Is In-Country Application of Non-Immigrant R (Religion) from visa exempt possible?

[Nordlys]

Can anyone tell me if in-country application of Non-Immigrant R (Religion) in Thailand is possible for a Japanese passport holder who lands in Thailand visa exempt?  

I was told in another online forum that a Japanese passport holder can apply Thai visa in-country even if they land in Thailand visa exempt, but just about every foreign monastics (monks) who took Bhikkhu ordination to become a monk in Thailand arrives on tourist visa and change to Non-Imm R inside Thailand,  Japanese or otherwise.

In the past, it used to be:
As the process involves a document called TM86  called "change type of visa, การเปลี่ยนประเภท" ,
and as the person in question does not hold a visa proper, it used to be not possible.
However, you might contact your local immigration office and ask for advice.
What is impossible in one province may be possible in another province.
It is also possible, to apply for a Non-I type R visa from abroad, in your case from Japan.
In any case, including applying from abroad, the person in question  needs a supporting monastery in thailand to issue him all the usual documents involved with applying for a Non-I type R visa.
This includes,  a letter of recommendation from the department of religious affairs, an invitation letter from a monastery in thailand, a letter of support from that monastery and others.
