The Trump administration has announced a sweeping review of all green cards issued to nationals from 19 “countries of concern,” but Nigeria—despite being newly listed as a Country of Particular Concern—is excluded from the move.

USCIS Director Joe Edlow announced the new directive, stating on X that President Trump ordered a “full scale, rigorous re-examination” of all green cards belonging to immigrants from the affected countries. The list includes Afghanistan, Burma, Chad, Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, Yemen, Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan and Venezuela.

USCIS clarified that the renewed vetting will factor in each country’s security risks and its ability to issue reliable identification documents.

The move comes after authorities identified Rahmanullah Lakanwal, a 29-year-old Afghan national and former CIA asset, as the suspect in the shooting of two National Guard members in Washington, DC. The Department of Homeland Security has since suspended all immigration processing for Afghan nationals pending a full review of security protocols.

DHS also announced a fresh review of all asylum approvals granted under the previous Biden administration.

Afghan community leaders have condemned the attack but urged the government not to punish thousands of eligible Afghan immigrants because of one individual’s actions. More than 190,000 Afghans have resettled in the US since the 2021 military withdrawal.

While green cards grant permanent residency, they are separate from refugee and asylum programs—although refugees must apply for a green card after one year in the US.
