A report by Reuters says that the U.S. State Department has said it will soon run out of visas for interpreters and other Afghans who have worked for the U.S. government during the past 15 years of Washington’s anti-terror mission in Afghanistan.

According to the Reuters report which was published on Thursday, at least one U.S. senator, Democrat Jeanne Shaheen, said any decision to let the program lapse sends a message to allies in Afghanistan that the United States is not supporting them. 

She pledged to immediately introduce legislation to provide more visas.

"It's both a moral and practical imperative that Congress right this wrong immediately," Shaheen said in a statement.

Her office said more than 10,000 applicants are still in the process of obtaining visas, the report mentions.

Shaheen and Republican Senator John McCain led a failed effort last year to pass legislation extending to 4,000 more people an existing special immigrant visa program for Afghans who assisted U.S. forces, often risking their lives.

The United Sates’ National Defense Authorization Act passed late last year added 1,500 visas to the program, while tightening requirements for eligibility.

This comes after thousands of Afghans, who have worked with U.S. forces in the country, have applied for the United States special immigration visa program and are waiting for their fate.
