How can I obtain a sticker visa for Thailand while currently in Vietnam?

@Blaze ********

I assume you want to apply for a tourist visa. (1) Check Thai embassy Hanoi website link visa category page and pay attention to the number 7. (2) Write an email to the embassy to clarify if Indian passport holders are eligible to apply for Thai visa outside India as it said certain nationalities are required to apply from home country. (3) If your on tourist visa for Vietnam, make sure its valid before you apply for another country visa. (4) Once the embassy confirms Indian passport holders can apply for Thai visa outside India, just go there and submit all the documents shown on the link. Hope it helps.
