First of all, know that Immojeune is a platform for connecting tenants and owners, student residences or real estate agencies. We do not intervene directly in a rental and do not own the property offered.
Hence, the choice of accepting foreign guarantors is made by the owner of the announce. If you see the mention "Garants étrangers" (as shown bellow) on an announce, then they are accepted for this offer.
However, it is not always the case. If you need a french guarantor, you can try getting a private solution such as our partner Garantme or a state/public solution like VISALE or Locapass (which are subjected to social or economical selection processes).
