我目前人在国内工作，绿卡快到期了，想了解一下green card renewal递交申请后，对方一般多长时间通知打指纹，预约时间一般几个礼拜。以便购买大致日期的机票。我家住在Connecticut ，不知不同的office处理的时间是不是也不同？
-It is case by case. Hard to say. Normally it takes about 5 to 8 weeks.
另外绿卡renewal打好指纹后是否可以离开美国？-Yes, but you had better bring I-90 extension filing receipt notice and your passport to the local USCIS Office to get the I-551 stamp (green card stamp) to travel in case you do not receive the renewed green card on time or it is lost during the mail. The stamp is valid for one year.
非常感谢！
