If you just started with the 3rd daycare and you feel comfortable with having your daughter there (all her needs meet, taken care off, attention and so on) then I would give it a week or two and see if your daughter has adjusted. A child any age needs time to adjust, give it time and having interaction with a different ethnicity is a great thing and encourage it so she gets use to others.
My daughter is 4 years old and even though both sides of the family are all caucasian she interacts weekly and almost daily with other ethnicity and it is amazing how she recognizes different facial features or color of skin but that is it, we are all Americans. We never make a big deal about different ethnicity (which kids can pick up if you point it out, even read your level of comfort around others, talk about it a lot when out and about or at home) and she loves, talks, and enjoys being around everyone. So do not keep her away from others just because it makes her upset or cry, she will learn to be comfortable around others.
