Form S1 — Housing Statement for Minors
Plain English
It's the housing-suitability statement used in family reunification cases for minors. It declares that the home meets minimum standards for the number of family members who will live there.
Why it matters
Without the right S1 (or local equivalent), the family nulla osta application can\'t be processed. The comune\'s technical office typically issues or attaches it.
Common confusion
Some comuni issue an idoneità alloggiativa certificate instead. Both serve the same purpose. Ask your comune which form they use locally.
