Which passport should I use to apply for a DTV as a dual Canadian-Mexican citizen?

As a dual citizen of Canada and Mexico planning to apply for a DTV (Thai Visa) from Mexico City, it's advisable to use your Canadian passport. Given that your financial matters are closely tied to Canada and considering the general perspective that applications from more stable countries may benefit the process, opting for your Canadian passport could enhance credibility. Furthermore, it is suggested to consider which passport is most frequently used for travel, as that may influence the DTV issuance as well.
