I think I faced a unique issue on my test. When I started my test, test site used my infra red camera instead of my regular camera. So it did capture in b/w with some distortion. My test was in April and after few days test status changed to complete. And then again few days back test status changed to progress. Today I saw update that I have to take the test again. But no email or anything yet.
They took 4 months to review the test. And even after taking re test, I think it is going to be another for 4 month and probably I get my citizenship after 8-9 months. And I got my AOR of Aug 2019. So probably three year for citizenship !!
