Seems to me that the Roman immigration policy described here is fairly similar to the old, racist immigration policies that prevailed in the British colonies prior to 1965. Immigration was wide open to residents of culturally and ethnically similar countries. In the US, preserving the foundational ethnic balance was state policy. In Canada, immigration from the British Isles was strongly preferred; the only exception were the Ukrainians brought in to settle the prairies, a measure taken because those lands were empty, no one else wanted them, and the Ukraine was ecologically similar enough to the Canadian prairie that the settlers could make a go of it.
Also seems like in the late imperial period, Roman citizenship was heavily diluted by being extended to foreigners with little if anything in common with Roman society at a cultural or genetic level. With the resulting loss of assabiyah that contributed to the empire's eventual dissolution.
