Why irregular migrants arrive and remain: the role of intermediaries

Despite many efforts to combat irregular immigration, there is a widespread perception of a failure of public policies in this field. But because unauthorised immigrants are officially excluded from formal labour markets, housing markets and most welfare provisions, they can settle if they find other sources of work, income, housing, and social protection. In this regard, a crucial role is played by various intermediaries: people or institutions who favour the entrance of immigrants, their entry into the labour market, accommodation, response to their social needs, and possibly regularisation. They can act for profit, but also for moral reasons. They can break the laws and work in the shadows, but they can also work in legal forms. In this article, I will explore the identities of these intermediaries and their practices of support towards irregular migrants. My purpose is to show (1) what precisely constitutes intermediation, in what activities it can be factored, and what the main categories of intermediaries are; (2) that the implementation of migration policies is hindered not only by migrants' practices to circumvent controls but also by the action of these intermediaries. For this reason, too, it is so difficult to eradicate.
