Migration significantly affects both the country of origin, and the destination. In host countries (destination) , it may lead to economic growth by filling labor shortages and contributing to cultural diversity. However, it may also strain public services and a tense social environment. In the country of origin, migration can result in brain drain (a large amount of  emigration or migration of individuals out of a country) but can also boost the economy through remittances for their familys members. Migrants usually face challenges when adjusting to their new engironment as they have to, basically, start a new life.
