I have AOR as yours And I m from US too... Last week I raised webform and got response as follows
You will find below useful information that we hope will help understand the process and current status of your application for permanent residence at the Case Processing Centre in Ottawa, Ontario:
- The background verifications are currently in process.
- The medical examination results on file are valid for you and your spouse and your dependent children.
IRCC is committed to reviewing most permanent resident applications submitted online within a 6-month time frame. Although the processing times may vary, rest assured that we are making the necessary efforts to finalize your application within established processing times.
Does this mean my visa office is CPC Ottawa? The wait is killing me ...
