How does this work? i have dual Nigerian-British citizenship and i want to travel to the US from Nigeria. if I travel to the US with a british passport ( with ESTA of course) i will need to give the airline details of my UK Passport.
When departing, the airline will need my pp details on checkin and i provide my Nigerian pp details as it wont accept my british pp (saying i will need a visa).
how will the US know that the same person who entered with british pp is the same one departing with a Nigerian one?
