1,如果这次签了J2入境美国,是不是就不能换身份为J1了,除非回国两年?
-You can change the J2 to J1 within US, but you will need both your J1 waiver and your spouse's J1 waiver with your J2 waiver to be qualified for future H1 or green card application.
或者只能在美国申请工卡后找位置?
2,如果10月份去签了J2但没入境前拿到J1或者H1的Offer,可以放弃这个J2签证、重新申请J1或者H1签证吗?
-Yes, the J2 visa approval will not affect your H1 or J1 visa application.
3,现在女的名字肯定已经在SEVIS系统了,现在如果有美国的单位愿意给她提供J1,能出DS-2019表吗?
-Yes. Her name in SEVIS as J2 does not affect the new DS-2019 for J1 (irrelevant).
这几个问题请高手解答,谢谢!
