Hello everyone, I will be going to Thailand under the visa exemption scheme with the intent to apply for a non-immigrant O retirement visa. I read from the Thailand Immigration website that one of the options for the income verification is to have a “letter of guarantee” from the local embassy. Unfortunately, the local embassy does not issue this letter anymore. I would like to find out if someone have used a “letter of guarantee” from your bank together with a bank statement as proof of enough income to apply for the non-immigrant O visa?
