What 3 benefits do I get with an O-2 work visa? You can do…

How long is the O-3 visa valid?

Because the O-3 visa is a dependents visa, you must stay with the principal visa holder, which is either the O-1 or O-2 visa holder. Because O-1 and O-2 visas are initially issued for three years, your O-3 visa will be valid for three years as well.
