This office was not able to complete the card with the documentation initially submitted. A request for biometrics will be submitted, please allow 4 to 6 weeks for receipt.（我去年打過指紋了）
請教老師，依郵件為準，還是以網上查的狀態為準？我的卡是不是寄出來了？
-Online status check is just for you reference. The mail is more accurate. It is normal in some cases the applicant is required to do the fingerprinting again even if after the I-485 is approved (this fingprinting is for green card production, not for background check. If you worry too much, you may just visit the USCIS local office to see what is really going on.
