I'd be wary of deals like this tbh. The minimal residency requirements makes me feel that if they decided to change policy at some stage, before you'd obtained the passport, you'd have no other realistic method of building towards citizenship as you haven't been living there, working there, paying taxes there, don't know the langauge.
Like Americans can move to Netherlands without any hassle using DAFT.
The simplest way is to move to an EU country before the 31st of December and live there.
We are British and we are moving to Finland as soon as the border is open. My wife is Chinese (HK) and will automatically be given residency on the back of me. You can apply for citizenship after 5 years as long as you can show that you've paid your taxes, behaved and can speak Finish.
In return, our kids will get a great education and free university if they choose to go down that path...
Taxes are insane, but having lived in Scandinavia before, you literally get what you pay for, especially if you have a family... in fact, if we didn't have kids, we may well have gone for somewhere in southern Europe, hard to say...
Thing is, after 31st of December, having a resident permit in the Schengen means you will have freedom of movement (travel, not work), after 5 years plus however long it takes to process the passport application, we will have our precious freedom of movement back... more importantly, so will our sons!
But after 31 December, will you be allowed to continue to live in Finland?
