Are people generally happy or unhappy once they immigrate to the united states?

Well, it generally depends on where they came from. If the country that they were in before, treated them poorly with disrespect, they will be happy of course. But let's say they come from Canada.. Canada has free health care and they might not like that the United States doesn't. It all just depends on the perspective of the person and where they have came from.

Hope this helps. 

Ibeileve it will be c. : )
