The decision came in a lawsuit brought by immigrant rights groups, immigrant visa applicants and US citizens sponsoring family members from affected countries.The State Department introduced the suspension in January, blocking the issuance of immigrant visas to applicants from 75 countries. The administration had argued that people from those countries were at a higher risk of becoming a “public charge” and relying on government resources in the United States.Judge says State Department exceeded its authorityVargas, a Biden appointee, described the policy as “patently unlawful” and said it improperly gave the secretary of state authority over consular officers' processing of immigrant visas.Also read: Could working in the US after graduation get costlier?

His administration has argued that tougher immigration measures are necessary to protect national security and reduce pressure on government resources.Immigrant rights groups, however, have argued that several elements of the crackdown violate constitutional protections and due process.For applicants from the countries covered by the January policy, the immediate impact of the ruling will depend on how the State Department responds and whether the administration seeks to appeal the decision.The case does not amount to a blanket change to all US visa categories. It specifically concerns the policy suspending the issuance of immigrant visas to nationals of the 75 designated countries.
