Move your money in one lump sum, at one time, to one place. It will generate one report which will get lost in the shuffle.
Banks are on the lookout these days for people breaking up deposits, withdrawals or transfers in multiple small amounts, over several time periods. It's called "structuring", and they have decided that they don't like it.
The government has turned your own bank into a government snoop, and the Homeland Security nazis will attempt to grab anyone's money who is doing this, under the pretense of "the war on terror" or the "war on drugs", and you will spend a lot of time and money trying to get your own money back if you, and they, do this.
And for those "know-it-alls" responding, ask your banker in the US about SARs. According to my own friendly banker, who is just as opposed to all of these new crapola regulations, is that now, under the ever-expanding PATRIOT Act the limits for reporting transactions are now $2500, not $10,000. Any Postal money orders or wire transfers for amounts over $700 are also supposed to generate additional paperwork that will be handed over to the US government.
