請教: i485面談後收到i797 - 移民

請教 :
面談後收到i797, 上面說
CaseTyype : I485 - application to register P.R. residence or adjust status

The above application has been approved. Prior to receiving your P.R. card you
may be required to report for biometrics processing(photo or fingerprint/sign
ature). Please do not take any action at this time. if you are required to rep
ort for this processing, you will receive another notice advising you of the d
ate, time and location to appear.

If you have not received your P.R. card or the above mentioned notice to appea
r for biometrics processing within 90 days, please call this office at the num
ber listed below.

字面上意思我大約看得懂，想再請教確認一下，這是表示I485已經通過，但在收到綠卡前
可能還要按指紋的意思嗎？ 所以，下一封信可能就是(1)收到綠卡，或（2)收到biometri
cs process的通知。是這樣嗎？
