Immigration lawyers and authorities say arrests of Afghans are on the rise following the shooting of two National Guard members in Washington, D.C..

The suspect in the attack is an Afghan national.

Since the Nov. 26 Guard shooting, The Associated Press has tracked roughly two dozen arrests of Afghan immigrants, most of which happened in Northern California.

In Sacramento, home to one of the nation’s largest Afghan communities, volunteers monitoring ICE activities say they witnessed at least nine arrests at the federal building last week after Afghan men received calls to check in there.

Many of those detained had requested asylum at the U.S.-Mexico border in the last two years. Others were among the 76,000 Afghans brought to the U.S. under Operation Allies Welcome, created by former President Joe Biden's administration after the chaotic withdrawal of the U.S. from their country.

White House press secretary Karoline Leavitt said Dec. 1 that the Trump administration is “actively reexamining” all the Afghan nationals who entered the U.S. during Biden’s administration.

The AP couldn’t independently determine each of the Afghans' immigration statuses or the reasons put forward by authorities for their arrests. In one case, the man had been arrested twice on suspicion of domestic violence, according to the government.

Tricia McLaughlin, a spokesperson for the Department of Homeland, said in an email that the agency "has been going full throttle on identifying and arresting known or suspected terrorists and criminal illegal aliens that came in through Biden’s fraudulent parole programs and working to get the criminals and public safety threats OUT of our country.”

Rahmanullah Lakanwal, the 29-year-old Afghan suspect in the shooting, was granted asylum earlier this year, according to advocate group #AfghanEvac.

Since the shooting, the U.S. government introduced sweeping immigration changes, including pausing asylum applications and requiring increased vetting for immigrants from certain countries.

The administration also took steps specifically targeted at Afghans, including pausing all their immigration-related applications and visas for Afghans who closely helped the war effort.

Those who work with Afghans say the stepped-up enforcement amounts to the collective punishment of a population, many of whom risked their lives to protect U.S. troops.
