Its a misperception that 3000 $ is nothing. Its is more than enough since accomodation is free, education and health is free and u dont pay taxes. A quality jeans shirt cost 30 Euro in EU and 3000 Rs in Pak. So, 3000 is alot.

Family moves with a diplomat in whichever country he is posted but in PAS, many officers serve at 1 station while family stays at a different city so there are more hassles.

2ndly how can one manage legally in 45,000 Rs in PAS in Pak? In summer electricity bills cost minimum 15000.

The education of kids is disturbed after every 3 years in FSP but in PAS, you get posted from one station to another even after 6 months, hence therez more disturbance for kids.
