It is always complicated for young foreigners to settle in a relatively short time in a big city. Among the biggest challenges are bureaucratic challenges, lack of housing, work, social integration, and peer-meeting opportunities, which demotivate people and force them to leave big cities. Handshake will boost social inclusion in metropolitan cities by developing an online app, offline events and a social inclusion guide for big cities – Paris, Milan and Brussels. Other major cities may be included in the future, when the project reaches the expected results.
