Potential problem discovered today. Some immigration offices may ask you for proof your bank deposit came from abroad. Many people use online banks like Wise. But Wise send from their Wise London bank to a partner bank in Thailand, and then on to your bank. So your deposit's code in your Thai bank is not from abroad. Immigration can therefore make this an obstacle - that needs overcoming - to get your visa. Note: not all offices or officers ask for this apparently.
UPDATE: According to others, it seems this problem has been solved by Wise giving an option to send "funds for longstay". If, like me however, you sent the funds before this option was available, the problem remains. You will most likely have to resend the funds from abroad. My local office will not accept the Wise (funds sent) statement as proof.
TLDR : Answer Summary
When transferring money to Thailand using Wise, it's essential to select the "Funds for Long Stay in Thailand" option to avoid potential immigration problems. Some immigration offices may require proof that bank deposits originated internationally, which can become an issue if the funds are routed through a partner bank in Thailand. While not all offices enforce this rule, being proactive by using the correct transfer option and ensuring proper documentation is advisable. If prior transfers were made without this option, recipients may need to resend funds directly from abroad. Overall, understanding these nuances can streamline the visa process for expats.
