请教8老师：目前绿卡延期递交后大概多久能收到打指纹的通知？三月中旬收到的移民局receipt notice。是个I-797 notice。因为在做贷款，但是银行说必须要I-797C。这两个I-797和I-797C有什么区别？
--Same. In your case, USCIS only issued I-797 for I-90 Receipt Notice, not I-797C. Read the Notice carefully and it should indicate that your green card is automatically extended for one year from the date your green card expires. Then, show it to the Bank.
有人说打指纹的通知就是I-797C。想问问看还需要等多久？多谢啦！
-Yes, biometrics appointment notice is I-797C, but it is not I-90 Receipt Notice.
