He shot down my plans to launch boss mode by being on top of things (and also that I left my butt exposed through my own mistake). He was very good and fully aware of my letter of complaint. Yesterday was a holiday here, so we had been told we were getting a September interview (annoyingly) but at least they gave us the earliest possible appointment in September. So in all, I think SF FO have tried to put things right for us somewhat.
We had three interview slots, the first being at 7:45am. The IO actually came out to the waiting area and came directly to us (he had looked at our photos in our pack). A bit of smalltalk, some playful comments to Miss Britsimon. He swore us and then started with questions. AoS is a bit different to CP. The I485 has a bunch of standard questions, he basically read through every one of those asking us to confirm the answers as given. He asked to see ID, passports, recent payslips, job offer letter, and had the AoS packs with him (which included education stuff etc).
Oh, one big thing which was good (I should have told Mom this) is that my wife's name in her passport is her maiden name. It is not easy to change the passport name in Spain - and is something we never did. So - she has been doing lots of things in her maiden name here (annoying for me). We were prepared to do the GC in her maiden name but he changed the AoS form to make the case go through under the married name. The only downside is that my wife will have to carry her marriage certificate for travel until she gets off her butt and changes her passport. But that was good.
