Yes, dependents can study in the USA on a dependent visa. Dependent individuals are eligible to study at U.S. institutions through a dependent visa although different regulations apply. F-2 dependents (spouses and children of F-1 students) can study in the U.S., but they are typically restricted to part-time study unless they change their status to F-1. The U.S. allows L-2 and H-4 dependent visa holders to pursue full-time education without any limitations. The opportunity to study while holding a dependent visa exists although each visa category comes with its own rules.
