Thank you all, guys! Excited to see your reply and information.
I phoned the Immigration Service using the number given by @Rip (thanks) and I was told that I would be able to apply with my husband using the application form OLE_PH1 and be processed simultaneously, although this form is intended for someone whose spouse has already had a residence permit. I would probably just fill in as much information as I could in that form and try my luck.
What I am worried at the moment is that, we are foreigners living in the UK and our UK residence permit would be curtailed to 60 days as soon as my husband resigns from his current job. We are planning to apply for the Finnish RP in the UK but not sure if our RP would be granted all together. If he is granted the RP first and moves to Finland, I would be not eligible to stay in the UK.
My question would be: will our RP would be granted at the same time? does anyone have any idea about the total processing time? I read the average processing time in 2011, but there is no specific information regarding my case.
As a background information, my husband got a job offer from a large Finnish company as special expert. We are foreigners living in the UK.
Thank you. Any help is very much appreciated!
