Subject: Self-Employment Letter for Destination Thailand Visa (Workcation Category)

Dear Sir/Madam,

I, [NAME], am the sole founder, owner, and operator of [BUSINESS NAME], a well-established enterprise registered in the United States ([BUSINESS ID]). I established the company single-handedly in [FOUNDING YEAR], and over the past two decades, it has evolved into a robust operation based in [LOCATION], delivering top-tier services to a diverse, international clientele, with all revenue sourced exclusively from non-Thai markets.

I am applying for the Destination Thailand Visa to manage my business remotely from Thailand, drawing on my extensive expertise in entrepreneurship and remote leadership.

As the visionary who built [BUSINESS NAME] from scratch, I oversee all critical aspects remotely, including financial management (such as bill payments and credit transactions), staff compensation through secure digital platforms, innovative marketing to expand my global client base, and comprehensive operational coordination.

These duties are performed entirely online using advanced tools like email, cloud-based systems, and virtual communication, ensuring I maintain full control without any need for a physical presence in Thailand or engagement in local work.

On-site daily operations in [LOCATION], such as client scheduling and equipment upkeep, are expertly handled by my brother, [BROTHER'S NAME], who serves as the on-site manager, guaranteeing smooth functionality while I focus on strategic oversight from afar.

My income is derived solely from [BUSINESS NAME], with regular weekly transfers of [WEEKLY AMOUNT] from the business account to my personal account at [BANK NAME], yielding an annual income of approximately [ANNUAL AMOUNT].

Additionally, I maintain a substantial personal savings balance of [SAVINGS AMOUNT] at [BANK NAME], as evidenced by the enclosed bank statements, tax returns, and supporting financial documents.

These resources affirm my financial independence and ability to sustain myself during my stay in Thailand.

I solemnly affirm that my professional activities fully comply with Thai immigration regulations, as all income originates outside Thailand from non-Thai sources, and I will not participate in any local employment, business ventures, or services within Thailand.

I am fully committed to adhering to all visa conditions and am prepared to submit additional documentation, such as my business registration or further financial proof, if required.

Thank you for considering my application. I am enthusiastic about the prospect of enriching Thailand's dynamic workcation community while continuing to expand my business remotely. Please feel free to contact me at [EMAIL] or [PHONE] for any additional information.

Sincerely,

[Your Handwritten Signature if Printed]

[NAME]

Owner, [BUSINESS NAME]
