1. 我妻子是H4,如果让她在3月底之前转F1,对她来说会不会有什么问题?(会不会应为OOS被拒)。
-No problem. She need to provide the copies of your H1 approval notice with I-94 and your recent 3 month paycheck stubs and her approval notice (if any) and the H4 I-94 for the F-1 application.
她转F1需不需要境外激活?
-No.
2. 我如果要转F2的话,是必须等我妻子的F1批准之后才能转,
-Not need.
还是可以和她同时提交转身份的申请?
-Yes.
3. 如果要境外激活H1b的话,必须会中国签证吗?还是可以在加拿大/墨西哥签?
-Canada is OK if you do it before your current H1 I-94 expires, not sure in Mexico.
4.境外激活H1b有什么风险吗,会被拒签吗?(我还没有提交I140)
-Don't think there will be a problem though it is not 100%.
