What Visa Should My Mother-in-Law Apply for if She Moves to Thailand with Me on a Tutor's Visa?

The original poster is moving to Chiang Mai with a tutor's visa and inquired about the appropriate visa for their mother-in-law, who wishes to live with them. Community members clarified that there is no 'tutor visa' per se, and the mother-in-law cannot extend a visa through a family relationship with an in-law. Suggested options included the Non Immigrant O visa for those over 50, as well as other unspecified methods for obtaining a visa based on family or other qualifications. However, the final guidance was to check the relevant Thai Embassy or Consulate for specific requirements.
