Can I obtain a Non-O (marriage-based) visa in Vientiane without a full 3-month bank statement?

The user is inquiring about the possibility of obtaining a Non-O (marriage-based) visa in Vientiane without having the required full 3-month bank statement showing 400,000 baht, as they only have 2.5 months of account history. Previous experience in Savannakhet suggests that financial proof may not always be requested. Commenters advise that while three months of statements are typically necessary, the actual availability of funds for that entire period might not be strictly enforced.
