Just an oddity - today I got an email from Immigration telling me my 90 day report was due. Mr K didn't get one and I did it online for both of us, I think I did his first. The only difference is that he is the main visa holder and I am on spouse Non-O.
Anyway, nice to get a reminder BUT we've just come back from overseas and don't need it, so obviously the 90 day report section of immigration doesn't get up to date info on people going out/into the country.
It really wouldn't be so hard to link the data, but hey - what do I know.
