What is the process for my 90-day report in Thailand on an O-A visa, and can I take my Cambodian partner with me?

As a holder of an O-A visa in Thailand, you are required to report your address every 90 days. Since you reside in a rented apartment under your partner's name, it is necessary to ensure that your address is correctly represented in your report. You can bring your Cambodian partner with you to the immigration office when fulfilling this reporting requirement, as it may help clarify your living situation. Make sure to check the specific documents needed for the report, such as your rental agreement.
