WASHINGTON (AP) — The State Department said Wednesday it will suspend the processing of immigrant visas for citizens of 75 countries whose nationals are deemed likely to require public assistance while living in the United States.

The State Department, led by Secretary Marco Rubio, said it had instructed consular officers to halt immigrant visa applications from the countries affected in accordance with a broader order issued in November that tightened rules around potential immigrants who might become “public charges” in the U.S.

The suspension, which will begin Jan. 21, will not apply to applicants seeking non-immigrant visas, or temporary tourist or business visas.

“The Trump administration is bringing an end to the abuse of America’s immigration system by those who would extract wealth from the American people,” the department said in a statement. “Immigrant visa processing from these 75 countries will be paused while the State Department reassess immigration processing procedures to prevent the entry of foreign nationals who would take welfare and public benefits.”

The list includes Russia, Iran and Afghanistan, as well as multiple countries in Africa, according to the State Department.

President Donald Trump’s administration has already severely restricted immigrant and non-immigrant visa processing for citizens of dozens of countries, many of them in Africa.
