Federal gov taxing is unfair to the states; should be states choice
Right now, I would call them "diaspora" if they're more dispersed (Armenian diaspora is quite well-known) or a "community", for example "French community" if they're more closely in contact.
If they reject their new land's law and intend to include this land into their old one, they could be "colonizers".
This policy is known as COLONIZATION.
Colonization refers to the action of settling down among foreign indigenous people and establishing control over them. Politically, this action is usually carried out by powerful countries. The Europeans were able to colonize Africa, America and India.
I would say the answer is - D. rain forest
Hope that helps :P<span />
