VFX_man update:
I had my interview today and my wife had her test and interview.
She only missed 1 question so she passed with flying colours.
Interview went fast for me, they just verified I was over 55 when I had applied and asked what I did for work and looked over my documents.
Looked at the passport and the travel record document -- I had a lot of trips to the USA and she questioned if I was working down there - no, just border runs and visiting family. I have NEXUS, so no passport stamps - She asked how I obtained all of the USA entries data then - Had requested my border crossing records and used those.
She said the ceremony would be in 2-3 months.
And that was it.
