You mixed all together.. it’s not necessary to have a diploma in accounting for visit visa. So either you want to come for a visit, or you want to work here. If you want to come with a visit, I guess you can do it through the Hotel, not sure about your nationality though. If you want to work here, you have to look for a job on the internet or through agencies and come here on working visa. The idea of seeking a visit visa for the purpose of looking for a job here later is not welcomed at all, and called cheating qatari government.
