German to English Social Sciences History

In a letter, dated in July of 1939 and written by a Jewish refugee from Vienna, then staying in Menton-Garavan, France, the writer talks about spending some time in Nice, France, where she had to go to various offices on a daily basis, followed by:

"Endlich erhielten wir das Rezepisse für 3 Monate und da hatten wir Glück, dass es für die ganze Riviera ausgestellt wurde, sonst hätten wir mit unseren Lieben nicht beisammen bleiben können. Es werden nämlich nur bestimmte Orte zugewiesen, es ist auch kein Wunder, weil soviele hier sind!!”

Every reference I can find defines "Rezepisse" as a "receipt" or "acknowledgment of receipt," but this doesn't seem to fit this context. It is obviously some sort of document that was issued, which was apparently valid for 3 months. Perhaps just a "temporary visa" or "residence permit" of some kind?
