Stony Brook 大学发布假期出行指引，留学生返美前须查旅行签名与签证
纽约州 Stony Brook 大学签证与移民服务处 11 月 6 日发布假期出行指引，提醒计划在感恩节与寒假期间国际旅行的留学生，离境前仔细核查移民文件，以保证顺利返美。
指引要点包括：护照有效期一般应在计划返美日期之后至少六个月；签证须为现行身份、未过期且尚有入境次数；赴加拿大或墨西哥 30 天及以内的短途旅行，可能符合自动签证再验证、凭过期签证返美，但有资格限制。旅行签名方面，继续就读的 F-1 与 J-1 学生签名一般有效一年，OPT 与 STEM OPT 学生为六个月；签名将过期的，须在出发前至少 5 至 7 个工作日提交旅行签名申请。
该校提醒，返美入境后应到海关与边境保护局 I-94 网站核对入境记录，确认身份类别与停留期限无误。该校签证与移民服务处 12 月 23 日至 1 月 15 日远程办公，时间为上午 9 时至下午 4 时。
Stony Brook Issues Holiday Travel Guidance: International Students Told to Check Travel Signatures and Visas
Stony Brook University's Visa and Immigration Services office issued holiday travel guidance on November 6, urging international students planning Thanksgiving or winter-break travel to review their immigration documents carefully before departing the United States to ensure a smooth return.
Key points: passports should generally be valid for at least six months beyond the intended return date; visas must reflect the student's current status, be unexpired and have a remaining entry; short trips of 30 days or less to Canada or Mexico may qualify for reentry on an expired visa through Automatic Visa Revalidation, subject to eligibility restrictions. Travel signatures are generally valid for one year for continuing F-1 and J-1 students and six months for students on OPT or STEM OPT; students whose signature will expire before their return should submit a request at least five to seven business days before departure.
After reentry, students should check their Form I-94 record on the CBP website to confirm the admission class and duration of status are correct. The university's Visa and Immigration Services office will operate remotely from December 23 through January 15, from 9 a.m. to 4 p.m.
