Adult migrants in all OECD countries are a diverse group, with different profiles and levels of education. Even if they hold tertiary degrees, they are more likely to have poorer labour market outcomes, including lower earnings. Participation in the labour market is more difficult for foreign-born adults who arrived at a later age and acquired their qualifications in another country. It is important that host countries design and implement policies that will help immigrants improve their chances in their labour market, benefitting both the person and the country.
