My wife and I are on a 60 day TR visa with 21 days remaining. We will go to Krabi immigration in 6 days ( 15 days remaining on TR) to apply for 30 day extension. I found this TM30 online. Is this the correct form I need? Does my hotel have to fill this out? Do we need 1 form each or can we both go on this one. If they approve the extension does it start when my 60 day expires or the day I apply? We already have photocopies of passport and TM6 departure card as well as extra passport photos. Do I have all my ducks in a row? Thank you for any info. Cheers.
TLDR : Answer Summary
The TM30 form is typically filled out by your hotel or landlord and not required directly from you for the extension application. You do need proof of the TM30 submission from your hotel. For the 30-day extension, it will be added to your current visa stamp. When you apply for the extension, it starts from the date your original visa expires.
