yes, it has to be in your account for two months before applying for your one year extension, but, for the initial 90 day visa as soon as it is in your account you can apply. It doesn't matter where the bt400,000 comes from, and as soon as you get your one year extension stamp you can take any, or all of the bt400,000 out of your account, just don't make the mistake of closing your account. It just has to be in your account two months before your next yearly extension.
