United States President Donald Trump has sharply escalated his crackdown on immigration with an announcement of a “permanent pause” on migration from “all Third World Countries” late on Thursday.
The president’s remarks came a day after two National Guard members were shot – one of whom has since died from her injuries – in Washington, DC, on Wednesday. An Afghan national has been named as the primary suspect.

“I will permanently pause migration from all Third World Countries to allow the US system to fully recover, terminate all of the millions of Biden illegal admissions,” Trump wrote in a post on his Truth Social platform.
He did not specify what “third world” means and did not name any countries. But the phrase “third world” generally refers to Global South countries that are economically still developing or economically disadvantaged.
He also said “anyone who is not a net asset to the United States, or is incapable of loving our Country”, will be removed from the US.
Trump added that all federal benefits and subsidies to “noncitizens” will end, and he will “denaturalise migrants who undermine domestic tranquillity, and deport any foreign national who is a public charge, security risk, or non-compatible with Western civilisation”.
Earlier this year, Trump announced a ban on visas for citizens of 12 countries and restrictions for citizens of seven more. He has also introduced other restrictions on travel to the US throughout the year.
Here’s what we know.
What has the Trump administration said?
After Rahmanaullah Lakanwal, a 29-year-old Afghan national, was arrested and named as the suspect in the shooting of the National Guard members on Wednesday, Trump called the shooting “an act of terror”.
In an address to the media on Wednesday night, he said: “We must now re-examine every single alien who has entered our country from Afghanistan under Biden.”
Early on Thursday, US Citizenship and Immigration Services (USCIS) announced an indefinite immediate suspension “of all immigration requests relating to Afghan nationals”.
USCIS Director Joseph Edlow then added on X that, “at the direction” of the president, he had ordered “a full-scale, rigorous re-examination of every green card for every alien from every country of concern”.
“The protection of this country and of the American people remains paramount, and the American people will not bear the cost of the prior administration’s reckless resettlement policies,” Edlow said.
Edlow’s office told US media that the countries for which citizens with green cards will be reviewed would be those on the Trump administration’s June travel ban list.
In June, to “protect the United States from foreign terrorists and other National security and public safety threats”, the Trump administration announced that foreign nationals from 19 countries would face a full travel ban or partial restrictions.
Countries with a full ban in place are Afghanistan, Chad, Democratic Republic of the Congo (DRC), Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Myanmar, Somalia, Sudan and Yemen. Those with a partial ban in place – some temporary visas are still allowed – are Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan and Venezuela.
On Thursday night, Trump said on Truth Social he would introduce a “permanent pause” on immigration from all “Third World Countries”.
What does a ‘permanent pause’ in immigration mean?
It is unclear.
“In ordinary English, ‘permanent pause’ sounds final, but under immigration law, the term has no defined meaning,” Abhishek Saxena, a New Delhi-based advocate practising in the Supreme Court of India who also handles international immigration consultations, told Al Jazeera.
“Practically, ‘permanent pause’ typically means an open-ended restriction with no stated end date, but not a legally irreversible condition,” he added.
According to the US Immigration and Nationality Act (INA), the president may suspend the entry of immigrants for a fixed period, indefinitely or until the president modifies or lifts the proclamation. This can, however, be challenged. “If any indefinite pause is violating laws passed by US Congress, then such ban or pause can be challenged in a court,” said Saxena.
Roberto Forin, acting director of the Geneva-based Mixed Migration Centre (MMC), said the Trump administration’s vagueness over who these policies apply to and what he means by “permanently pause” or “Third World” is intentional.
“Keeping it undefined allows the administration to indiscriminately intimidate migrant communities in the US and around the world, while giving itself the prerogative to use this ban as another tool in its transactional approach to foreign policy,” Forin told Al Jazeera.
“I would expect the ban to disproportionately affect poorer countries, while sparing those that can offer something in exchange, such as natural resources or other strategic benefits,” he said.
“The objective of such announcements is to signal toughness, shift the narrative, instil fear and dehumanise migrants – regardless of the practical implementation and eventual legal outcomes,” he added.
How will people from such countries who are already living in the US be affected?
It is unclear how people from those countries will be affected until the names of the countries are listed and the immigration measure is implemented.
However, an August report by the Washington, DC-based American Immigration Council concluded that people from the 12 countries on Trump’s June 2025 full travel ban list will “not be able to see family members living abroad”.
“Under the June order, existing visas cannot be revoked, but those who need to leave the United States and renew their visas after they expire could be subjected to the ban instead of being allowed to return,” the report said.
Saxena said a restrictive immigration policy can indirectly affect people in the US in several other ways as well.
“Firstly, it will lead to increased scrutiny of pending applications. USCIS may subject applications from nationals of the affected countries to added background checks, longer security screening, or temporary holds,” he said.
“Secondly, history shows that when a country is placed under heightened security review, [visa] processing times frequently increase,” he noted.
“Lastly, although the government cannot revoke existing residency statuses arbitrarily, it may audit past immigration filings for fraud, misrepresentation, security concerns, or ineligibility under existing statutes,” he added.
Saxena said Trump’s announcement that he will pause immigration from “Third World Countries” would also likely prevent spouses, children, and parents who are abroad from entering the US until the proclamation is lifted.
“This creates long-distance separations, delays in family-based immigration petitions and interruption of family reunification programmes,” he said.
“However, people already inside the US cannot be separated from their families merely because a country is listed in a proclamation. Family-unity principles under the Constitution and the INA apply once a person is inside US territory,” he added.
What if you have a green card?
On Thursday, the Trump administration told journalists that it intends to re-examine all green cards held by people from the countries on the June 2025 travel ban list. However, it is not clear how the process will work or whether green cards could be revoked or even cancelled.
A green card is a US immigration document which allows an immigrant to permanently reside and work in the country.
US immigration judges have the power to revoke green cards and to deport people from the country if there are serious grounds, such as being found guilty of grievous crimes like murder or rape.
The government can also deport an immigrant on these grounds, including if they consider the person “a threat to public safety or if the person violates their visa”.
However, according to Saxena, the government “has no legal authority to revoke green cards without following due process. Any revocation must follow strict statutory procedures and satisfy due-process requirements.”
Last year, the US Immigration and Customs Enforcement (ICE) agency detained pro-Palestine activist Mahmoud Khalil on the “basis of his speech” while he was protesting against Israel’s genocidal war on Gaza at Columbia University. Khalil was a permanent US resident at the time, but ICE accused him of omitting information on his green card application.
In September, a US immigration judge ordered that Khalil should be deported to Algeria or Syria, but this has not yet happened.
What other steps has Trump taken this year to restrict immigration?
Besides green card re-examinations and announcing travel bans on citizens of some specific countries, Trump also froze refugee admissions shortly after he resumed office in January.
“The United States lacks the ability to absorb large numbers of migrants, and in particular, refugees, into its communities in a manner that does not compromise the availability of resources for Americans, that protects their safety and security, and that ensures the appropriate assimilation of refugees,” the White House said in a statement in January.
Then, at the end of October, the Trump administration announced the lowest refugee admission cap in the country’s history, limiting entry to just 7,500 people for the fiscal year 2026.
On November 25, according to a memo seen by the Reuters news agency, the Trump administration ordered a review of all refugees allowed into the country under the previous Joe Biden administration, and recommended that their permanent residency applications be paused.
According to the memo, which was reportedly signed by USCIS chief Eldow, the status and applications of about 233,000 refugees who entered the US between January 20, 2021 and February 20, 2025, would be reviewed. The memo cited Trump’s January order on freezing refugee admissions due to national security as a reason.
The US has also cut foreign aid for refugees in host countries.
The Trump administration has also targeted skilled migrant workers in an effort to protect US citizens’ jobs. In September, it increased the application fee for H-1B visas to $100,000 per application. The visa is used by companies in the US hiring overseas workers.
In October, the US Chamber of Commerce filed a lawsuit against the Trump administration for the visa application fee rise, claiming it could harm businesses. The case is pending in the Washington, DC district court.
What does this mean for refugees generally?
“Taken together, these measures, especially if they trigger a ‘race to the bottom’ among governments, could have devastating consequences globally, including in countries already ravaged by conflict and violence,” Forin said.
“We see this happening in Europe as well, from the system the UK has tried to establish to outsource asylum procedures to Rwanda, to the centres Italy tried to set up in Albania, and none of these have worked, because they were blocked by courts at every step.”
“Unfortunately, they have all contributed to the dehumanisation of refugees and migrants, depicting them simply as a threat or a burden, rather than as human beings in need of protection or deserving of a chance at a better future,” Forin added.
