Depends on your starting location.

What country are you in,

There are 37 nations that are not required to have a visa for a tourist visit. ( to visit family)

Visa Waiver Program (VWP) (http://travel.state.gov/visa/temp/without/without_1990.html)

If it is not free, merely a touriest visa would be @ 160 to 225 dollars,
The higher cost visas are adoption, work and immigration visas
