说来好笑 我唯一的f1签证是2016年读美高时候发的 2018年本科入学因为高中签证仍然有效就没有办新的 2021年的时候5年f1签证过期到现在一直没有回国 2023年研究生毕业后opt上班 现在刚拿到stem opt的ead卡
现在想去加拿大（或者墨西哥或者回国）凭post completion I20和ead卡办个f1 真的被困在美国太久了想短暂的get out一下也方便之后出国 又怕不给签证从此回不来了 （well我的b签明年年中到期）
本科和研究生都是stem的business专业 感觉没有啥敏感的背景 唯一担心的是太久没离开过美国会不会被人想歪 以及现在给我opt的公司不是大厂是个挺小的公司
想请大佬们分析一下风险和利弊 提提建议讲讲要准备啥材料
怕就不要去 帝国这么大还不够你玩吗
我觉得可以去 反正可以用Auto revalidation回
进了使领馆面签了，可就用不了auto revalidation了
哦确实我没仔细看 不过墨西哥被check可以冲回来的 除非签证官给旧签证改了取消章
问题不大。。。你别想太多了
嗯嗯，墨西哥还有可能，加拿大听到的闯回来的不多
你这个专业怕什么，自己吓自己
和楼主几乎相同经历，不过我本科和硕士都是cs。。。正在考虑是回国续还是加拿大续签了再回国，这俩是不是check几率都差不多
怕就不要去, 最多是 check 而已. 我今年三月去温哥华签 F1 check 了 28 天
还真不够 今年开始跟着朋友二刷以前玩过的national park了
而且更多的是想回国看看家人
