The only possible drawback I could see to interracial adoption here in America would be the case of a white couple adopting minority children; they might have more difficulty preparing those children for the realities of living in a country that retains a considerable amount of racism.
That said, I don't think it's insurmountable at all, and I do think that even with that hypothetical issue, the children would be better off in a loving household than a foster-care system which has not only that potential issue, but so many more actual problems.
