I'm currently 23, my SO (significant other. We're not legally married) is 24, and we have a 3yr old girl, and twin 18mth old boys together. (with all kids we are both the biological parents. None of them are from previous relationships)
We are wanting to move to Finland sometime in the next year. Hopefully by no later than April 2015. What I'm wanting to know is:
-Would it be best to apply for a citizenship now, or wait until closer to the time we're wanting to be there by? I know that I, and my children, would want to stay there permanently, but my SO is a little more hesitant. (He actually has family he can tolerate & would miss here in the states) And how high a chance is it that our citizenship request would be denied? Does anyone know why they would deny us?
-What exactly do they test cars on, before they're allowed to be imported to Finland? He has an '80 el Camino he wants to bring, but he's not sure what is required, and I can't find anything specific, only that they do have to pass certain tests.
-What is the average job pay there, and how hard is it to find work? Is there a minimum wage, like in the states? (It's $7.25/hr here) Would I be able to secure a job before moving, or would I have to be jobless for awhile once getting there, and hope for the best in finding one? If I would be able to get one before, how would I go about looking?
-What is living there like, in general? I live in Nashville, TN, so I'm hoping it's a bit more quiet.

-How expensive are vehicles, and what would be the best (long and short term cost wise) car to own there? I have an '88 Acura Legend LS now, that I love, but I'm not sure it would pass the requirements to bring it there. So we'd probably have to buy a family vehicle upon arriving.
-What is the housing like? What I mean is, I know there's bad neighborhoods/houses everywhere, but is there a lot of ghetto? (Terrible/cheaply made/falling apart/not taken care of houses, violent crime, drugs, etc) Would it be best to find a good real estate agent and get a place before, or stay in a hotel once we get there and search for a place? (I would prefer to have it all taken care of upon arrival, but IDK if that would be the best option)
-How expensive is child care? With 3 small children, that is definitely important.

Well... I think that's it. I had a list somewhere that I had written my questions on, but I seem to have lost it. I think I covered everything, though. Thank you in advance for your help!
