I will get a Non Immigrant O Visa for my next visit, the question I have ... To open a bank account what is the customary amount required to just open the account for starters. I am not necessarily trying to deposit 800,000 for one year extension. Primary goal is to open a Thai account and slowly bring to 800,000. I will be leaving in 60 days with the Non-O Visa. Again, looking to just get and maintain an active Thai Account for future retirement Visa long term.
