Foreign students have the right, as do all students, to housing assistance. The only additional document to provide will be their residence permit, valid for more than four months and valid for the current academic year. This measure is applicable to all foreign nationals, including those originating in the EEC.
Specifically: Don't wait to receive your residence permit before finally returning your ALS or APL file (it may take more than three months to receive it!): return your incomplete file to the CAF. You can send a copy of the residence card as soon as you receive it.
