f1留学签证有效期,f1签证一年有效到期怎么办
匿名用户
F1 留学签证的有效期通常是学生在 SEVIS(学生和交流访问学者信息系统)中记录的项目结束日期后 60 天。具体有效期可能因个案而异,具体取决于以下因素:
学生的项目开始和结束日期
签证签发日期
美国大使馆或领事馆的政策
F1 签证持有人可以在其签证到期之前进入美国,但他们只能在项目开始日期之前 30 天内进入。如果学生希望在项目开始日期之前超过 30 天进入美国,他们需要向美国海关和边境保护局(CBP)申请提前入境。
F1 签证有效期到期后的处理方式
选项 1:申请延期
如果您希望在现有的 F1 签证到期后继续在美国学习,您可以向美国公民及移民服务局 (USCIS) 申请延期。
申请必须在签证到期前 120 天内提交。
您需要向 USCIS 提交以下文件:
I539 表格(入境申请延期和变更身份)
护照
I20 表格(学生和交流访问者信息)
学校证明您仍是全日制学生
费用
选项 2:I20 转学
如果您决定转到另一所学校,您可以让新的学校为您签发新的 I20 表格。
将 I20 发送给 USCIS,他们会更新您的 SEVIS 记录以反映您新的学校。
您不需要提交额外的申请或费用。
选项 3:离开美国
如果您不打算在美国继续学习,您必须在 F1 签证到期后 60 天内离开该国。
超过 60 天的停留将被视为非法逗留,可能会导致遣返和/或未来签证申请的困难。
其他考虑因素
OPT 实习期:如果您持有 F1 签证并在 STEM 领域学习,您可能有资格在毕业后进行为期 12 个月的 OPT 实习期。您的 OPT 实习期会延长您的 F1 签证有效期。
H1B 签证:如果您希望在美国工作,您可以在持有 F1 签证后申请 H1B 签证。H1B 签证允许外国专业人士在美国工作长达六年。
签证状态违规:逾期逗留或其他签证状态违规可能会导致遣返。
请务必在 F1 签证到期前咨询国际学生办公室 (OISS) 或移民律师,以讨论您的选择和程序。
