Boyfriend going to meet my parents for the first time SO NERVOUS!!!

Ok my boyfriend has met them in passing like saying hi and bye etc but I want him to meet them but when is it "right" for him to meet my parents? We have been together for awhile now I just feel like I want to make sure everything is perfect And that they'll like him.... ***opinions but be kind please*** &- It's a biracial relationship which my parents don't care about stuff like that.... how should I go about bringing it up to my mom? I love him and trust him with my entire soul ❤
