Dual nationality is not allowed in Pakistan airforce.but squadron leader Usman Nisar is a British national though he has not disclosed his British nationality to authorities and serving in PAF. According to him it doesn't matter if someone is dual national or not, if that's the case why politicians are barred due to their dual nationality? Usman Nisar whole family is in the UK and I one ever asked him anything, he said he fille the form told PAF of his dual nationality but I they are not bothered why should he give up.
If that's the rule in military then it should be same for politicians.
