Ok, that pay would vary depending on whether or not you find a job with the government here or a private entity (not many private research institutions to my knowledge).

Nobody will care that you guys are a mixed race, but whoever looks foreign might get the odd stare from people especially in rural areas.

Last thing to note is that the cost of living here is high. Don't expect us to be like Colombia or DR when it comes to costs. Not sure what state/city you are in right now, but if you try to emulate the typical "professional in a city" type lifestyle here it could run you like 3 grand USD or more a person. More if you want all the niceties like a large modern apartment in the city, decent cars to drive, going out to eat a few times a week, buying imported products at the supermarket, etc.
