Fact check: Can ICE arrest a legal permanent resident without a warrant?

1. Summary of the results

Based on the analyses provided, ICE can arrest a legal permanent resident without a warrant under specific circumstances. The evidence shows multiple documented cases where this has occurred:

• Victor Avila, a green card holder, was detained by ICE at San Francisco International Airport after returning from visiting his son in Japan, demonstrating that ICE can detain legal permanent residents without warrants at ports of entry ^[1]
• Mahmoud Khalil was arrested by ICE without a warrant under what government lawyers claimed were "exigent circumstances," where officers believed he would escape before they could obtain a warrant ^[2]
• A Marine Corps veteran's wife was detained during a routine green card appointment, showing ICE can arrest legal permanent residents even during official immigration proceedings ^[3]
• Legal permanent residents with criminal records are being arrested by ICE upon reentering the country, indicating that prior criminal history can justify warrantless arrests ^[4]

While sources indicate that officers must have a judicial warrant signed by a judge to enter a home ^[5], this requirement appears to apply specifically to home entries rather than arrests in other locations.

2. Missing context/alternative viewpoints

The analyses reveal several important contextual factors not addressed in the original question:

• Location matters significantly - ICE appears to have broader authority to detain individuals at airports, ports of entry, and during official immigration appointments without warrants compared to home arrests ^{[1] [3]}
• Criminal history as a factor - Legal permanent residents with criminal records face heightened risk of warrantless detention, particularly when reentering the country ^[4]
• "Exigent circumstances" exception - ICE can justify warrantless arrests when they claim reasonable belief that the individual might flee ^[2]
• Current enforcement climate - The Trump administration's immigration crackdown has intensified these practices, affecting even legal permanent residents ^[1]
• Rights awareness gap - Multiple sources emphasize the importance of understanding one's rights during ICE encounters, suggesting many legal permanent residents may not know their protections ^{[5] [6]}

3. Potential misinformation/bias in the original statement

The original question itself does not contain misinformation, as it poses a legitimate legal inquiry. However, the question's framing could lead to incomplete understanding:

• The question implies a binary yes/no answer when the reality is more nuanced - ICE's authority varies significantly based on location, circumstances, and the individual's background
• The question doesn't acknowledge the distinction between different types of arrests - home entries require warrants while detentions at airports or during official appointments may not ^{[5] [1]}
• There's no recognition of practical enforcement patterns - while legal protections may exist on paper, the documented cases show ICE regularly detains legal permanent residents without warrants in various circumstances ^{[2] [1] [3] [4]}

The question would benefit from more specific framing about circumstances, locations, and the practical versus theoretical aspects of ICE's enforcement authority.
