Hi,
I am a dual UK and US citizen. However, I didn't renew my British passport (born in UK in 1973) after 2012. I am planning to visit UK with US passport. I was trying to get ETA. The system asked to identify any other citizenship I have/had. The system has 4 different options for British citizens like British overseas resident, British overseas something (each having a 3 letter code GB and then something). None of these seem to apply for a regular British citizen. My passport code is GBR but none of the 4 options has that code. I tried calling British embassy phone but not being able to talk to a live person. Can anyone help me?
Thanks.
