Vietnam visa for longer 3 months

Dear all, what should i do with my Vietnam Visa when I want to live here more than 3 months?
Thank for any help!

Its depends on your purpose. If you want enjoy your vacation then 3 months are enough and by the way any country did not give you visit visa more that 3 months. And if you want to stay in Vietnam for earning purpose then you should find a Job in Vietnam.
