41 CFR § 302-8.203 - What is the authorized time period for extended storage of my HHG?
Time limitations for extended storage of your HHG will be determined by your agency as follows:
(a) For the duration of the OCONUS assignment plus 30 days prior to the time the tour begins and plus 60 days after the tour is completed;
(b) Extensions may be allowed for subsequent service or tours of duty at the same or other overseas stations if you continue to be eligible as set forth in § 302-8.200; and
(c) When eligibility ceases, storage at Government expense may continue until the beginning of the second month after the month in which your tour at the official station OCONUS terminates, unless to avoid inequity your agency extends the period.
