上次您说过 我朋友第一次入境时会得到一个the green card stamp on the passport,然后移民局会寄绿卡来。 有个问题是,不知他入境后在等待这个绿卡期间,可以先去加拿大,再回美国取绿卡?
-Yes, he can use the green card stamp for the travel to Canada and come back because the GC stamp has the same function as the physical GC.
还是必须等到收到那个绿卡后才能离开美国?
另外就是他入境时可以填申请SSN的表格吗?
-Yes.
或可以在收到绿卡前,用STAMPED GREEN CARD ON THE PASSPORT 先递交申请SSN的表格?
-Yes too.
