The U.S. president unveiled sweeping new immigration proposals in a fiery social media post, using stark language to signal a dramatic escalation of his hardline agenda. Trump vowed that he would “permanently pause migration from all Third World countries”, declaring that new arrivals from poorer nations would be halted indefinitely under his plan. The president said this move was needed to allow the United States to “fully recover” from what he described as the harmful economic, social, and security impacts of past immigration waves.
