What if the race of the planet is too strange to blend in?

Wait a while, maybe it will be civilized after a while, or it can be purified/enslaved directly.

If you don't enslave or purify the planet, you will be paid for computers with immigration policies. If you can't cross his home, the planet will be occupied by uncivilized races, and uncivilized races will not work, which will successfully consume the national strength of computers.

There are many races in the interstellar stellaris game, among which there are variation subspecies after the variation of the original race.
