- 4. Non-command sponsored dependent (Cat-V), not residing at the sponsor's overseas location, may travel Space-A unaccompanied to and from the sponsor's overseas location with a letter from the installation commander. There is no limit to the number of times you can travel during the year. Except for to Korea. Non-command sponsored dependents traveling to Korea are authorized one 30-day visit per 365-day period. Extensions are not authorized.
