Do You Have a Standard or Complex Claim?

Your path to dual nationality depends on your personal circumstances and family history. Many people have a complex claim they don't know about — and Passportia specialises in uncovering exactly those cases.

✅

Standard Claims

Usually straightforward — mainly about documents and evidence

  •  You were born in the UK before 1983 (and your father had no consular connection)
  • Your father was born in the UK before 1983 (and your parents were married)
  • You were born in the UK after 1982 to a British citizen parent or settled resident
  • Your father was granted UK citizenship before your birth and your parents were married

You may already be British

  • British nationals can live and work anywhere in the UK — without a visa
  • A British passport gives you access to 185+ countries visa-free
  • You keep your current nationality — no need to choose
  • You could be British from birth — even without knowing it

What is a Citizenship Report?

For complex claims, we prepare a detailed legal opinion: a thorough examination of your family history, historical documents, and nationality law. If the report is positive, we then guide you through the full application.

Also known as a 'Status Trace', this is the gold-standard assessment for complex ancestry claims.
