Just wanted to update my visa ext application (based on Thai wife) in case it's of use for others. Went to Surin Immigration on 22nd December with all docs, application, bank statement, house photos etc, immi officer told us we must have a "Witness" (signed photocopy of witness ID card), we returned next day with Phu Yai Ban signed copy, 3 days later got call from Immigration giving us 3 hours notice of visit (2 witnesses are required to sign statements to the effect they know the applicant), all went smoothly thereafter, I collected visa last week. I understand why Immigration might want to give such a short notice of visit but best to have a few people on standby for the visit as Immigration were more interested to ask those people questions regarding the applicant than anyone else (5 Immigration officers turned up in a Police minibus to our house). I must go in person to Immigration for the first 90 day report, hopefully i can do the online option thereafter. Jock.
