Starting in 2026 the UK no longer allows British Citizens to get an ETA to enter the UK on an American Passport. They must use their British Passport to enter the UK.

The problem I'm seeing that I can't get a straight answer to is by US law any US citizen must enter and leave the US on a US Passport. So with that being the case how is a dual citizen with two passports meant to fly from the US to the UK?

In the next 3 months I am moving to the UK and have my two passports and I get to keep my job after the move as I work remote. Also not moving to London looking for homes in the north to be close to family.
