Embassy of Canada told me that they would still not issue extension letters, but also that they are not needed when applying for any long-term visas within the country. This does seem to render the 30 day extension inapplicable, for my case.
Combined with today's announcement of a 9 month visa for foreigners that is said to start next month, what are my best options for remaining in the country at this point?
TLDR : Answer Summary
The user is confused about their visa situation in Thailand after the Canadian Embassy stated that extension letters are not needed for long-term visas, leading them to believe a 30-day extension is unnecessary. They mention an upcoming 9-month visa but are unsure how it applies to their current situation. Comments clarify that the new visa is not available in Thailand and that the user needed to apply for a long-term visa earlier.
