I don’t know where else to ask this but I am out. My Latina fiancee has been getting derogatory remarks in public. I’m done. We are both hard-working manufacturers and we are looking at Spain since she is already fluent in Spanish and I am actively learning.
You may wish to take the passport with you, maybe eventually things will change in US, or you will need to reference your citizenship. For instance UK home office refused to change my name without having it changed in my other passport first. Even ongoing travel restrictions to the country involved did not make them vaiver.
So from that perspective it might be useful for you to have the US passport. I have now accepted that every 10 years I gotta pay my birth country tax… In cash… And spend at least 1 day trip to the embassy to get the process started again. Even if I completely disagree with their politics.
