2% of Americans identify as partly or entirely American Indian. That means that like you, 98% of the rest of us have an ethnic heritage as immigrants to the US.

We, or our ancestors, were able to assimilate into the US because enough of our society was accepting of people from other cultures, with other social norms, other perspectives, other histories, etc. We're basically all from some other country.

You need to clearly separate ethnicity (cuisine, preferred language) from technical approaches to engineering. In doing so, the way you work with any engineer will be the same, no matter their ethnicity. After all, you'd like them to afford you the same professionalism.
