Do I need to do a 90-day report while waiting for my Non-O visa extension approval in Thailand?

@Robin ******

your application got accepted, and you were given a stamp or a paper notice "application under consideration, visit Immigration on September 29" for which you need to check your passport. . . . . . until then, nothing to worry about your 90-days report. However you will probably get called by Immigration when it comes to their planned visit in your home during the "under consideration" period. After this visit, on September 29, you will be able to pick up the stamp of your "1-year Extension of Temporary Stay Permit based on being married to a Thai wife" you will not be on a "visa", your visa is already expired and invalid, you are in Thailand on a "stay permit"

You'll get many wrong answers about this, as it's a little confusing.

Short answer is no, you don't need to do a 90-day report yet.

When you entered Thailand on your 90-day non-O visa, you were not on a stay that allowed more than 90 days, so the responsibility for that had not started yet. When you get the full extension in your passport, the immigration officer will insert a slip of paper (possibly stapled to the inside) that will tell you the date for your first 90-day report.

It's only once you're on a stay that allows greater than 90-days in Thailand that the counting for 90-day reporting begins.
