美国正在扩大旅行限制,从2026年1月1日起将尼日利亚等15个国家的国民也包括在内,理由是安全顾虑和签证超期率高。 The U.S. is expanding travel restrictions to include nationals from 15 additional countries, including Nigeria, effective January 1, 2026, citing security concerns and high visa overstay rates. 此举中止了这些国家公民的合法移民申请,例如绿卡和公民身份,尼日利亚受到部分限制。 The move suspends legal immigration applications like green cards and citizenship for citizens of these nations, with Nigeria facing partial restrictions. 虽然现有签证仍然有效,但申请人面临严格的审查、较长的处理时间和更高的拒发风险。 While existing visas remain valid, applicants face heightened scrutiny, longer processing times, and a higher risk of denial. 该政策影响学生、专业人员和家庭,干扰学术方案和商务旅行,导致取消假日计划,并引起对绿卡持有者重新入境的担忧。 The policy affects students, professionals, and families, disrupting academic programs and business travel, and has led to cancellations of holiday plans and concerns over re-entry for green card holders. 白宫引述国家安全与审查挑战, 但批评者认为政策危害美国-尼日利亚关系, 破坏教育与经济联系。 The White House cites national security and vetting challenges, but critics argue the policy harms U.S.-Nigeria relations and undermines educational and economic ties.
