WASHINGTON (Reuters) -U.S. President Donald Trump's administration will revoke the temporary legal status of 530,000 Cubans, Haitians, Nicaraguans and Venezuelans in the United States, according to a Federal Register notice on Friday, the latest expansion of his crackdown on immigration. The move cuts short a two-year "parole" granted to the migrants under former President Joe Biden that allowed them to enter the country by air if they had U.S. sponsors. Trump, a Republican, took steps to ramp up immigration enforcement after taking office, including a push to deport record numbers of migrants in the U.S. illegally.
