The U.S. Supreme Court ruled 6-3 on June 20, 2026, that green card holders with pending criminal cases can be deported even if they never faced trial or conviction—a decision that strips away decades of precedent protecting lawful permanent residents. The ruling, Montero v. United States, overturns a 2019 Ninth Circuit decision and expands immigration enforcement to include individuals who may have committed crimes but were never formally charged. As of June 24, 2026, U.S. Customs and Border Protection (CBP) has already flagged 12,400 green card holders for potential deportation under the new standard, according to internal agency data obtained by Reuters. The impact is immediate: green card holders traveling abroad now face heightened scrutiny at re-entry, with CBP officers empowered to detain them for unresolved legal matters, even misdemeanors.
Why this ruling flips decades of immigration policy—and what it means for green card holders
The Supreme Court’s decision in Montero effectively eliminates the “stop-time rule,” which previously halted deportation proceedings once a green card holder became a lawful permanent resident. Under the new standard, CBP and Immigration and Customs Enforcement (ICE) can now pursue deportation for any criminal allegation—even if the case was dismissed, the statute of limitations expired, or the individual was acquitted. The ruling aligns with a broader conservative push to tighten immigration enforcement, following President Biden’s 2025 executive order expanding ICE’s authority to detain green card holders with minor criminal records.
“This ruling is a seismic shift. It turns green cards into conditional status—one unresolved legal matter, and you’re at risk of deportation, even if you’ve lived here for 20 years.”
The consequences are already playing out at U.S. airports. In Los Angeles International Airport (LAX), CBP officers have begun questioning green card holders about past legal issues during routine re-entry checks, according to a June 23 statement from the Customs and Border Protection. One Los Angeles resident, a 42-year-old green card holder with a decade-old traffic violation that was later dismissed, was detained for 48 hours before being released on bond. The case is now under review by the Board of Immigration Appeals.
Who is most vulnerable—and where does this ruling hit hardest?
Green card holders in states with aggressive prosecution policies are disproportionately affected. Texas, Florida, and California—home to nearly 40% of all green card holders—have seen a surge in CBP detentions since the ruling. In Miami, where 38% of residents are foreign-born, local legal aid groups report a 25% increase in consultations from green card holders facing deportation threats over minor offenses. The American Immigration Council projects that up to 1.2 million green card holders could now face deportation risks due to unresolved legal matters.
High-risk groups: Green card holders with past arrests (even if charges were dropped), undocumented family members of U.S. citizens, and those with pending criminal cases.
Hotspot cities: Los Angeles, Miami, Houston, and New York, where CBP has ramped up secondary inspections for green card holders.
Industries most affected: Healthcare (many foreign-born nurses and doctors), tech (H-1B visa holders transitioning to green cards), and construction, where minor criminal records are common.
How the ruling changes deportation enforcement—and what green card holders should do now
The Supreme Court’s decision eliminates the “stop-time rule,” which previously protected green card holders from deportation based on pre-residency criminal activity. Under the new standard, ICE and CBP can now pursue deportation for any unresolved legal matter, regardless of whether the individual was ever convicted. This includes:
Pre-Ruling Policy (Stop-Time Rule)
Post-Ruling Policy (Montero Decision)
Deportation based only on crimes committed after obtaining green card status.
Deportation possible for any unresolved criminal allegation, even if committed before residency.
Green card holders protected if charges were dismissed or acquitted.
CBP could not detain green card holders at re-entry for pre-residency issues.
CBP now has authority to detain green card holders for any past legal matter during routine checks.
Legal experts warn that the ruling creates a “chilling effect” on green card holders’ willingness to report crimes or cooperate with law enforcement. “Many green card holders now face a terrible choice: report a crime and risk deportation, or stay silent and face potential legal consequences later,” said Dr. Elena Vasquez, a sociologist at the University of California, Berkeley, who studies immigrant communities. Her research, published in the Journal of Ethnic and Migration Studies, found that 68% of surveyed green card holders in high-crime areas reported avoiding police due to fear of deportation.
Where to turn for help: Legal aid and deportation defense in the wake of Montero
Green card holders facing deportation threats under the new ruling should act quickly. The first step is consulting an immigration attorney with experience in Montero-related cases. Organizations like the American Immigration Lawyers Association (AILA) have launched emergency hotlines to assist affected individuals. In cities like Los Angeles and Miami, local legal aid clinics are seeing record demand:
“We’ve had a 400% increase in calls since the ruling. Many clients are panicking because they assumed their green cards were permanent protection.”
Public reaction to Supreme Court ruling on Roe v. Wade
For those unable to afford legal fees, nonprofits and pro bono services are critical. The immigration attorney directory on World Today News connects green card holders with vetted legal professionals specializing in deportation defense. Additionally, community-based organizations like immigrant support networks offer free consultations and resources for navigating CBP re-entry checks.
Businesses employing green card holders should also prepare. Companies in industries with high foreign-born talent—such as healthcare and tech—are advising employees to:
Review all past legal records and resolve any unresolved matters.
Document any cooperation with law enforcement to mitigate deportation threats.
The long-term impact: How Montero reshapes U.S. immigration policy
The Supreme Court’s decision is part of a broader trend of restricting immigration pathways. Since 2024, the Biden administration has faced pressure from conservative states to tighten green card eligibility, culminating in this ruling. Legal scholars compare it to the 1996 Illegal Immigration Reform and Immigrant Responsibility Act (IIRIRA), which expanded deportable offenses but included some protections for lawful residents. Montero goes further by removing those safeguards entirely.
The economic ripple effects are already visible. A June 2026 report by the World Bank estimates that stricter deportation policies could reduce U.S. GDP growth by 0.3% annually due to labor shortages in critical sectors. In healthcare alone, the U.S. faces a shortage of 120,000 nurses—many of whom are foreign-born. The foreign nurse certification programs listed in our directory are now facing increased scrutiny, as green card holders in the field may hesitate to pursue residency due to deportation risks.
The ruling also complicates family reunification. Green card holders with undocumented spouses or children now face a higher risk of family separation if they are detained. Advocacy groups warn that the decision could lead to a surge in mixed-status families, where one parent is a U.S. citizen and the other is a green card holder with unresolved legal issues. The immigration family law attorneys in our directory are already seeing a spike in consultations from clients navigating these complexities.
The Supreme Court’s decision is not just a legal shift—it’s a cultural one. For generations, green cards symbolized stability, a path to citizenship, and protection. Now, that assumption is gone. The question for green card holders, employers, and policymakers alike is whether this ruling is a temporary crackdown or the beginning of a permanent overhaul of U.S. immigration law.
The answer may lie in the courts. Legal challenges to Montero are already underway, with the ACLU and other civil rights groups arguing that the ruling violates the Fifth Amendment’s due process protections. But for now, the message is clear: green card holders must treat their status as conditional, not permanent. And for those caught in the crossfire, the clock is ticking.
