There's nothing like starting digits for visas. I guess you are talking about buying them. If yes, buying & selling visas are illegal as per Qatar's law.

FYI.

1. Qatar allows Business visa maximum duration is 3 months not extendable anymore, cannot get employed under this visa.

2. Tourist visa (arranged by qatar airways & or jointly with a hotel), Maximum period of stay is 30 days.

3. Resident permit/visa - Allowed to work once you pass the medical examination & visa is extendable as long as your employer needs you. Presently this visas are on hold for india & certain nationalities. This visas are very difficult to obtain unless you got recruited by a company and your visa is approved by qatar immigration.

Hope it helps, wait for other QLer's to respond too...
