I tried changing but i could not find the option to change. I am happy for you that you are done with this painful ,torturous and disastrous process. Thanks for letting me know about the email id although I can only send an email to the same address if my DM is made but i will still send an inquiry. lets see.Consider changing your display name for this forum as it might help . Worth a shot right... hehe
We are July 2019 applicant and finally took oath in May 2021 almost two years of process where everything on file was completed since March 2020 but still it took them 15 months to send oath invite. In our case there was no FP request or any delay with BG etc but still file was on hold for no reason... I think mostly those people got impacted who did their test before the lockdown and were waiting for oath invite. Once they resumed work they started working on those applications which were test ready instead of the ones which were oath ready. Anyways I am glad that its finally over for us.
Trust me I understand the frustration and anxiety you must be going through. I sincerely hope that you get your oath invite soon.
Though you might already have tried this but did you send an email to the email address you got test invite from? In my case phone call or web forms always got me same standard response however when I sent them email to same email address that I received test invite last year it worked. They replied back same day and told me they would try to schedule for oath within a week and then they actually did. Surprise surprise
