U can start a buisness here in Qatar by 51 -49 ratio.
first u need a Qatari guy to sponser ur buisness firm.
then u contact an agent or advocate who is providing assistants to register ur company. many agents are here doing this job.
You need
Qrs.200000/-in the bank for commercial registration.
Ur and the Qatari guy's Qatar Id copy.
The agent will make all the necessary documents.
then u and ur Qatari partner together goes to the commercial registration office located at Dafana and u can register the company.(the agent will guide u)
u have to pay the fees(which depends on the activities that u register in ur commercial registration)
then agents fees.
good luck
