1. 像您建议的,如果我父母来美之前放弃绿卡,然后在国内申请B2签证获得批准的可能性大吗?
-Yes.
他们曾经有过绿卡会对B2申请获批有负面影响吗?
-It should not affect it.
2. 您说B2入境之后最好在美国呆3个月以上再重新申请绿卡,如果是入关时放弃绿卡拿到B2,那个B2通常会有3个月以上的停留时间吗?
-I think so.
3. 您说入关时放弃绿卡,不是100%会给B2签证。如果不给B2签证,是什么结果,会被禁止入境吗?
-It is possible the officer may not allow them to enter US and ask them to return to China directly from the airport. Of course, it is just possible and it is difficult to predict what will happen.
谢谢!!
