President Trump's second term is tightening legal immigration pathways, including student visas and green card applications. New policies require many temporary visa holders to apply for permanent residency from abroad, increasing delays and uncertainty. These measures aim to enhance national security and protect American jobs, but critics warn of negative economic impacts.

The change could affect hundreds of thousands of people a year and potentially reduce legal immigration further.

It's just the latest step by the Trump administration to make legal immigration to the United States more difficult.
