I am an Italian citizen resident in Switzerland with a holiday home in Italy and my British brother wishes to visit next year with his Thai girlfriend (resident in Thailand). He has asked me to fill out a dichiarazione garanzia e/o alloggio, but I am unclear how to complete it: specifically should I provide the holiday home address (I am the owner) even though I am non-resident? Would an attached explanatory letter with details of both my Swiss and Italian addresses be helpful?
Second, my brother told me he's providing the financial guarantee so I will leave those checkboxes empty. Is that acceptable?
Any pointers to a detailed breakdown of the precise meanings of each field would also be helpful.
