Hello Siv.
I hope you have better luck than we had. Our application shouldn't have been rejected as no evidence is needed for first 90 days, but it still was.
About the initial application: we made it 2nd of Dec and got reply right after christmas.
We showed bank statements for roughly 30k USD, and I couldn't show any evidence of employment in Finland because I just came back after spending two years in Australia.
Maybe being unemployed at that moment made me look undesirable person.
After we had got the decision overturned we ran into more difficulties.
My wife had to leave Schengen 2nd of March and it simply was impossible to get passport sent back to us in time, so we sent it to UK embassy in Finland who sent it to Stockholm and we took a ferry to Stockholm and picked it up from there 2nd of March morning and flew to London in the afternoon.
That was a close shave.
I sent email to border guard office in Finland what would be the consequences for overstaying in Schengen for couple of days, I still haven't got an answer.
Since we came to UK we both got job within two weeks and we applied residence card which came 3 months after the application, no hassles with it.
Good luck with your application and hope you don't need to go through same trouble than we did.
