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.

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.

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”.

Early on Thursday, US Citizenship and Immigration Services (USCIS) announced an indefinite immediate suspension “of all immigration requests relating to Afghan nationals”.

Effective immediately, processing of all immigration requests relating to Afghan nationals is stopped indefinitely pending further review of security and vetting protocols.

“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.
