Thanks for this. While item 3 with the time limitation is interesting, I don't expect anybody to take action when the application process is delayed. It would be kind of counter-productive, methinks.
I re-read item 4 on the website you linked. The applicant needs to be able to conduct a conversation by speaking and understanding the Thai language and present proof of this. So, the Primary School Degree (ป.6) that some of us have will be sufficient. While a certificate from a university will be accepted, there is no mentioning of Chula as was originally posted. It also clearly says that only speaking and understanding is required, no reading or writing. My interpretation of this is that the applicant should be able to conduct a simple conversation (degree of simplicity to be decided by the institution issuing the certificate, and the institution must be accredited by the Ministry of Education), something an applicant will be able to do anyway, Why would anyone apply for a citizenship without speaking the language at least basically, I wonder.
So, all is cool. The Thai government just wants to establish that that the applicants speak basic Thai. The German government also requires that. I don't know about other countries, such as the US or Australia.
