Assuming you are talking about Asian/Hispanic experience during Jim Crow/Segregation prior to and during the African American Civil Rights movement:

What was life like for Hispanics/Latinos in pre-Civil Rights Act America? Did they suffer the same types of discrimination as African-Americans? written by u/Nevada_Lawyer

Where did the Asians sit on the bus during the US segregation? written by u/EdHistory101. It talks briefly about hispanic experience too.

How were non-black minorities treated in the Jim Crow South? written by u/Dubstripsquads

If an Asian-American went to a diner in the Jim Crow South, where would they be seated? written by u/Dubstripsquads

It's 1935, I'm Mexican and I walk into a segregated Southern diner. Do I sit on the black side, or the white side? written by u/Kugelfang52 talks about the Japanese Experience

Where did the Asians sit on the bus during the US segregation? written by u/EdHistory101 provides an excellent synthesis and lack of logic behind segregation. Additionally two other top level comments link to other threads (most of which I already linked here)
