As an 'owner', Shareholder and Director of my Thai Company I was told by the Visa Agent (my Accountant) that I had to provide a copy (simple scan & print) of my University Degree. I doubted this to be true that it was required. But I had the original - made a scan - then printed a copy. Signed it on the bottom and it was included in my WP, B Visa and one year Extension. It was easy and harmless and maybe beneficial - so I provided it.

Option B is not a functional option - it is just not part of the normal process for the O-A visa

Thus my comment before it was explained

The reason for so many back and forths was not explained in the OP

Flight tickets

Your plan seems rather expensive for no reason

Stay two months on a SETV 60 days Single Entry Tourist Visa.. Then can Extend another 30... 90 total days maximum.

Apply for and purchase a 30 day Extension at the local immigration office 1900 Baht.

You only need 3 but 30 days is the only extension available

Immigration office dependent... Other comments speak to that

Good for the backlash
