I am US citizen by birth. I have lived in Australia my whole life. I became a naturalised citizen so now hold dual citizenship. Ever since I have only ever travelled on my Australian passport.
Early this year on a trip to the US I married my life partner and as such changed my last name.
When returning home I applied for a US passport under my married name.
I am now looking to travel to the US later this year but have a predicament as I have the Australian passport in my maiden name and the US passport in the married name.
The challenge I have is that when booking the flight I have to have the correct name, but this is different for entering/exiting the US.
I can't work out what to do and getting a name change in Australia is complicated as they require documents I don't have, eg my original US birth certificate or even my Australian citizenship certificate (lost in moves).
