Key legal question
Whether the public-law appeal was admissible despite Art. 83 lit. c ch. 2 LTF
Extracted holding
The appellants failed to plausibly show a legal entitlement to a residence permit, so the public-law appeal was barred.
Extracted reasoning
For foreign-law residence matters and related procedural incidents such as suspensive effect, admissibility requires at least a plausible entitlement under federal or international law; the appellants did not establish one.
