Hi, I arrived in Thailand with an STV early April. Do I need to file my 90 days report for my initial 90 days yet or do I have to wait till I’m here for 90 days and then file it?
TLDR : Answer Summary
You should file your 90-day report between 15 days before your 90-day stay ends and up to 7 days after that period. If you're applying for a visa extension, consult your local immigration office about the timing of your report.
