no, u can`t do that. tourist visa is only for 14 days and u can renew for another 14 days. she has to go outside the country while u`re applying for visit visa. if u have all the papers like marriage certificate it can be done by 3 days maximum. just send her to stay in dubai or bahrain for 3 or 4 days, then she can come back with visit visa. hope it will help
