Hello @williams
Welcome to the Wefugees community and thank you for your question.
To me it sounds very likely that you will face a Dublin procedure. German or Belgium authorities won't accept your application for asylum because you have entered Europe in Italy. You can apply for asylum there.
Regardind your wife:
If she already had an asylum procedure in Belgium she won't be deported within EU in accordance with Dublin III. She can't have a second procedure in another country anyway. In addition, she might get deported back to her home country. The only option would be to appeal against the decision of Belgian authorities.
Best regards,
Thorgen
