I am planning to travel to America at some point within the next 1 or 2 years on an ESTA. I was born in the UK to a British mother and an Iranian father. I have only ever held a British passport and have never set foot inside Iran.
My main concern is how having an Iranian father could affect my entry into America as the last thing I want is a wasted trip that ends with me getting denied entry and put on the next flight back to the UK.
I also have a first name that is of Iranian (but not Islamic) origin. My second name is English.
Does having an Iranian father make me ineligible for an ESTA meaning I would need to apply for a visa? Or does it make me completely ineligible for entry into America?
