Does a non-O visa extension change my 90-day reporting date in Thailand?

If you've recently extended your NON-O visa for your Thai wife, your 90-day reporting requirement will still be based on your previous reporting date. Unless the immigration office issued a new report slip when you extended your visa, confirming a new reporting date, you should continue to report 90 days from your last report. In most cases, you'll receive an email reminder for the upcoming report.
