Transferring about $10,000 USD from US to Korea (are there any reporting or other limit requirements)?

Hi. I'm an expat living in South Korea. I want to transfer about 10k USD from my US account to my Korean account. Does this trigger any kind of flag or reporting requirement? If so, should I just transfer 9k or 9k and some change? I'm not trying to hide anything but I just don't want to miss a reporting requirement. I don't know of any for transferring my own money from a US account to abroad (or vice versa) except for if it were in cash at customs.
