The United States has deported more than three million undocumented migrants since President Donald Trump returned to office, according to a fact sheet released by the White House.

The administration also claimed that no illegal migrants had been released into the country for 15 consecutive months, highlighting the figure as evidence of its tougher approach to immigration enforcement.

According to the White House, Trump signed an executive order during his first week back in office declaring a crisis at the US southern border and directing measures to tighten immigration controls.

The administration said thousands of those deported had been convicted of violent crimes, while also launching what it described as a “denaturalisation surge” targeting people who allegedly obtained US citizenship fraudulently.

It said legal action had been initiated against 88 people who were allegedly ineligible for the citizenship they obtained.

The White House further claimed that taxpayer-funded benefits had been terminated for more than 1.4 million undocumented migrants who were improperly receiving public assistance.

On visa restrictions, the administration said it had strengthened screening procedures and paused visa processing for 75 countries it classified as high-risk.

It also said measures had been taken to remove tens of thousands of undocumented migrants from voter rolls in several states, stressing that voting in US elections was reserved for American citizens.

The administration said it had also reformed the US citizenship test to assess applicants’ knowledge of American history, government and values more thoroughly.

The White House further pointed to executive orders signed on August 6 aimed at ending birth tourism and clarifying eligibility for birthright citizenship following a Supreme Court ruling.
