Pop job appropriation?

[slackerpants]

I noticed that after I conquered a planet, my founder species pops would move in and grab the best job positions, leaving the previous rulers and eventually specialists unemployed for a while. I thought this behavior was awesome mainly for rp reasons, but it could also allow me to gene tailor pops and let them just get the appropriate strata somewhat automated (since pops normally otherwise don't leave their jobs).

However, I don't understand the triggers for this. I think it's based on setting citizenship to residence, but it seems this still leaves some jobs open for grabs for aliens, like for example merchant ruler jobs, or colonist specialists. Can anyone confirm this or tell me the exact triggers for this behavior?

Edit: I'm playing on 2.2.2

I'm not sure if this answers the question you're asking, but there is a policy setting that sets land appropriate to allowed or not.

I don't know how it decides how many or which populations are moved, or when some of them move to.

Yeah this is not it. This continues so that whenever a new pop is created, either by normal growth, immigration or resettlement it will take the best job possible, and demote non-citizens if need be it seems. Seems to work with or without that policy.
