Question juridique clé
Whether the cantonal remand judgment was appealable before the Federal Supreme Court.
Solution extraite
No. The remand order was an incidental decision and the appellant showed neither irreparable harm nor a lengthy and costly evidentiary procedure.
Motifs extraits
Because the remand did not finally decide on the residence permit, it was incidental. The federal office could still challenge the final cantonal decision and had procedural standing in later stages, so no irreparable prejudice existed. The additional inquiry into financial means was not long or costly within Art. 93(1)(b) LTF.
