@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"
