- it's definitely more white collar than PAS or Police,many female aspirants list Customs at the top of their preference and there are lots of perks such as land cruiser jeeps and Taluqaat with rich business people but it's a stressful job as most customs officials are regularly blackmailed or investigated by NAB even if they aren't involved in corruption and the lower staff (Appraiser, SPO) are thoroughly criminal minded and financial scandals are a common thing.
