How much money can you bring into the US per family?

When entering the U.S., travelers can bring in up to $10,000 in cash or monetary instruments without having to report it to customs. If a family carries more than this amount, they must declare it on the Customs Declaration form. Failure to declare amounts over $10,000 can lead to the confiscation of the funds and potential legal penalties. Additionally, there is no limit on the amount of money that can be brought into the U.S., but proper declaration is essential.
