How much currency / money / monetary instruments can I bring into the U.S.?
There is no limit on the amount of money that can be taken out of or brought into the United States. However, if a person or persons traveling together and filing a joint declaration (CBP Form 6059-B) have $10,000 or more in currency or negotiable monetary instruments, they must fill out a "Report of International Transportation of Currency and Monetary Instruments" FinCEN 105 (former CF 4790).
If assistance is required, a Customs and Border Protection (CBP) Officer can help with filling out the form.
Please be aware, if persons/family members traveling together have $10,000 or more, they cannot divide the currency between each other to avoid declaring the currency.
For example, if one person is carrying $5,000 and the other has $6,000, they have a total of $11, 000 in their possession and must report it on a FinCEN 105. If a person or family fails to declare their monetary instruments in amounts of over $10,000, their monetary instrument(s) may be subject to forfeiture and could result to civil and criminal penalties.
