12. Money and Other Monetary Instruments

You may bring into or take out of the country, including by mail, as much money as you wish. But if it's more than $10,000, you'll need to report it to Customs. Ask the Customs officer for the Currency Reporting Form (CF 4790). The penalties for not complying can be quite severe.

"Money" means monetary instruments and includes U.S. or foreign coin currently in circulation, currency, traveler's checks in any form, money orders, and negotiable instruments or investment securities in bearer form.
