Given that you are out of the country at the time of your visa's expiry, your husband has to pay an additional charge to enable him to renew your visa,which was Qrs 500/= before. Since it has expired only recently, there is a grace period of 1 month with no penalty, but the question is why did he have to cancel your visa when you could have returned to Doha before it expired... such issues would have been avoided if you were here before your visa expired.
