Try to use a copy of an hotel TM30 report in most immigration offices in Thailand for lets say a 1 year extension or even a 90 days report in any Chonburi immigration office, I think there are three of them. As a tourist going for a 30 days extension the hotel TM30 copy will work. If you're staying in Thailand long term,why would you even use the copy from an hotel? My TM30-receipt has been stapled inside my passports for years. Now I take copies of copies of it, to keep it in one piece.
