My children are holding dual citizenship - Mexico and Austria. We are currently in Mexico and will travel back to Austria with a flight from Mexico City to Miami and from there to Schengen (Madrid) with final stop Vienna. My children entered Mexico with their Mexican passport, as this is required by law. I'm currently wondering how to correctly travel through the USA, since they don't have a US visa for their Mexican passport, but can travel with ESTA only using their Austrian passport. They will obviously show their Mexican passport on leaving Mexico. But with what passport should they do the check-in to the flight? I want to use the Austrian one, since ESTA. But won't the airline/mexican migration check check for the migration stamp? Will the US migration deny them entry based on this situation? I could not find information for this situation online, since everything is centered around having dual citizenship between US and another country. Unfortunately the consulate and embassy hotline only guide me to their respective web pages.
