Entering Thailand on a visa issued in one passport while using another can indeed lead to complications at immigration. If you've applied for a Destination Thailand Visa (DTV) with your Philippine passport and now/soon hold a British passport, it's advisable to carry both documents. When you enter Thailand, you should present the DTV along with your Philippine passport, even if you're traveling on your new British passport. This ensures that your visa status is clear to immigration officers. However, for peace of mind and to avoid any potential issues, consider informing the Royal Thai Embassy about your change in citizenship. They might offer solutions like transferring the visa to your British passport or suggest reapplying. Always having your travel documents in order and aligned with your current citizenship status is crucial to ensure a smooth entry.

There is one in the group posted recently who got DTV visa from PH
