You are probably no longer entitled to Italian Residence
Your EC long-term residence permit may be revoked in the following cases:
- You have acquired it fraudulently.
- An expulsion measure has been adopted against you.
- You no longer fulfil the requirements set for its issue.
- You have been absent from the territory of the European Union for a period of 12 consecutive months.
- You have acquired long-term resident status in another European Union member State
- You have been absent from Italy for a period exceeding 6 years.
I have made two of the points bold, more information on your Italian resident permit would help us answer better or if you have spent 12 consecutive months outside the EU.
