请教8老师:申请到绿卡后,在国外读大学,怎么维系绿卡身份?
帮一个朋友打听个情况: 他有一个男孩,生长在加拿大,一直跟妈妈住,现在在加拿大读大一。如果他爸爸申请他美国绿卡,在读大学期间,他怎么维系美国绿卡身份?
Re-entry permit 是不是唯一的出路?
-Yes. He can apply for reentry permit to stay in Canada for > one year < two years, then come back to US to renew it before it expires. He can leave US after he conducts the biometrics for reentry permit application , not need to wait for the reentry permit approval.
