA § 101(a)(15)(K)(ii), and whose I-129F petitions have been or will be administratively closed, held in abeyance, or otherwise denied final adjudicative disposition on the merits on the sole or principal basis that the corresponding Form I-130 petition was or will be approved before the I-129F.

The four Rule 23(a) requirements:

• Numerosity. The class is geographically dispersed across all 50 states and joinder of all members would be impracticable. The forward-looking component of the class — petitioners who will file during the pendency of the action — strengthens this analysis significantly, particularly if the litigation itself or related publicity prompts increased K-3 filings.
• Commonality. Every class member's claim turns on the same legal question: whether the agencies' uniform closure practice is lawful under the INA, the APA, and post-Loper Bright deference doctrine. Under Wal-Mart Stores v. Dukes, 564 U.S. 338 (2011), this is the kind of single, dispositive common question that satisfies commonality after the Court's narrowing of the doctrine.
• Typicality. Named plaintiffs whose I-129F petitions have been administratively closed under the standard NVC practice have claims typical of every other member of the class. The relief they seek — injunctive and declaratory — runs to every class member on identical terms.
• Adequacy. A satisfied requirement of competent counsel and named plaintiffs without conflicts.

Rule 23(b)(2) is the correct subsection because the relief sought is final injunctive and declaratory relief appropriate to the class as a whole. No individual monetary damages are sought. The relief is indivisible: an order requiring the agencies to adjudicate I-129F petitions on the merits and to forward approved petitions to consulates for K-3 issuance, regardless of I-130 status, benefits every class member in the same way at the same time.

The two hardest fights, addressed honestly

A page that pretends a novel class action is a slam-dunk does its readers no favors. There are two genuinely difficult arguments the government will press, and any serious treatment of this theory must engage with them.

The discretionary-action bar — INA § 242(a)(2)(B)(ii)

The Department of Justice will argue that closure decisions fall within agency discretion and are therefore unreviewable under INA § 242(a)(2)(B)(ii), which strips federal court jurisdiction over any "decision or action of the Attorney General or the Secretary of Homeland Security the authority for which is specified under this subchapter to be in the discretion of the Attorney General or the Secretary."

The response is that the closure practice is not a discretionary adjudicative decision under INA § 245 — it is a categorical refusal to adjudicate at all. The Supreme Court in Kucana v. Holder, 558 U.S. 233 (2010), narrowed § 242(a)(2)(B)(ii) to apply only where statutory text expressly commits discretion to the Secretary. The K-3 statute does not commit administrative closure of an I-129F to anyone's discretion; the practice is not authorized by statute at all. Norton v. SUWA further confirms that compelling discrete action the agency is required to take is not the same as reviewing how the agency exercises discretion.

A properly framed complaint asks the court to compel the discrete action of adjudication — not to dictate what that adjudication should conclude. That framing keeps the claim outside the jurisdictional bar. For deeper treatment of this issue, see our analysis at INA § 242 Discretionary Bar.

The "but they get the better visa" mootness argument

DOJ will argue closure is not a cognizable harm because the class members ultimately receive the IR-1 or CR-1 immigrant visa, which is superior to the K-3 (it confers LPR status on entry, with no separate I-485 needed). On this view, the K-3 is mooted because the better remedy is on the way.

The response is temporal, not qualitative. The K-3 was designed by Congress to bridge the separation period between I-130 filing and immigrant visa issuance. Telling a U.S. citizen petitioner that her IR-1 spouse will eventually arrive in 28 months does not answer the harm Congress legislated to prevent — it is the harm. The K-3 is not an alternative to the immigrant visa; it is a humanitarian supplement to the immigrant-visa wait. Treating K-3 as redundant with the immigrant visa is exactly the operational conflation that has rendered the statute a dead letter, and it is the conflation the litigation is designed to reach.

The standing analysis runs to the same point. The injury-in-fact is the separation period itself, not the eventual visa outcome. Lifting closure restores the bridge Congress built. The relief is concrete, particularized, and redressable by a court order to the defendant agencies.

Loper Bright and the deference question

Pre-Loper Bright, the agencies' closure practice would have received Chevron deference as a reasonable construction of an arguably ambiguous statute. That deference is gone.

Under Loper Bright Enterprises v. Raimondo, 144 S. Ct. 2244 (2024), federal courts must exercise independent judgment in determining the best reading of a statute. Agency interpretations may inform that judgment but do not control it. Where, as here, the agencies' construction of INA § 101(a)(15)(K)(ii) is unsupported by statutory text, contradicted by the statute's evident purpose, and contained only in internal operational guidance rather than notice-and-comment regulation, the deference owed is minimal at best — and zero in the appropriate frame. The court reads the statute itself.

The statute does not authorize closure on the I-130-first basis. The court should so hold. For a fuller doctrinal treatment of Loper Bright in the mandamus context, see Loper Bright and Mandamus.

Named-plaintiff criteria

The strength of any class action depends on the named plaintiffs. The ideal named-plaintiff profile in this case is narrow but achievable.

The strongest possible factual profile is a petitioner whose I-130 was approved within weeks of the I-129F filing, where the closure happened before the K-3 could ever have provided any benefit — making the categorical nature of the closure practice unmistakable on the record.

Even if class certification is denied, the case has value

An honest practitioner will acknowledge that novel class certifications are denied more often than they are granted, particularly in immigration cases where the government invokes the discretionary-action bar with some success. The right question is not "will we win class cert" — it is "is the case worth filing even if we don't."

The answer is yes, for several reasons.

Even an individual action forces the agencies to articulate, for the first time on the record, a defensible rationale for the closure practice. They have never had to do so. The Foreign Affairs Manual entry and informal USCIS practice were never published for notice-and-comment, never accompanied by a reasoned explanation, and never reconciled with the statutory text. Litigation will require the government to put a justification on paper that can be examined.

The case creates a public record that runs parallel to other PM-602-0199 challenges. As the legal community responds to the May 2026 memo across multiple fronts — adjustment denials, dual-intent challenges, the immediate-relatives exemption argument — a K-3 mandamus action contributes a discrete and powerful piece of the overall record that the memo's premises are unworkable.

Settlement, partial relief, or policy change becomes possible. Federal class actions are leverage even when they do not run to judgment. The agencies may prefer to quietly revise the closure practice, or carve out a category for cases where I-130 approval is imminent at I-129F filing, rather than litigate the question to a published opinion that constrains them more broadly.

For the named plaintiffs themselves, the case is also an individual mandamus. A class action that fails certification can be re-filed as an individual mandamus on the same facts — and individual K-3 mandamus actions are themselves novel, well-pleaded, and likely to attract favorable treatment in courts that have been receptive to delay-mandamus claims in other contexts.

What this page is, and what it is not

This page is a doctrinal analysis. It is not a settled litigation announcement, and it is not a guarantee that any particular case will be filed, certified, or won. The K-3 mandamus class action is a theory whose underlying conditions changed materially on May 21, 2026, and that change deserves careful evaluation by petitioners, by the immigration bar, and by anyone thinking about how to respond to PM-602-0199 with something more constructive than blanket denunciation.

If you are a U.S. citizen whose I-129F for a K-3 spouse has been administratively closed, and the structural posture described above matches your situation, the next step is a direct conversation. The criteria above are the screen. The case is the question.
