USA, travelling with more than USD 10,000

Travelling in the United States with such a huge amount of cash is extremely dangerous because civil forfeiture. Your money can be taken at the airport, by the security at the airport a routine traffic stop and practically anywhere else. Once the cops seize the cash they will not charge you (often they won't have anything to charge you with) but the money itself and you will have a lot of difficulties getting it back.

If you send the money by a bank wire to your son, then the banks will file the proper notification paperwork at both ends.

If you carry it into the country in cash, then you need to declare that fact and fill out FinCEN Form 105 for your trip, as you have noted. But you are not "importing" it rather you are "carrying" it in. - https://help.cbp.gov/app/answers/detail/a_id/195/kw/more%20than%20$10000%20cash/

The "receiving person" details mentioned in your post would apply if you sent the money by courier or other means where the responsible party is not physically moving the money. It also applies to bank wires, but the banks usually handle the declaration paperwork for their customers automatically.

There maybe restrictions or declarations in your country of origin to consider as well.

If your son deposits it into his US bank account, then the bank will have to declare that deposit as it is over $10K. But that again is paperwork the bank will handle automatically, with perhaps a few questions for your son.

I would be very careful in the United States with cash, due to Asset Forfeiture.

It's hard to say how high the risk or frequency, but there seem to be many incidents of this occurring. Of the cases I have followed where there is no justifiable cause, most have been unable to get any of their money back even after long legal processes. In some cases the asset owner has been able to negotiate return of a small percentage.

The frequency seems to be higher with local law enforcement, but also exists with state and federal. These cases are kept quiet and charges are rarely levied.

If this is useful, I've entered the USA twice with way more than $10,000 in traveler checks (but not in cash). The procedure is the following: you mark it on the Custom declaration, go to Customs, they check your declaration and send you to the secondary desk. There you are given a simple form, fill it up and give it to them. After that you're done. They didn't ask to see the traveler checks or count them, and generally looked completely uninterested and unexcited about the whole process.

No unusual questions were asked by the Customs, but my bank (where I deposited it), asked whether I declared it to the Customs. I said "yes" and they didn't have any further questions.

WHO MUST FILE: (1) Each person who physically transports, mails, or ships, or causes to be physically transported, mailed, or shipped currency or other monetary instruments in an aggregate amount exceeding $10,000 at one time from the United States to any place outside the United States or into the United States from any place outside the United States, and

(2) Each person who receives in the United States currency or other monetary instruments In an aggregate amount exceeding $10,000 at one time which have been transported, mailed, or shipped to the person from any place outside the United States.

It looks like you both must file since the last word in the first paragraph is "and". While it is perfectly legal and can attract a lot of undesirable attention from the authorities such as the IRS or the department of homeland security. We did this once as a young white couple with three small children in tow and still got subjected to intense questioning.

First: I would NOT use cash because of risk of loss and high currency exchange fee. If you need a cash-like instrument, use travelers checks. These can be replaced if stolen and typically just have a 1% flat fee. They still are subject to declaration.

Electronic transfers are safer, cheaper, and easier on the paperwork. I use http://www.xe.com/xetrade/ to send money to kids abroad. Many banks these days have direct partnerships with other banks in different countries for mutual use of ATMs and low overhead transfer. For example Bank of America works with Deutsche Bank in Germany, Santander in Mexico, China Construction Bank, Westpac in Australia/NZ etc. I recommend talking to your local bank or finding a Bank in your country with ties to the US.

I am writing this because of "J Bergen"s poor answer. Bergen gives some bad advice.

1. You can bring as much currency into the country as you want, as long as you declare it. Otherwise, there will be penalties
2. NEVER STRUCTURE YOUR MONEY: i.e. bring in amounts under $10,000 multiple times. That's as bad as not declaring, and could see your visa revoked.
3. Western Union is not good
4. If you are unsure if the total amount of money (in any currency) you have anywhere (in your bags, pockets, shoe, etc) is equivalent to US$10,000 or more, DECLARE

The USA is a country with an effective, reliable banking system that does a good job serving consumers with virtually no graft or theft. As such, the only people who handle large quantities of cash are:

• fools
• criminals

This may differ dramatically from your country. The US government is primarily concerned with the second, and cares less about the property rights of the first. "A fool and his money..."

So it may be standard practice in your country to deal in cash, but in America it will get a frosty reception because of these prejudices. With an underlying assumption that more likely than not, it is in America's best interests to separate you from your money. There will be a mechanism by which you can appeal for its return, but this could cost a big chunk of $12,500 in lawyer costs.

The way America expects you to do this is via the trusted, western banking system. For instance have your friend generate an invoice on PayPal for the goods or services, and pay them via PayPal. If for some reason you can't do conventional electronic transfers, you need to fix why that is.

Bringing in cash because electronic transfers don't work is just the kind of thing they're on guard for. Customs will know the reasons your wire transfers were disallowed, and will be wary of cash moving on the same route. Effectively you're circumventing the normal way of doing this.

That isn't structuring, but they have a lot in common.

The upshot is that bringing large blocks of cash is a fool's game, and you should expect problems.
