A US federal judge has ruled that the Trump administration's $100,000 fee on new H-1B visa applications is lawful, upholding the president's authority to impose the charge. The decision supports the administration's efforts to curb immigration and prioritize U.S. workers, though it has been met with disappointment by the U.S. Chamber of Commerce and other business groups who argue it makes visas unaffordable. Separately, the Department of Homeland Security is changing H-1B selection rules, replacing the lottery with a system prioritizing higher wages and skills.
