I'm a student currently living in S. Korea and I have double nationality: Dominican and German. I want to travel back to my country but through Europe is much more expensive than laying over in the US. However, I don't have VISA for the US in any of both passports. I would like to layover in the US with the German passport since I can only do an ESTA form and it seems easier and quicker.
However, I want to be sure that I can travel as follows: Going out of Korea with my Dominican passport, entering/exiting the US with my German passport with ESTA form and entering my country with my Dominican passport. And if so, should I book my airplane ticket with my Dominican passport information? (Since it's the final destination).
