Have just been to Phetchaburi immigration to renew my non o visa based on retirement,this is the 10 th time I have renewed only today to be told I need 1 years bank statement in stead of the normal 6 months statement I have had for the last 9 times,I don't know if this is a new immigration rule for Phetchaburi,I have been in touch with the Bangkok bank and now have to wait on a statement from Bangkok bank head office,so I'm just putting this on here as a heads up
