Google payements are valid in tunisia on any bank you have account on it you must pay near 20dinars(13$) and wait for about 1month But it works
you don't have citibank in tunisia ??? in morocco it's take less than 2 min for getting money from your adsense check . but citibank exist only in casablanca . so I must travel .
citibank does exist but in capital tunis , so traveling cost near 40$ so i prefer waiting and less charges @hareeshpb : for some countries no
