He did it all himself, its not too onerous almost exactly the same information that I had to supply for renewing my own O "retirement" visa. I would suggest you go into your nearest ID office and ask one of their volunteer interpreters to walk you through it all?
No problem, glad you found it! I always check mine after they give it back because in December 2020 I went through the "Drive In" at Phuket and they forgot to change the year to 2021 and said I had to report back sometime in March 2020!!!
