What type of visa is required to start a company in Thailand with Thai family shareholders?

To start the process of creating a Thai-based limited company with your Thai family as majority shareholders, you can initially enter Thailand on a Tourist visa to assist with setting up the company. Once the company is established, your Thai family members can apply for a Work Permit from the Ministry of Labor. Afterward, you can visit a Thai Embassy or Consulate to apply for a Non Immigrant B visa. If you are married to a Thai national, you might also consider applying for a Non Immigrant O visa based on your marriage.
