Well I remember reading a couple of sources on the DR having about 1 million legal and illegal haitians. Here's one I found with a quick google search:
"There are no reliable figures on the number of Haitians and Dominico-Haitians currently living in the Dominican Republic, and the question is a controversial one.5 The Inter-American Commission, citing Dominican migration authorities, reported in 1999 that approximately 500,000 to 700,000 ethnic Haitians were living in the Dominican Republic.6 Other figures range even higher: "a million or so," was the Dominican Army chief's best guess."

"Illegal People":
This was in 99'...and if that 5 to 7 figure was accurate, i'd say that might be about right. With that said, this is what we have so far (according to ppl on this board):
Haitians: 500,000 to 1M
Koreans: 500 (any source?)
Chinese: 30,000 (I need to confirm this, I think I got that from the following site:
Barrio Chino Santo Domingo );
it may be less since I think that includes Taiwanese (whether this is a sep catagory is a political issue) and Koreans.
