美国将暂停75个国家的移民签证办理，谁受影响最大

Group 1 - The U.S. Department of State announced a suspension of immigrant visa processing for applicants from 75 countries, citing potential "public charge" risks, effective January 21 [1] - The suspension is expected to have the most significant impact on family immigration, with nearly 80% of over 600,000 immigrant visas issued in FY2024 going to spouses, children, and other family members of U.S. citizens and lawful permanent residents [1] - Concerns have been raised about the potential impact on overseas tourists, particularly with the upcoming 2026 FIFA World Cup, although the suspension does not apply to non-immigrant visas such as tourism, business, and short-term work [1] Group 2 - Some of the affected countries have already faced travel restrictions under previous Trump administration policies, and certain countries require visa applicants to pay a bond of up to $15,000 [2] - The specific criteria used by the U.S. Department of State to create the list of affected countries remain unclear [3] - The "public charge" provision has been a longstanding aspect of U.S. immigration law, allowing consular officers to deny entry based on the applicant's potential reliance on public assistance, with recent efforts to broaden its interpretation [4]
