Fewer than 600 illegal crossings were recorded at the southern border Sunday — a dramatic plummet from the thousands regularly encountered at the height of the Biden administration’s border crisis.

Across the entire southern border, just 582 people were caught attempting illegal crossings, with not one of the nine sectors from Texas to California seeing more than 200 people, according to Fox News.

In Texas’ Del Rio sector — which regularly saw 4,000 daily crossings when the crisis peaked in December 2023 — just 60 people were caught on Sunday.

The numbers are a startling drop from the peaks of the border crisis when more than 6,000 people were sometimes encountered across the southern border.

Even in the final days of the Biden administration, daily encounters were around 1,400.

The drop-off began almost as soon as President Trump took office on Jan. 20 and vowed to begin a crackdown on the border.

Encounters dropped day-by-day in the first three days of the new administration, with 1,073, 736, and 714 recorded January 20 through 22, Fox News reported.

During his inauguration speech, Trump revealed that he would “declare a national emergency at our southern border” and “repel the disastrous invasion of our country” by sending soldiers to the border.

“We will begin the process of returning millions and millions of criminal aliens back to the places from which they came,” he said.

And he quickly followed through on those promises — so far 1,500 troops from the US Army have been sent down south, while the president has been mulling deploying up to 10,000 total.

Immigration and Customs Enforcement has also begun conducting raids in sanctuary cities.

More than 7,300 illegal immigrants were arrested across the country in the first week of the raids, with 1,179 being detained on Sunday alone.

Trump’s newly appointed border czar, Tom Homan, declared “our border is closed” and vowed to continue deportations daily until millions of illegal immigrants are expelled from the country.

“You’re going to see the numbers steadily increase, the number of arrests nationwide,” Homan told ABC News on Sunday.

“Right now, it’s concentrating on public safety threats [and] national security threats. That’s a smaller population.

“So we’re going to do this on a priority [basis], that’s President Trump’s promise. But as that aperture opens, there’ll be more arrests nationwide,” he said, adding that the objective is to deport “as many as we can get.”

“If you’re in the country illegally, you’re on the table because it’s not OK to, you know, violate the laws of this country,” Homan said.
