我目前人在國內工作，綠卡快到期了，想了解一下green card renewal遞交申請後，對方一般多長時間通知打指紋，預約時間一般幾個禮拜。以便購買大致日期的機票。我家住在Connecticut ，不知不同的office處理的時間是不是也不同？
-It is case by case. Hard to say. Normally it takes about 5 to 8 weeks.
另外綠卡renewal打好指紋後是否可以離開美國？-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.
非常感謝！
