Help about my rights as a mother of an italian child

Hi Laylat,

Welcome to the Forum; I'm not sure what the answer to your question is.  Most international laws regarding citizenship are based on the principal of "ju sanguinis", which basically means that citizenship is inherited from your ancestor (parent), so if anything your child is an Italian (which has been recognised by the issue of an Italian passport), who also has the right to Tanzanian citizenship (from yourself); the child's citizenship status does not influence your nationality.

However, I've just read the British Government Website and it would appear that under EU law, that as long as you're working, or self-sufficient (no social security), or a student, that because you're from outside the European Economic Area (EEA) and you're the family member of an EEA national (your child) you have the right to apply for a UK residence card.  There are more details on the UK Gov website; follow this link.

So, what I think the answer to your question is, you will remain a Tanzanian, but with the right to live in the UK for 5 years, after which you can apply for a permanent residence card.

My advice is to follow the process described in that link above and see how you get on.

One word of warning; this is based on the current law; you are probably aware of the current Brexit debates and there is no guarantee what the situation will be, 5 years after you get your initial residence card.

Hope this helps.
