Dear Amir Amir,
Thank you for reaching out to the Wefugees community.
Marriage in Italy was already a topic on this platform before. You may want to check, for example, this thread for more information.
To understand your situation better, it might be helpful if you could provide some more details. Are you still in the Asylum procedure or do you have a residence permit? I assume that it will also be essential that you can show documents as a valid passport and a certificate of no-impediment.
Please feel free to get back to us with any further questions.
All the best,
