Three benefits:

More cultural exchange, in many forms: cuisine, religion, philosophy, idelogy.Higher ethnic diversity: many scientists agree in that genetically diverse populations are better suited for survival than less genetically diverse population.The development of a more tolerant culture, because of the constant contact of peoples of different origins.

More conflictivity can arise, because people of different backgrounds do not always get along well.Social bonds and trust can be eroded, for the same reason as above.Local cultures can become overriden by the blending of new incoming cultures.
