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.
