Is there a guideline how much time can one take for moving after getting a green card? Should one count days during the first year to not run into problems or is this more second year and onwards?

There does not seem to be much information about this besides very vague statements.

Do you mean getting an immigrant/green card at a U.S. Consulate abroad?

I mean after the initial entry when they stamp the immigrant visa and send you a green card. Is it alright to take 6 to 9 months to getting everything in order in your origin country and getting settled in the US? At some point they will probably start asking questions about why the long absence or are you actually living here etc. Any guidance on how long this actually is or how to mitigate these risks would be helpful.

Yes, that would be fine but you probably would want to apply for a reentry permit when you are in the U.S. to protect your green card in the event you are outside the U.S. longer than expected.
