Hello TuyetDang and welcome to Expat.com

So as to better understand the type of visas for Vietnam, I invite you to read our section Visas for Vietnam.

Hi thank you for your info. I have had a look at the visa section but was wanting to know if I go onto a tourist visa and search for a job within that 3 month of stay on the tourist visa can I change my visa to a business visa if i successfully find a job? As I am planning on staying for at least 2-3 years in vietnam.

Get a job and the school will take you through the paperwork as you will need a work contract to get the work visa.  Be sure to have all the needed docuemnts from home stamped/authenticated as needed before you arrive in VN.  It makes the process easier.
