The deadlines nobody reminds you about
Living in Thailand on a long-stay visa means three clocks running at once, and they are all counted differently. These work out where you stand. No account, and nothing you type leaves your browser.
The 90 day report is an address check. The 180 days on your entry stamp is how long you may stay this time. Tax residency is a third count, over the calendar year. Mixing them up is how people miss a deadline or assume they are fine when they are not.
After the dates: the language. Core Thai is the course for the same people these tools are for. Seventeen lessons free, no card.
