在线咨询 留学评估

OPT 是美国留学生毕业后重要的实习工作许可，STEM 专业可享受最长 36 个月 OPT。受签证新规影响，学生需要在项目结束后 30 天缓冲期之内递交 OPT 申请，超时将失去申请资格。不少院校提示学生，尽量在读期间就完成实习对接，不要等到毕业之后才匆忙寻找岗位Office of ...。 安侨留学提醒赴美学子，入学就要了解本校国际学生办公室关于 OPT 的办理流程，记好关键时间节点。找实习的时候，确认雇主满足 OPT 雇佣资质，避开不合规岗位。就算未来计划回国发展，OPT 实习经历也会为国内求职增加含金量。就读敏感理工科专业，提前确认研究方向，规避签证与身份方面潜在风险。
