To return to your home country prepare to close down your Los Angeles household
as previously discussed in "Departure/Before
you leave" section.
Also prepare your goods to go through customs by making a detailed inventory
and secure a proof of change of residence so you may go through customs easier.
To have the lowest taxes you will need to have had a residence abroad for
more then 12 months and have had use of the possessions in a private capacity
for at least 6 months.
