Hello Family, Congressman got an email from USCIS on Friday about my case: October 2018 filler
We have checked into your constituent's case and have been assured that USCIS is aware of your inquiry and is monitoring progress related to it.
However, unresolved issues in your constituent's case require a thorough review before a decision can be rendered.
Unfortunately, we cannot speculate as to when this review process will be completed.
We realize that your constituent may feel frustrated by delays related to his case.
USCIS must weigh individual inconvenience against the broader concerns of public safety and national security.
Once further action is taken, a decision or notice of action will be sent to the address of record.
We hope this information is helpful.
What does that mean?
