'He is delivering': Trump's first month flips script on radical Biden-Harris border policies

But it was just the latest in what has been a battery of overhauls to the U.S. immigration system.

Trump, who ran his campaign centered on border security and cracking down on illegal immigration, got to work on day one of his administration - signing executive orders that declared a national emergency at the border and deployed the U.S. military. He also signed orders ending birthright citizenship for children of illegal immigrants, suspending refugee admissions and also ending the use of the CBP One app at the southern border to admit migrants via humanitarian parole.

Other orders included moves to restart border wall construction, which had ended under the Biden administration.

It wouldn't take long before the moves were followed up by additional decisions from Cabinet agencies. The Pentagon quickly deployed troops to the southern border and also opened up Guantánamo Bay to flights of migrants.

DHS has also gone after federal funding to migrant causes. Most recently, four Federal Emergency Management Agency (FEMA) employees were fired and tens of millions of dollars taken back from New York City designated for hotels where migrants are being housed.

"Secretary [Kristi] Noem has clawed back the full payment that FEMA deep state activists unilaterally gave to NYC migrant hotels," a DHS spokesperson told Fox News Digital. 

Meanwhile, the administration quickly moved to ramp up interior arrests and deportations. A number of high-profile raids were quickly launched across the U.S., particularly in "sanctuary" cities that do not cooperate with ICE agents. Daily arrests quickly moved above 1,000 a day, and officials pointed to a number of criminals and gang members that were picked up in the process.

According to DHS data, obtained by Fox News Digital, there were 11,791 interior ICE arrests from Jan. 20 to Feb. 8, compared to 4,969 during the same period in 2024. That's a 137% increase.

Arrests of aliens with criminal histories have soared by nearly 100% from 4,526 in the same period in 2024 to 8,993 under Trump this year. Arrests of fugitive aliens at-large, meanwhile, have gone up from 2,164 to 5,538, a 156% increase. Arrests of criminal aliens in local jails have risen 59%.

The new Trump era has seen the rapid unwinding of a number of Biden-era programs. Fox News Digital confirmed on Wednesday that DHS has now paused pending applications for three Biden-era programs: Uniting for Ukraine; parole processes for Cuba, Haiti, Nicaragua and Venezuela (CHNV); and family reunification programs.

Trump had already ordered an end to the use of some Biden-era parole programs on day one, including CHNV. He had also ordered the end to the practice of paroling migrants at ports of entry who had made appointments on the CBP One app. 

Migration strategies often require foreign cooperation, and the Trump administration used diplomacy and tariff threats to secure additional cooperation with neighbors and other countries in the region. 

Both Canada and Mexico agreed to ramp up their border security efforts after Trump floated new tariffs on incoming goods from their countries. Meanwhile, both Venezuela and Colombia agreed to take back their immigrants being deported, with Colombia's president backing down after a public clash with President Trump. 

Guatemala, separately, agreed to accept deportees from other countries as part of a deal hashed out with Secretary of State Marco Rubio.

So far, there are indications that border numbers continue to trend lower with the new administration. 

Meanwhile, border czar Tom Homan said this week that Border Patrol "has encountered a total of 229 aliens across the entire southwest border" in a single day and rallied around President Trump, saying, "He is delivering."

"That is down from a high of over 11,000 a day under Biden," he said. "I started as a Border Patrol Agent in 1984, and I don't remember the numbers ever being that low."
