感谢8老师!我目前绿卡未到期,再请教i751收据大概要多久呢?
-One to two months, case by case.
申请i131不知又要多久呢?
-Case to case. You may file I-131 now even if you don't have the I-751 receipt. But nromally you need to conduct the biometrics for the I-751 and I-131. After you doncudct these two biometrics, you can leave US.
You may request expedited processing for biometrics for the reemtry permit. See:
