visit visa is 28 days maximum. it doesnt matter if u have relatives here or not as long as there is somebody who will stand as guarantor. a guarantor will provide qatari id, affidavit of support and guarantee letter. thats it, but of course a place to stay... correct me if im wrong but im pretty sure that there were two types of tourist visa here. one,family visit,second.. tourist visit visa..business visa i think doesnt exists anymore. two way air ticket.and visa fee. gudluck!
