Joseph Edlow, director of the US Citizenship and Immigration Services (USCIS), said that the president had instructed him to conduct "a comprehensive and thorough reassessment of each green card for each foreigner from each country of concern," the Dunyo news agency reported, citing CNN.

When asked for additional information, including which countries are considered "of concern," USCIS pointed CNN to the 19 countries listed in the presidential proclamation from June.

These countries include Afghanistan, Chad, the Democratic Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Myanmar (Burma), Somalia, Sudan, Yemen, Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela, which were targeted in June. a complete or partial ban on travel to the United States.

The USCIS also said that when screening immigrants from these countries, the agency will now take into account "negative, country-specific factors," including whether the country is capable of issuing reliable identity cards.

This statement was made after an Afghan citizen shot dead two National Guard soldiers in Washington, DC. One of the soldiers later died of her injuries in the hospital.

President Donald Trump said the shooting highlighted a serious threat to national security. He later added that his administration would work to permanently suspend migration from all "third world countries."

In a published statement by the head of USCIS on social media about a large-scale review of the green card program, this attack was not explicitly mentioned. There are also no other details about what the re-verification will look like.

Last week, USCIS announced a review of all refugees accepted under former President Joe Biden. The United States recently suspended processing immigration applications from Afghans, saying the decision was related to an expected review of security protocols and checks.
