Went to the Bluport immigration office in Hua Hin to start my non O visa for retirement. 2 hours in the queue, presented all my paperwork, was told I need to have at least 15 days left on my visa to apply. They gave me a 30 day extension, 1900 baht.

They told me to go to the main immigration office here and apply the sooner the better, but at least with 15 days or more on my visa.

I had 7 days left on mmy visa and the 800000 baht had just reached the 2 month requirement. I don't recall seeing the 15 day requirement before.
