Miami, though it is a “diverse” area as you say, doesn’t mean it is Asian-friendly. You are equating the presence of non-white people with an assumption that Asian Americans and Asians are accepted there. I’ve been to Miami several times and have found in my personal experience (I am a third-generation “assimilated” Asian American with no accent – in case you are wondering) that there is a lot of racial animosity towards Asians. People of every color can be racist.
