Thousands of Afghans have arrived in the United States since the hurried evacuation of Afghanistan began in mid-August, including many who helped U.S. forces during its 20-year involvement in the country's war.
WHY IS THE U.S. MILITARY EVACUATING AFGHANS?
President Joe Biden said the United States aimed to evacuate 50,000 to 65,000 Afghan allies before an Aug. 31 deadline for U.S. withdrawal, Biden's estimate appeared to refer to Afghans who have applied for a humanitarian visa known as a Special Immigrant Visa (SIV), and their family members.
The U.S. government has declined to say how many Afghans have arrived in the United States since the evacuation from Kabul began or the immigration status of those people.
WHAT IS THE SPECIAL IMMIGRANT VISA PROGRAM?
SIV's are available to certain Afghans who aided U.S. forces as interpreters and translators, as well as in other roles, and who fear reprisals by the Taliban, the Islamist militant group that swiftly seized power 11 days ago.
An estimated 5,000 SIV applicants have already been evacuated from Afghanistan, according to a report released on Wednesday by the Association of Wartime Allies, a group advocating for SIV applicants in Afghanistan and Iraq.
The group estimates that 65,000 SIV applicants and family members remain in Afghanistan.
WHO ARE THE AFGHANS ARRIVING IN THE UNITED STATES?
U.S. military evacuation flights from Kabul have carried U.S. citizens, lawful permanent residents, Afghan SIV applicants and other vulnerable Afghans, according to the Pentagon.
Among the Afghans entering the United States are people with approved SIVs and applicants to the program.
Other arriving Afghans may seek U.S. asylum or similar forms of relief, advocates say.
Afghans who lack valid immigration status when they arrive in the United States can be permitted to enter for a temporary period via "humanitarian parole."
The Biden administration has not said how many Afghans have been paroled into the United States, but advocates expect many arrivals will lack visas and require parole.
WHAT HAPPENS TO AFGHANS WHEN THEY ARRIVE IN THE UNITED STATES?
U.S. evacuation flights so far have landed at Dulles International Airport in Virginia.
U.S. citizens and lawful permanent residents can go on to their destinations after they have been tested for COVID-19. SIV-eligible Afghans and other Afghan arrivals go to U.S. military bases in Virginia, Texas, Wisconsin and New Jersey for processing, according to people familiar with the process.
Afghans sent to the military bases receive a health screening and help in applying for work authorization, along with other services. The processing can take anywhere from a day to a week or more, a refugee staffer working at Fort Lee in Virginia told Reuters.
After processing at the military bases, Afghans will be connected with a U.S. refugee resettlement organization, a senior U.S. official said.
The groups provide SIV-eligible Afghans and others with housing, furniture and food, and help them adjust to life in the United States.
ARE THE ARRIVING AFGHANS VETTED FOR POSSIBLE SECURITY THREATS?
Afghans seeking SIVs must complete a 14-step application process that includes a visa interview and security screening.
The Biden administration has said that SIV applicants further along in the application process have been allowed to enter the United States.
