Can I obtain a multi-entry 6-month Thai visa back to back or is there a limit to how often I can apply for it?

The ability to obtain a multi-entry 6-month visa (METV) back to back largely depends on the policies of your embassy. They have the authority to set their own regulations regarding the issuance of these visas. However, even if you manage to secure multiple METVs, frequent entries into Thailand may lead to complications, such as being questioned about your stay length and potentially being denied entry after extended periods in the country. Additionally, there are services available that claim to assist with entry issues, typically at a fee.
