I am Algerian citizens living in the UK since a while now but unfortunatly I can't see my daughter who is 5 years and she is Italian citizen with her mum who is italian too.

because I am still waiting since 3 years to be granted my Indefinite leave to remain in UK ( Mybe positive mybe negative) by the Home Office.

My question is: If I want to apply to join to settle with my daughter in Italy what are my chance ( Please bear in mind me and her mum we are not together and we are not going to get married ) ???????.

Considering your situation and the current political climate in Italy with regard to immigrants, I would suggest you get your papers from the UK first. Be careful though, because although you may be given permission to reside permanently in the UK, this may not give you the right to reside in Italy, or travel without a visa. Check with the Italian Embassy in London first.
