This communication will analyse the role played by social networks on Syrian refugees' border crossings and coping strategies to/in Jordan since 2011. It will focus on the evolution of ties Syrian refugees relied on to leave Syria, enter in Jordan and leave refugee camps to settle in local communities. After an "open-door" policy towards Syrians, the growing flow of refugees has lead the Jordanian government to implement restrictions to the entry and stay of this population in the country. While transnational networks were playing a key role at the beginning of their arrival in Jordan, refugees now rely on weaker ties and became more dependent on professional actors of migration management as well as informal ones (e.g. smugglers), which has deep impact both in terms of coping strategies and migratory itineraries. Understanding the dynamics of these circulations should also help to understand the ongoing flows from Middle East to Europe.
