Yes, most long-term U.S. visas allow you to bring your spouse and unmarried children under 21 as dependents.

They will need to apply for a “dependent visa” that matches your visa type (e.g., H-4 for H-1B, F-2 for F-1, L-2 for L-1).

Children on dependent visas can go to school in the U.S., but they usually can't work.
