I truly hope that one of you has been in a similar situation and will be able to provide some advice and/or guidance. I am about to change my RP grounds from working as a scientific researcher to family ties (spouse is a Finnish citizen).
I’ll provide here some back story which I hope explains why I am extremely stressed about this RP ground change. I am a non-EU citizen that moved to Helsinki in August 2015 to pursue my Master’s Degree. Since then I have been residing in Helsinki on RP and extending it when necessary. My current RP has just been issued and it expires in August 2021.
In 2017, I met my, back then-boyfriend, and currently fiancé. We have been living in the same apartment since August 2017 and got engaged in January 2020. Originally, we thought that I will just extend my RP based on scientific work (as I did already), have a small wedding party in Italy in September, then get married in the Helsinki Maistraatti, so that we will have enough time to deal with bureaucracy before it is time to re-apply for next extension.
Unfortunately, the COVID outbreak changed our plans and we had to push the booked villa and the ceremony for one year (September 2021). And that’s when the problem arises. When do I need to apply for an extension of RP on new grounds (family ties) to make sure I receive it before September so that I will be able to attend my wedding party in Italy? Since we already moved it once due to corona and lost some money, I am dreading the scenario where we have to do it again.

Also, when you apply for an extension on the new grounds (family ties), which application should you fill? I saw on the Migri website an application for family ties (spouse is a Finnish citizen) that assumes that you are not in Finland. Also, the extended application on the family ties asks for the proof of finances, which is a bit confusing to me. So, you do not need to have enough money to support yourself when you apply for the first time but then you have to show them during extension? As a researcher, I largely depend on the grants and even though I have the funding till December 2021, I am not sure I will receive any new grant decisions before September 2021, so I am not sure I can prove sufficient means for Migri should we apply e.g. in April.
Are there any couples out there who had the same situation and can share their experiences and provide some advice? It will be much appreciated.
