if a united states or canada legal permanent resident has a secret offshore bank account like in belize or somewhere else in the world and the banking officials there wanted to keep a secret from uncle sam or his canadian counterpart, would this be possible? if the offshore banking officials wanted to hide it from american or canadian officials, could they do it or would the united states and canada investigate it without permission from the banking officials? do banking officials have to cooperate in providing such information? what if banking officials refused to provide such information even though nothing illegal was taking place? can an offshore banker please tell me. thank you.
