I am from bangladesh. I was living in bangladesh and was in relationship with finnish citizen. We never lived together at all. Then we decided to live together in finland. So I applied for visa. For my visa application, I had to show bank statement for last six months. I was not exempt for this thing cuz tat time i was not married with finnish citizen. so normal law applied. In my visa application form, I mentioned that purpose of visit is to get married in finland and apply for residence permit. They gave me 14 days time. After 14 days, i got visa. So i came to finland. I was started living in shared room because my girlfriend was living with her family. Well we started to look for apartment and after 1 month, we found one. My girlfriend made rental contract on her name and we moved in. After that we went to maistraatti and get married. (simplest and normal one, with no witnesses). after that i asked maistraatti that i want to register my address as im gonna apply for residence permit and i want to show in residence permit application form that we are living together. They replied that they cannot register me and right process is that first i have to apply for residence permit and then i should come to them again with receipt that ive paid for residence permit then they can register me and i can put in application form that i am living with my finnish wife and police can see it in their computer records too after i will be registered. so i did the same. I applied for residence permit on the basis of family ties and entered in form my address and i told the person who took my application that im gonna register in maistratti tomorrow with the address i mentioned. So next day i went to maistraatti with reciept and they registered me, but registration was temporary and they said that once i will receive residence permit, i have to come again and change to permanent. so i took extract of mine and my wife's with the same living address and went to police again and submitted em. that was the whole process. on my reciept (paper given by police when i applied for residence permit) it was mentioned that estimated processing time is 4 months.
I called every month and get always same answer that application is in processing. The exact date when 4 months completed, it was sunday. so on monday, i called police and this time they said that they already ordered my residence permit card and i will receive in about one and a half week. i was very surprised and i almost 3 times asked the officer that really decision has been made, and it was approved etc etc and he said that yes you got permit. and normally it takes 2 to 3 weeks for making of card but we already ordered your card about week ago so you will receive it in one and a half week.
and then after 2 weeks i received my card

I was very nervous because of many many posts on this forums. I was from backward country, i never lived together with my wife, and during those 4 months waiting time, 2 times my wife had to go to Social office for benifit cuz we newly moved and there was financial problem. But yet i got my permit.
So this was my experience and according to this, and according to my experience, i found out that when everything is according to law and in documentation, there was no reason of rejection, the decision was positive.
