Answer: Actual instructions do not consider this possibility, also minister Mantovano in Treviso said the same, this means that going home even for short periods is excluded until proceedings are over to 700.000 people “awaiting for regularization to finally come”.
According to Interior minister, the only chance given to leave and then return to Italy, with a specific Ufficio Territoriale del Governo permission which needs to be written before the exit from Italian territory, concerns entual serious and certificated family matters (such as a relative serious sickness or death); of coarse U.T.G. must receive an application to this certifying health problems, the date od exit and entry..
When the Poilsh woman asked for information she probably was told that she just needs to go to the Italian embassy and ask for an “re-entry visa”. This is a wrong pice of information, in fact there’s a difference between residence paper and the post office receit. This last case doesn’t allow to “re-entry visas”.
She could try to pass as a “turist”, anyway entry-exit stamps would still be a problem and she might lose regularization chance.
At the moment, I cannot guarantee that the lady will be able to go back home and then come back without any surprise according to actual laws. I really hope that “opening” instructions are to come from Minister. I actually recommend to pay attention and be patient.
