Can I renew my Non-Immigrant O Visa early and is the 800,000 THB deposit requirement flexible?

You cannot apply for a Non-Immigrant O Visa renewal two months before it expires; the earliest is typically 45 days before the expiration date. Additionally, to meet the financial requirements for renewal, the 800,000 THB must be accessible at all times. While you can keep this amount in a Thai bank account, it should not be in a term deposit if you need to demonstrate access.
