大爷们，这是CIS给我的邮件，请问我是否有什么问题了？

The processing of your case has been delayed. A check of our records
establishes that your case is not yet ready for decision, as the required
investigation into your background remains open.

Until the background investigation is completed, we cannot move forward on your
case. These background checks are required to be completed on all applicants
who apply for the immigration benefit you are seeking. We will make every
effort to make a decision on this case as soon as the background checks are
complete. If you do not receive a decision or other notice of action from us
within 6 months of this letter, please contact us by calling our customer
service number provided below
