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.（我去年打过指纹了）
请教老师，依邮件为准，还是以网上查的状态为准？我的卡是不是寄出来了？
-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.
