我们的绿卡到明年7月份到期，今年7月份申请延期，到现在为止只收到receipt, 还没有收到打指纹通知，请问：
1. 现在绿卡延期要多久？-10 to 12 months or more. 怎么现在还没有收到打指纹通知啊？-Due to Covid 19, USCIS may just use your old fingerprint in the system for the green card renewal in these days, but they still charge your biometrics fee.
2. 等绿卡延期可以买房搬家更换地址吗？-Yes, but need to inform USCIS about the address change for resident address update and the I-90 case address update by filing AR-11 online. Then, call USCIS to make sure the address change in the system for I-90.
3. 等绿卡期间可以同时申请移民吗？-What do you mean?
谢谢！
