So I came to thailand with the thailand plus, now that I am here, I am wondering if I can extend my visa at the local immigration office. There were a lot of requirements to get here, PCR Test, Insurance, etc. First off, I still need the immigration form, a photo within 6 months, the fee, but do I need to show proof of insurance for my extended stay, since my original insurance only covered my first 30 days here? Is there anything else that I need?
