Thank you.

To apply for reagrupación familiar in Barcelona, it appears that I need to provide "documentación acreditativa de disponer de vivienda adecuada."

As I understand it, I apply for this document at the ayuntamiento. Do you know if in practice they conduct an actual home visit or do they do they only do a home visit in some cases? I don't have much time to get the document and I am briefly out of Spain. If they do a personal visit in every case, then I would have to be present, correct?
