1. As EU national, you are entitled to enter and reside in the UK for a period of up to three months without any formalities other than a valid passport (Article 5.1). You have a continuing right of residence on the basis that you are economically active (employed or self-employed) or otherwise financially self-sufficient in the UK (Article 7.1). You are automatically entitled to permanent residence provided that you have five years of continuous legal residence in the UK (Article 16.1).
2. Under the British rules, you are able to acquire British nationality, but provided that you have a permanent residence card.
3. Under the British Immigration (European Economic Area) Regulations 2006 (as amended), the rules on obtaining permanent residence apply to you and this right is not revoked on obtaining British nationality (Regulation 15).
