The new organisational structure of the Department of Home Affairs was approved in 2008. There were 56 immigrations officers, two chief immigration officers and two assistant directors were recruited in 2008. The approved posts are 142 and only 75 have been filled. The vacancy rate is high because some officials have resigned or were promoted. Two immigration officers were dismissed for fraud, with regards to amending sick leave periods and unauthorized leave. There are presently no corruption cases at the airport with regards to the Department of Home Affairs.
