Do Indian passport holders need a visa to travel to Bangkok?

@Ivan ******

Well, even before the current ผ.60-ม.17 60-day Visa Exemption with the former ผ.30 30-day Visa Exemption, certain nationalities (e.g. India) were unable to obtain a 30-day Tourist Extension at any Thai Immigration Office; or, some Thai Immigration Offices just refuse to give a 30-day Tourist Extension as each of the individual local (nearly 80) Thai Immigration Offices across Thailand do have individual discretion for additional requirements or operating policies besides central-level policies....

in your particular circumstances, it is a possibility that this particular Thai Immigration Office:

either wants you to obtain a 1-Year Extension based on having a Thai Wife or 60-day Extension based on Visiting Thai Family, both of which do have additional requirements (e.g. minimum proof of funds) beyond those for a 30-Day Tourist Extension

As you have already made entry on a 60-Day Visa Exemption for Tourists, but this Thai Immigration Office may determine that your purpose of stay is not tourism and not want to issue an Extension for Tourists, but more open to issuing an Extension for someone with a Thai Wife.....
