Got my stv extension in 1 hour at jomtien. I would have been 40 mins if the lady I rent condo from would have put the correct room number when she submitted TM30 online. The nice lady at immigration spoke to her on my phone and fixed it. No mention of return flight needed like it states on the criteria they gave me. My advice would be don’t stress over anything they are their to help. I’m stamped up to 21st sept so perfect for final deadline stamp as planned 😁
Make copies of everything and sign each copy.
