Key Takeaways
• Hundreds charged with national security crimes after entering National Defense Areas at the southern border since April 2025.
• Military control now governs nearly 110,000 acres across three border states under the National Security Presidential Memorandum NSPM-4.
• Legal challenges question constitutionality, citing the Posse Comitatus Act and new, harsher penalties of up to 18 months jail time.
A new militarized border zone along the southern United States 🇺🇸 border has led to hundreds of immigrants being charged with national security crimes since late April 2025. This marks a major change in immigration law enforcement. New rules, stronger penalties, and military involvement have caused debate about constitutional rights, legal limits, and treatment of those trying to cross the border. Here, we break down what’s happening, why it matters, and what could come next.
The Start of the Militarized Border Zone
On April 11, 2025, President Trump signed the National Security Presidential Memorandum (NSPM-4). This order shifted large areas of federal land along the southern border from the Department of the Interior to the Department of Defense. This action formally made these areas military-controlled zones.
These areas, now labeled as National Defense Areas, put parts of the border under direct military control. The stated goal, according to the memorandum, was to “seal the southern border” and to “repel invasions.” Simply put, the administration argued this move was needed to protect national security.
Size and Location of the Military Zone
The militarized zone is a 60-foot-wide federal strip reaching across three border states. Here’s how it’s laid out:
- In New Mexico, there’s a new military zone that runs about 170 miles.
- In western Texas, the National Defense Area stretches about 60 miles from El Paso to Fort Hancock.
- Oversight of these areas falls to U.S. Army commands based at Fort Bliss in Texas and Fort Huachuca in Arizona.
In total, this change moved almost 110,000 acres of federal land from the Department of the Interior to the Pentagon. The transfer is expected to last for three years.
This move means that rather than being just under regular border control (like Customs and Border Protection patrols), these pieces of land now have military status. The Defense Department has authority—at least for the next three years.
New Charges and How They Work
Since the military took over these border strips in April, immigration enforcement in these areas has become much tougher. Several hundred immigrants have faced criminal charges for entering these restricted zones.
What Are Immigrants Being Charged With?
Charges filed include:
- Violating security rules by entering the National Defense Areas.
- Misdemeanor and petty misdemeanor crimes for being on military property without permission.
For anyone caught, these new national security charges are much harsher than the usual criminal penalty for entering the United States 🇺🇸 without documents.
Here’s what’s at stake:
- Up to 18 months in jail for the national security crime.
- An extra possible six months in jail for illegal entry.
- Fines of up to $100,000 per person.
According to documents from federal court, about 400 cases had already been filed in the Las Cruces federal court by May 13, 2025. The first group prosecuted included 28 migrants who crossed into the military zone in New Mexico at the end of April.
Why the Change? The Government’s Point of View
The Trump administration argues that creating these National Defense Areas and making the border more of a militarized zone is needed to protect the United States 🇺🇸. Officials say they are following the law, acting under the National Security Presidential Memorandum, and using powers from a national emergency declared on January 20, 2025.
Despite claims by some government leaders that border crossings have gone down, they insist the military’s job is “to seal the border” and to “repel invasions.” Putting the land under the Pentagon’s direct control, they say, allows for a stronger response to threats and, in their view, meets the country’s security needs.
The Legal Fight
Not everyone agrees with these new steps. Many lawyers, public defenders, and constitutional experts are raising serious questions about whether this military approach is legal or even allowed by the U.S. Constitution.
What Are the Legal Challenges?
The federal public defender’s office in Las Cruces is trying to get the recent charges thrown out of court. They are arguing that:
- The government must prove that immigrants knew they were entering a military zone.
- Immigrants must have crossed “in defiance” of the rule, meaning they must have purposely ignored the law or acted with some bad purpose.
A federal judge, Gregory Wormuth, has asked for more information from both sides. He says this is an “unprecedented” situation—meaning it’s never really been done before.
On the other side, U.S. Attorney Ryan Ellison says that there are hundreds of clear “restricted area” signs, written in both Spanish and English, posted along the New Mexico part of the border.
Big Legal and Constitutional Issues
Many legal scholars and immigrant advocates worry that:
- Using the military this way might break the Posse Comitatus Act. This law stops the army from acting as regular law enforcement inside the United States 🇺🇸.
- Transferring so much federal land to the military might break a rule that says Congress must approve any Pentagon takeover of over 5,000 acres, except during wars or declared national emergencies.
- The administration is depending on a national emergency, even though they also claim illegal crossings are down.
Officials say they have not used the older, more well-known Insurrection Act of 1807, which allows the president to use the military in cases of rebellion or civil unrest. By not officially using this law, some argue the administration is trying to avoid deeper legal or political controversy.
What’s Actually Happening at the Border?
Despite the tough talk about “invasions” and the heavy presence of troops, official numbers tell a different story. Border arrests have dropped steeply, reaching their lowest levels since the mid-1960s. Government data from March 2025 shows that monthly unauthorized crossings have dropped about 95%.
Even with these record-low crossings, the government sent thousands of troops to the border. Customs and Border Protection continues to make most of the arrests, even though they now have the option to let U.S. military troops help detain migrants.
As of now, there have been no reports of military personnel actually arresting immigrants. Enforcement is technically still led by civilian agencies.
Critics’ View
Opponents of the policy see it as an attack on legal rights and a threat to basic freedoms. Some argue that:
- Civil liberties may be at risk if the military acts outside its normal limits in dealing with people crossing the border.
- Having the military run what amounts to civilian law enforcement could create confusion and lead to more aggressive responses.
- There’s a risk that people who do not understand the system, or who do not see the border signs, could be treated much more harshly than they would have been under previous rules.
Court filings and analysis from many groups note that most immigrants facing these new criminal charges are first-time border crossers. Before NSPM-4 and the militarized zone, they would have likely been processed and returned quickly—with only a warning or, at most, a light penalty. Now, with these new national security charges, many face long jail sentences and huge fines.
What Happens Next?
Legal experts expect that this issue is not going away. The federal courts will need to decide if President Trump’s National Security Presidential Memorandum oversteps important laws about military power and land transfers. Lawsuits or appeals could reach the higher federal courts or even the Supreme Court.
If judges decide the administration went too far, some or all charges against immigrants could be dropped or reduced. If the courts let these rules stay, it could mean this kind of military control over immigration enforcement becomes normal.
Who Is Affected?
The new rules affect more than just the people crossing the border illegally. Here are the main groups affected:
- Immigrants: Especially those who may not know about the military zone and tougher laws.
- Border-area communities: Local people may see more military activity and changes in the way the land is used.
- Advocates and lawyers: Defenders working with immigrants have more complicated cases to handle and new legal questions to answer.
- Taxpayers: Costs for running a militarized border—both in money and resources—may increase as military operations grow.
The Role of National Defense Areas in Immigration
By using National Defense Areas, the government has turned border sections into military territory. Normally, areas like this are used for protecting things like nuclear plants or military bases. Using this label for parts of the border is new.
Now, crossing these areas carries the risk of punishment that is harsher than normal, even for someone who just sets foot across the line. Many say this could discourage people from seeking safety or a better life but also increases the burden on already busy federal courts.
VisaVerge.com’s investigation reveals that these moves have raised fresh questions about how much the government can use military tools for immigration. Policies like these could change the future of border security, immigration courts, and the way rights are protected at the border.
Border Security or Overreach?
The big question remains: Does sealing the border with military force make the country safer, or does it cross a line into unfair treatment and possible violations of law? Supporters argue the strict stance is needed for national security, while critics see a shift toward treatment of immigrants as criminals rather than people seeking help.
As with many big policy changes, it will likely take months or even years of court cases and public debate to find out where the line will be drawn.
What Can You Do?
If you are worried about changes to the border, face charges, or want reliable details about border policies, it’s always best to consult official government resources or a licensed immigration attorney. To learn more about border security, legal rights, and how the government sets up military zones, you can visit the U.S. Department of Homeland Security’s official page.
In the coming months, as courtrooms and policymakers weigh legal, moral, and practical issues around the militarized zone, expect more updates and possible changes. People affected should stay informed and, if needed, get legal advice about how these policies might apply to them and their families.
Summary
In summary, the new militarized border zone, created through President Trump’s National Security Presidential Memorandum, adds stiffer penalties and shifts control of large parts of the border to the military. This move, now enforced in the form of National Defense Areas, has led to hundreds of immigrants facing new national security charges. The result is a fierce debate about the right balance between national security and individual rights, with courts and policy makers likely settling many of these matters in the near future. The full impacts for immigrants, local communities, and the country as a whole are yet to be seen, but what is clear is that U.S. border enforcement has entered a new era.
