How can a friend (Bolivian but with Italian ancestry) can get free and risk-free legal advice in London? - italian ancestry

Currently he is in an irregular situation and work under a different identity. I would like to take their ancestors to seek and obtain an Italian passport as soon as possible, it is not his intention to stay illegally and risk deportation. Please help. Thank you!
