A British national since 1980 and continuing to claim Indian citizenship and use an Indian passport until recently?
The Citizenship Act 1955 wrote:Section 9(1): Any citizen of India who by naturalization, registration or otherwise voluntarily acquires, or has at any time between the 26th January 1950 and the commencement of this Act voluntarily acquired the citizenship of another country shall, upon such acquisition or, as the case may be, such commencement, cease to be a citizen of India.
Are you 18 or over currently? If yes, having registered as a British national when you were under 10 years of age, can you please explain how you managed to retain your Indian citizenship and possess an Indian passport without relinquishing British citizenship when you attained full age (turned 18 )?
When and where were you born? And what was the citizenship of your parents when you were born? Is your mother currently an Indian citizen? If she was an Indian citizen at the time of your birth but is no longer an Indian citizen, when did she renounce Indian citizenship?
The problem that you may face, as I see it, is that you may be accused of falsely claiming to be an Indian citizen all these years and / or forced to pay a hefty fine for using your Indian passport for travel purposes, despite acquiring British citizenship in 1980.
