So I already posted something about this but I rather be on the safe side, hence this post.
Have a valid ESTA which has been approved in January 2020. My dad is Iranian, but I don't have any ties whatsoever - never lived there, never been there, no passport. I want to travel to the USA in September.
However, I don't want the borders to try to get a reason why they should not allow me so I am doubting to get a Non-Immigrant visa as well. Should I get a Non-Immigrant VISA 'just to be sure' or will that be seen as double (as I also have an ESTA) and will they reject me because of that?
EDIT: As I did my research and asked advice, I would like to tell the following. For people who think they are in the same situation as me, I suggest not to take a VISA. They are suitable for an ESTA, so no need to apply for a VISA as well. It can only complicate things and you can only dig yourself into a hole. For my situation, the Dutch law says people who are born after 1 January 1985 with a Dutch mother (suitable for me), are automatically Dutch citizens. Iran doesn't even know that I exist so USA is not likely to care.
