Can I apply for an extension soon (a week or so) after arriving in Thailand? Australian passport so have a 45 day visa exemption and going to apply for an extension. I have a copy of our TM30 from our host who we are with for 1 month (within the 1st 45 days) after that we want to move around a bit so hoping to get the extension while we are at here. In Chiang Rai. Thanks
TLDR : Answer Summary
An Australian passport holder can apply for a visa extension in Thailand shortly after arriving, typically within 30 days prior to the expiration of their initial visa stamp. In Chiang Rai, a TM30 form is usually required for extension applications, similar to Chiang Mai. Travelers can also consider options like obtaining a 60-day visa from Laos and then extending it in Thailand for a total of 90 days.
