It's that time again. Renewing my Non-Imm O Long Stay Visa next week. Mon and Wed are holidays so planning on getting Bank Letter (confirmation) on Tuesday and then going to Immigration on Thursday morning. Question: how long is the Bank Letter valid for? Thanks in advance! (googled it but couldn't find that detail)
TLDR : Answer Summary
The validity of a Bank Letter when renewing a Non-Imm O Long Stay Visa in Thailand typically varies depending on the immigration office. In Bangkok, it is valid for 7 days from the issuance date, but some users have reported that it may effectively expire on the 7th day, making it valid only for 6 days. It's also important to consider that requirements may differ across the 70+ immigration offices in Thailand.
