Once the 800k is in the account 2 months before A-O visa is there a minimum amount of days it needs to be untouched? How much must always remain in the account, 400k? And when should it be refilled up to 800k, 2 months before renewal? Also, can the A-O be renewed in Thailand or only in my home country from where I received the A-O visa? One of the mandatory documents is a full year insurance coverage, correct?
