What recent action has the Trump administration taken regarding Biden-era immigration programs?

The Trump administration has suspended immigration applications for migrants from Latin American countries and Ukraine who were admitted under Biden-era programs. The pause affects hundreds of thousands of people from crisis-affected nations including Haiti and Venezuela. Administration officials cite concerns about fraud and potential public safety risks as justification for this decision. Additionally, legal services for unaccompanied minors are reportedly at risk, which could impact their immigration court proceedings.
