WASHINGTON — President Donald Trump's administration has issued a pause on visa appointments for applicants around the world during an ongoing immigration crackdown by the U.S. government in the Republican leader's second term in the White House. A U.S. State Department spokesperson said on Tuesday that it launched a global training initiative at all U.S. embassies and consulates worldwide and that appointments for visa services will be adjusted to accommodate the training. Trump has pursued an aggressive deportation drive and immigration crackdown that includes revocations of visas and green cards and rejection of applications over a. range of reasons like political opinions and pro-Palestinian protests against U.S. ally Israel's assault on Gaza. He says the crackdown aims to improve domestic security. The crackdown has faced some legal setbacks. A U.S. judge on Friday struck down a Trump administration policy suspending the issuance of immigrant visas to applicants from 75 countries, saying that the policy exceeded Secretary of State Marco Rubio's statutory authority.
