期间因为我们搬了家,移民局的后来的文件也没收到。他们在美多呆了三个月,现在想再次来美,不知是否有影响?
-No. But they may need to provide the I-539 filing receipt notice (extention applicaiton receipt) for the visa application./
是否我们要和移民局联系得到当时延期批准的文件?
-Not need the approval notice, but need to provide the filing receipt (see above).
另,他们来准备短期停留,主要是参加孙子毕业典礼,当然也看看我们,是由他们孙子发邀请还是我们子女发邀请好呢?
-You are better because you have income to cover their costs.
多谢各位老师答疑解惑!
