Yes, you can bring your family members to the USA with the work visa. If you have a work visa, your spouse and kids under 21 can apply for a dependent visa that goes along with it (like an H-4 visa if you have an H-1B). Dependents can live, study, and get healthcare in the U.S. But not all visa types let spouses work; for example, only L-2 visas for L-1 holders and H-4 visas with work permits for H-1B holders allow that.
