Can I apply for a Thai 'O' visa based on marriage if my income is held in a joint bank account?

@Robert *****************

When asking this question correctly worded, Chat GPT gives me the following reply (however related to the Royal Thai Embassy Washington DC):

For a Thailand Non-Immigrant O (Family) visa, financial proof can be in the form of a joint bank account, but proof of relationship (like a marriage certificate or birth certificate) must also be provided, according to the Thai Embassy in Washington D.C.

If submitting a joint account statement, be prepared to show evidence of the relationship between the applicant and the account holder(s).

Details, General Requirement:

A Non-Immigrant O visa for family purposes generally requires proof of sufficient funds to cover the stay in Thailand.

Joint Accounts:

While joint accounts are often accepted, the Thai Embassy may require additional documentation to confirm the relationship between the applicant and the account holder(s).

Proof of Relationship:

This can be a marriage certificate, birth certificate, or other documents that establish the family connection between the applicant and the Thai national.

Minimum Balance:

The minimum balance required may vary, but generally, it's around 400,000 THB (approximately $11,000 USD) or a monthly income of 65,000 THB (approximately $1,800 USD), according to the Ministry of Foreign Affairs.
