How long does it take to get a Thai visa from Hanoi and what are the bank requirements for the Non-O visa?

The user successfully received their visa (dtv) from Hanoi within a week. The discussion includes important details regarding financial requirements for the Non-O visa, noting that 800,000 baht must be held in a bank account for 2 months prior to the application and for 3 months after for subsequent extensions. Clarification on the implications of applying for another visa while holding an active re-entry permit is also discussed, indicating that as long as one returns after the permit expires, it shouldn't pose a problem.
