In 2026 alone, federal courts blocked the rule ending Duration of status (D/S)The period of stay for F, J and I nonimmigrants, who are admitted for as long as they maintain their program or activity rather than until a fixed date. It appears as D/S on Form I-94.See it in the glossary for students, set aside a State Department suspension of Immigrant visaA visa issued at a consulate to a person intending to live permanently in the United States. On admission the holder becomes a permanent resident.See it in the glossary for 75 countries, and struck down the Executive orderA directive from the President to federal agencies and officials about how to run the executive branch and carry out the law. Executive orders are numbered and published in the Federal Register, and they generally bind the executive branch.See it in the glossary on birthright citizenship. Courts also upheld government positions, including suspicionless phone searches at the border. The pattern can look political. Most of these decisions, however, turn on a small set of legal questions that apply regardless of who is in office.
This guide explains those questions in plain language.
Question 1: Did the agency have authority?
Agencies can do only what Congress has authorized. A court asks whether the statute actually grants the power the agency claims. Examples:
- On August 21, 2026 a federal court vacated the State Department’s 75-country immigrant visa suspension, holding that it exceeded the Secretary of State’s statutory authority, as we reported.
- A court vacated guidance implementing the original $100,000 Cap-subject and cap-exempt (H-1B)The H-1B category has an annual limit of 65,000 new visas or statuses per fiscal year, plus 20,000 more for people with a U.S. master's degree or higher. Petitions counted toward that limit are cap-subject. Petitions from higher education institutions, their related or affiliated nonprofits, and nonprofit or governmental research organizations are cap-exempt.See it in the glossary payment, holding that it functioned as a tax the executive lacked power to impose, covered in our fee status article.
Since the Supreme Court’s decision in Loper Bright Enterprises v. Raimondo in 2024, courts decide for themselves the best reading of an ambiguous statute instead of deferring to a reasonable agency interpretation. That shift gives judges more room to reject agency readings of immigration law.
Question 2: Did the agency follow the required procedure?
The Administrative Procedure Act generally requires agencies to publish proposed rules, accept comments and respond to significant ones before adopting binding regulations. A rule adopted without those steps, or a binding policy disguised as guidance, can be set aside. Interim final ruleA rule that takes effect without a prior comment period. The agency accepts public comments after it is published and may revise the rule afterward.See it in the glossary that skip prior comment are frequent targets, because agencies must show “good cause” for skipping it.
Question 3: Was the decision reasoned?
Under 5 U.S.C. 706, courts set aside actions that are “arbitrary and capricious.” In practice, a court asks whether the agency considered the important aspects of the problem, weighed reasonable alternatives, responded to significant comments and explained how the rule serves its goals.
The duration of status case is a clear example. In postponing the rule on September 14, 2026, the judge found DHS likely failed to analyze costs and benefits adequately, consider less burdensome alternatives, respond to significant comments and explain how fixed admission periods would advance its fraud and security goals, according to AIP’s report. The Supreme Court used the same kind of analysis in DHS v. Regents in 2020, holding that ending Deferred Action for Childhood Arrivals (DACA)A policy begun in 2012 under which certain people who came to the United States as children could request deferred action, a discretionary decision not to pursue removal for a set period, along with work authorization. Deferred action does not provide lawful status. Under current court orders, USCIS continues to process renewals but is not approving initial requests.See it in the glossary without adequate explanation was unlawful.
Question 4: Does it violate the Constitution?
Constitutional challenges are less common but can be decisive. On June 30, 2026, the Supreme Court held in Trump v. Barbara that the executive order limiting birthright citizenship violated the Fourteenth Amendment. Due process claims arise in detention cases, such as the Ninth Circuit’s ruling on Bond hearingA hearing in which an immigration judge decides whether a noncitizen detained by DHS may be released from custody and, if so, under what bond. Eligibility depends on which detention law applies to the person, and immigration judges have no authority over bond for some groups, such as those subject to mandatory detention.See it in the glossary for AsylumProtection granted to a person already in the United States or at a port of entry who meets the definition of a refugee and cannot safely return to their country.See it in the glossary seekers, covered here.
Why so many cases in immigration
- Rapid policy change. Many actions are taken quickly, with short or skipped comment periods, which invites procedural challenges.
- Organized challengers. Universities, states, employers, unions and advocacy groups have standing and resources to sue.
- High stakes. Rules affect large numbers of people, so the harm needed for a preliminary injunction is often easy to show.
- A dense statute. The Immigration and Nationality Act is detailed, so there is often a specific provision a policy can conflict with.
Courts also rule for the government
Blocked rules get more attention than upheld ones. The Supreme Court upheld a broad entry restriction in Trump v. Hawaii. In 2025, it limited universal injunctions in Trump v. CASA. In September 2026, an appeals court allowed suspicionless cellphone searches at the border, as we reported. Courts frequently give the executive broad room on national security and entry decisions.
What a ruling decides, and what it does not
- A preliminary injunction or stay is a prediction that the challengers will likely win, not a final decision.
- Vacatur sets a rule aside, but the agency can often try again with a better process or explanation.
- A ruling on procedure does not decide whether the policy itself is wise or even whether a different version could be lawful.
- An appeal can pause or reverse a ruling, sometimes within weeks.
What this means for an individual
A court order changes what agencies can do, and agencies usually post notices explaining how they will comply. The duration of status order, for example, led USCIS to keep accepting older form editions, as we reported. The safest approach is to follow official agency instructions issued after a ruling, rather than headlines, and to recheck before any filing or trip. For the difference between these orders, see our glossary of legal terms.
How to follow a case that affects you
- Find the case name and number in agency notices or news coverage that links to court records.
- Note what kind of order was issued and who it covers.
- Watch for an appeal and any request for a stay, which can change the practical result quickly.
- Rely on the agency’s posted compliance instructions for filing decisions.
Common questions
If a court blocks a rule, can the agency issue it again?
Often yes. If a rule was set aside for procedural reasons or inadequate explanation, the agency can try again with a new process. If the court held the agency lacked authority, the agency may need Congress to act.
Why do some cases get decided in days and others take years?
Emergency requests for temporary relief are decided quickly. Final decisions, appeals and Supreme Court review take much longer. A policy’s status can change several times while a case is pending.
Do court rulings protect only the people who sued?
It depends on the remedy. After Trump v. CASA, injunctions generally protect parties, but class actions and orders setting aside rules under the Administrative Procedure Act can reach much more broadly.
Is the Loper Bright decision specific to immigration?
No. It applies to all federal agencies. It matters in immigration because many rules depend on how agencies read statutes, and courts now decide those questions without deferring to the agency.
