What are the requirements for renewing an annual visa in Petchaburi, particularly for proving income?

Individuals looking to renew their annual visa in Petchaburi should be aware that proof of income is a critical requirement. Specifically, if you're using monthly income from abroad to meet financial criteria, you must provide 12 months of incoming overseas transfers deposited into a Thai bank account in your name. However, due to recent changes in consulate issuance of notary letters, immigration officers may show leniency if you cannot provide the full 12 months' worth of transfers. It's also essential to clarify which type of visa extension you are applying for, such as retirement or family reasons.
