Hei and greetings to all.

Basically i am looking for candid advice. I am in Finland with an other schengen country residence permit. I have a child in Finland who is Finnish citizen and we are all living together with the mother of my child, my girlfriend. We are planning to get married but the document from my home country as a bachelor single which can allow us to get married is delayed.
So can i apply residence permit in Finland base on guardian of a Finnish citizen or to wait until i got married and apply base on family ties wife and child?
What are the advantage or possibly of the strongest case to apply? Thanks looking forward to your honest and positive views.
