Chaengwathana or whatever is spelt is your best option.

@Ellie ******

Thanks mate!

I have a question and I know it is kind of silly. Could one apply for this visa if he/she is in Thailand already?

@Benjamin *****

Yes, except for the TM30; they did not ask for it, and number 4; they only needed one.

Unless they extend it again.

Yes. They should not have any problem with that, though. The safest option.

So I could say they do not issue these letters. Even I could speak to them (my embassy) and to get their support just in case Immigration contacts them Although I do not think they will go that far, right? Or am I just being paranoid?

My immigration office is not Chaengwatthana but the one that is in a remote place. Office K. TM 30; yes, she did, but we have not received any reply yet. My embassy says that if I need the letter, they can issue it. But they said that the people who had applied for this extension were not required such letter.

But I have been working on a strategy; it is very straightforward, veyr simple. I am going to go on May 25th with all the documents required 'by tradition', so in the unlikely case they asked me for a letter from my embassy, even though my embassy confirmed they had not been issuing those for a long time, I can make an appointment or similar on time before the deadline. What do you think about such strategy?

Contact them. They will let you know if they know cases of people asking for such letters. Here in Bangkok they are quite relaxed about it. At least, it is what my embassy told me.
