Proof of income to who.
I realize it's part of application to Canadian embassy for income letter however they cannot verify it.
Cut/paste from AI...
"The Canadian Embassy in Bangkok will no longer provide income affidavits, also known as income letters, starting April 1, 2025. The embassy cannot verify income and is not legally required to do so.
Explanation
The embassy's practice of issuing income affidavits was informal and not regulated"
