Donald Trump promised to secure the border and deport criminals. By mid-2026 he had done that, and far more: cut refugee admissions to the lowest level on record, stripped legal status from over a million people, made a green card slower to get than at almost any time in history, and presided over the first year of negative net migration in roughly half a century. This is a tour of what was promised, what was done, what it costs, and why the case for it rests on claims the evidence does not support.
Immigration runs hot, so this page is built to be checked, not to shout. Each load-bearing claim is tagged by how solid it is:
Documented a policy action or official number on the record. Strong evidence a robust research finding or consensus. Mixed a genuine tradeoff where the honest answer has two sides. Contested experts disagree or it is unsettled.
The myths section gives each claim its strongest version and its kernel of truth before weighing it against the evidence, because a debunk that ignores what is real about a fear does not persuade anyone who holds it. Where immigration carries genuine costs, this page says so plainly.
Almost every immigration argument collapses two different things, so it is worth being precise before anything else. The roughly 52 million foreign-born people in the United States are not a single group, and most are not here illegally.
That last point is the hinge of this whole story. When the administration terminated Temporary Protected Status and parole programs, it did not, by itself, deport anyone. It converted more than a million people who were here legally into "illegal" immigrants, with the stroke of a pen. The line between legal and illegal is not only something migrants cross. It is something the government draws, and redraws. Documented
Both slogans flatten the same reality. "They're all illegal" is false, since most immigrants are here lawfully. And "just come legally" assumes a line that, for most people, does not exist (Part 2 returns to this). The honest picture is a set of narrow, capped, and shifting categories, in which legal and illegal are less a moral binary than a status that policy can grant or strip. This page keeps the two distinct, and flags which one each claim is actually about, because most of the crackdown described next fell on the legal side.
The campaign was about the border and about criminals: stop the crossings, deport the dangerous. By one measure, the border part worked. Southwest border encounters fell from about 1.53 million in fiscal 2024 to about 238,000 in fiscal 2025, the lowest in any year since 1970. (Pew Research, CBP) Documented
But the program reached far past illegal immigration. The same administration moved, piece by piece, against the legal system: refugees, asylum seekers, temporary-status holders, work-visa holders, green-card applicants, and even birthright citizenship. Here is the record by mid-2026.
The throughline: this was not only about people crossing illegally. It was a broad contraction of legal immigration and a challenge to citizenship by birth. The clearest single proof is the bottom line below.
Enforcement became the centerpiece. The 2025 budget law poured roughly $170 billion into immigration enforcement, including about $45 billion for new detention, making ICE the highest-funded federal law enforcement agency in the country. The detention population roughly doubled in a year to a record of about 70,000 by January 2026. (American Immigration Council; TRAC) Documented
The promise was "the worst first," violent criminals. The data show something else. By late 2025, about 74 percent of people in ICE detention had no criminal conviction, and only about 5 percent had a violent one. Nearly all of the growth in detention came from people with no criminal record at all. (TRAC Syracuse; Cato Institute) Documented
DHS counters that 70 percent of arrests are of people "convicted or charged" with crimes, but that figure folds in people merely accused and routine immigration violators. Both can be partly true: some of those removed are genuine, serious offenders, and DHS publicizes them. But the conviction-based numbers are clear that the net widened far beyond the "worst of the worst." The Laken Riley Act, the first law Trump signed in 2025, made detention mandatory for people merely charged with minor offenses like shoplifting. Mixed
The dragnet reaches into ordinary life. ICE ran sweeps at Home Depot parking lots, car washes, and worksites, and made arrests at courthouses and at immigrants' own check-in appointments. The administration rescinded the longstanding policy keeping agents away from schools, churches, and hospitals. It expanded agreements deputizing local police to more than 1,000 agencies. And it moved to feed ICE data the government had never used for enforcement, including IRS tax records and Medicaid enrollment files. (DHS; ACLU; KFF; courts have blocked parts of the data-sharing) Documented
There is a bitter irony in the tax piece. Undocumented immigrants paid an estimated $97 billion in taxes in 2022, much of it filed voluntarily through IRS-issued taxpayer numbers. The administration then sought to hand that very tax data to ICE to locate them. The compliance the system invited became the map for the raids.
Often to their home countries. But increasingly to third countries that are not theirs at all. In March 2025, the US flew about 238 Venezuelan men to El Salvador's CECOT mega-prison, most under the Alien Enemies Act of 1798, a wartime law invoked in peacetime, and paid El Salvador several million dollars to jail them. They got no hearings and were held incommunicado for about 125 days before being released in a prisoner swap; several later described beatings and abuse. Alleged gang membership was often determined by tattoos and clothing that gang experts say are not reliable markers. The US also sent men to South Sudan and to Eswatini, countries to which most had no connection. (Supreme Court filings; Reuters; CNN; NPR) Documented
Courts pushed back. The Supreme Court held that even under the Alien Enemies Act, people are entitled to notice and a chance to challenge removal, and a federal judge later found the CECOT removals violated due process and ordered the government to facilitate returns. Documented
This is not only about recent arrivals. A California couple was deported after 35 years in the country with no criminal record, leaving behind three US-citizen daughters. US-citizen children, including a four-year-old undergoing cancer treatment, were removed alongside their deported parents (DHS disputes the framing, saying citizen children left with parents by choice). The administration also detained green-card and student-visa holders over political speech, including Columbia's Mahmoud Khalil (a lawful permanent resident) and Tufts' Rumeysa Ozturk, both ordered released by judges citing the First Amendment. Documented
The starkest case: Kilmar Abrego Garcia, a Maryland man with a court order barring his deportation to El Salvador, was sent to CECOT anyway in what the Justice Department admitted was an "administrative error." The Supreme Court ordered the government to facilitate his return. A nationwide expansion of "expedited removal" now lets the government deport people in days, without a hearing, unless they can prove they have been in the country for more than two years. And 2025 was the deadliest year in ICE custody in about two decades. (Supreme Court; TRAC; NPR) Documented
An honest measure of scale: despite the record detention and spending, actual removals ran only about 7 percent above the previous year (TRAC). The visible change is less a historic surge in deportations than a much wider net, falling heavily on people who committed no crime, including some who were here legally.
Immigration is woven into the parts of the economy most Americans rely on without seeing. Pull the thread and things unravel in predictable ways.
Roughly half or more of hired crop farmworkers are foreign-born. About 27 percent of direct-care workers (the people who care for the elderly and disabled) are immigrants, and 42 percent of home health aides are foreign-born. Construction is about 23 percent foreign-born. (USDA; PHI 2024; American Immigration Council) Documented
When that labor is removed, the result is not a wave of natives filling the jobs. Studies of past enforcement (the Secure Communities program) found that crackdowns reduced the employment and wages of U.S.-born workers too, because immigrant and native labor are often complements, not substitutes. Modeling of mass deportation projects higher consumer prices, on the order of 1.5 percent to 9 percent by 2028 depending on scale, in food, housing, and care. (Journal of Labor Economics; Peterson Institute) Strong evidence magnitude uncertain
The nonpartisan Congressional Budget Office estimated that the 2021-2026 immigration surge would raise GDP by about $8.9 trillion over a decade and reduce federal deficits by roughly $0.9 trillion, because immigrants work, spend, and pay taxes. Run that in reverse and restriction shrinks the workforce and slows growth. (CBO, July 2024) Strong evidence
The country is getting older and the ratio of workers to retirees is falling. Immigration is the main thing slowing that decline; it modestly improves Social Security's long-run balance and adds prime-age workers. Cutting it accelerates the squeeze on the programs older Americans depend on. (Penn Wharton Budget Model; SSA Trustees) Strong evidence a tailwind, not a cure
The crackdown also made the legal path, the one critics tell people to use, harder. For most people who want to immigrate, there is no line to get into. One analysis estimates that over 99 percent of people who want to immigrate legally have no eligible category at all. For those who do, the waits are measured in decades. (Cato Institute; American Immigration Council) Documented
Leaving the country to "do it the right way" can itself trigger a 3- or 10-year bar on returning, a catch-22 that traps people who would gladly use a legal route. (American Immigration Council) Documented
The crackdown and the claims behind it trace to the president's own words. For a decade, Donald Trump has described immigrants in sweeping and dehumanizing terms. Quoting him is not editorializing; it is the record. And nearly every checkable claim in that rhetoric has been examined by news organizations and found false.
It started at the beginning. Announcing his first campaign on June 16, 2015, he said of Mexican immigrants:
"They're bringing drugs. They're bringing crime. They're rapists. And some, I assume, are good people."
Campaign announcement, June 16, 2015 (Time, full transcript)
The signature recurring claim is that other countries deliberately empty their institutions into the United States. He has said it at the Republican National Convention in July 2024, on the debate stage in September 2024, and again in his 2025 inaugural address: that immigrants are pouring in
"from prisons and jails, from mental institutions and insane asylums."
Republican National Convention, July 18, 2024; repeated at the September 10, 2024 debate and the January 20, 2025 inaugural address. He has tied it to the fictional cannibal Hannibal Lecter.
Every major outlet that checked it (PolitiFact, the Associated Press, FactCheck.org, CNN, Reuters) found no evidence that any country empties its prisons or mental institutions into the US. One immigration analyst called it "a total fabrication." He said it No evidence it is true
The disease and "blood" framing runs alongside it. In 2023 he said immigrants were "poisoning the blood of our country," language the Anti-Defamation League and historians noted echoes a passage in Hitler's Mein Kampf. Trump said he "never knew that Hitler said it." At the September 2024 debate he claimed Haitian immigrants in Springfield, Ohio were stealing and eating pets:
"In Springfield, they're eating the dogs. The people that came in, they're eating the cats. They're eating the pets of the people that live there."
Presidential debate, September 10, 2024. Springfield officials and Ohio's Republican governor said there was no evidence; the moderator corrected it live; PolitiFact named it the 2024 "Lie of the Year."
And the dehumanizing register has only sharpened. He has said of migrants accused of murder that "it's in their genes," warning of "a lot of bad genes in our country," and has called migrants "animals" and "not people" (his defenders say those remarks referred to gang members and convicted murderers, not all immigrants, a distinction worth keeping). As president, the language continued into office: his 2025 inaugural address described "millions and millions of criminal aliens" and "dangerous criminals, many from prisons and mental institutions." Documented
The throughline never changes: immigrants are criminal, diseased, insane, less than human. The next section measures each of those claims against the evidence. It is worth saying plainly first. They are not true. Immigrants, including the undocumented, commit crimes at lower rates than native-born Americans, and no country is emptying its asylums into the United States. The rhetoric is not describing the country. It is manufacturing the permission for everything in the parts above.
The case for restriction rests on a set of claims about immigrants. Here they are, each given its strongest version, then measured against the research.
Immigrants commit more crime.
They take jobs and lower wages for Americans.
They don't pay taxes and drain welfare.
We had to do all this. The border was wide open.
They're all here illegally.
They don't assimilate or learn English.
Birthright citizenship is a loophole for "anchor babies."
Step back from the line-by-line and look at what the policy is actually trading away. The American economy's defining strength, its ability to start and scale world-changing companies, runs disproportionately on immigrants.
This is not a story of immigrants taking a fixed pie. Immigrants found businesses at roughly twice the rate of the native-born, and a peer-reviewed study of more than a million firms concluded they act more as job creators than job takers. They are 16 percent of US inventors but produce about 36 percent of US patents once collaboration is counted. The names are familiar: the founders of Google, Nvidia, Intel, Tesla, Stripe, and Moderna's parent were immigrants; Amazon and Apple trace to children of immigrants. (NFAP; NBER; American Immigration Council) Strong evidence
And the fiscal picture rewards patience. A college-educated immigrant contributes more than $800,000 net over a lifetime; the children of immigrants are among the strongest net contributors in the entire population. The state-and-local cost of the first generation is the down payment on that return. (National Academies, 2016) Strong evidence
Here is the part the crackdown forgets: the scientists and founders it turns away do not stop existing. They go somewhere else, and that somewhere is increasingly a competitor that has openly declared it intends to surpass the United States.
The recruiting is already aggressive. When Canada opened a work permit for H-1B holders in 2023, its cap of 10,000 filled in about a day. The European Union launched a "Choose Europe for Science" initiative with 500 million euros to draw researchers, and France stood up programs specifically to host scientists leaving the US. The UK, Australia, and the UAE all run fast-track talent visas. China runs aggressive returnee programs and has a stated national goal to lead the world in artificial intelligence by 2030. (Government of Canada; European Commission; China State Council) Documented
And the outflow has started. New international student visas fell about 36 percent in the summer of 2025; applications from US-based scientists to Europe's main research funder roughly tripled; a Nature poll found about three-quarters of responding US scientists were considering leaving (a measure of intent, not yet of moves); and departures of China-born scientists had already jumped 75 percent after a 2018 crackdown. (Inside Higher Ed; Nature; PNAS) Mixed
Keep it in proportion: the United States still hosts around 60 percent of the world's top AI researchers, a lead built almost entirely on foreign-born talent. This is not a mass exodus. It is the slow draining of the inflow that produced the lead, and leads do not announce the moment they start to slip. (MacroPolo) Strong evidence
The irony is sharp. America became the world's scientific superpower in large part by welcoming the talent other countries cast out, the refugees who fled 1930s Europe and went on to build the Manhattan Project and decades of American advantage. A policy that turns that talent away, toward the very rivals racing to displace the United States, is not protecting American primacy. It is exporting it. Strong evidence
When the United States slammed the door with the immigration quotas of the 1920s, the earnings of native-born workers in the most-affected areas did not rise; they fell, as employers turned to machines and other labor. Restriction did not deliver the gains its backers promised. (Abramitzky, Ager, Boustan et al., NBER) Strong evidence
An honest page owes the other view its best argument.
These points are real, and they argue for a faster, fairer, better-managed legal system, more capacity, more enforcement of actual law, smarter pacing. They do not argue for cutting refugees to a record low, stripping status from people already here legally, or making the legal path nearly impossible. The current policy answers a real problem at the border by dismantling the legal immigration that was never the problem.
The damage from cutting immigration does not show up at a podium. It shows up in the company that is never founded, the patent never filed, the elderly parent whose home aide never arrived, the farm that planted less, the town that kept shrinking, the Social Security gap that widened a little faster. None of it makes the news on the day it happens. All of it compounds.
The argument for the crackdown rests on claims the evidence does not support: that immigrants drive crime, that they take Americans' jobs, that they drain the system, that the border is still open. The strongest true points, that some workers lose out and that local budgets strain, argue for managing immigration better, not for shutting it down. What is actually being cut is the legal immigration and the citizenship that built American innovation and that will pay for an aging country.
A nation that spent a century becoming the place the world's talent wanted to come to is, in real time, telling that talent to stay home, or to take its companies and discoveries to a rival instead. The people who promised this would make Americans richer and safer are selling the opposite of what the record shows. The cost will be paid not by them, but by a smaller, older, slower country a generation from now, wondering where the dynamism went, and why the rivals it once outran suddenly have it.
