The first thing you usually hear at a bank counter after deciding to send your child abroad to study is, "You'll need to designate a transaction foreign exchange bank." For a parent hearing that for the first time, it sounds like an unfamiliar procedure, but this one designation saves a lot of repeated paperwork every time you send tuition and living expenses afterward. Skip it, and split remittances across several banks instead, and you can end up hitting remittance limits or getting asked for the same supporting documents over and over.

Study-abroad funds start with "designation," not a "limit"

Ordinary overseas remittances come with an annual cap, but study-abroad expenses work differently. Foreign exchange transaction regulations let a student studying abroad designate a transaction foreign exchange bank and, after submitting documents proving the study-abroad status, send tuition and living expenses through that bank with no amount limit. Sending money through undesignated banks on an ad hoc basis can mean being asked for study-abroad documents fresh each time, or running into remittance caps -- so once study abroad is confirmed, the first thing to do is apply at your main bank to designate it as your transaction foreign exchange bank for study-abroad remittances.

The documents you submit the first time you designate a bank

When you apply to designate a transaction foreign exchange bank, you submit documents confirming the study-abroad status -- an admission letter or a certificate of enrollment. Many banks also require the student's own ID, and if the student is a minor, documents confirming the family relationship. Requirements vary somewhat by bank, so checking the required document list at the counter or call center before applying lets you handle it all in one visit.

The threshold banks still watch -- $100,000 a year

Being designated as a transaction foreign exchange bank doesn't mean the amount is unlimited with no oversight at all. If the annual remittance amount exceeds US$100,000, the transaction foreign exchange bank is required to notify the National Tax Service and the Financial Supervisory Service of that fact monthly, by the 10th of the following month. That isn't a separate reporting obligation for the student -- it's a notification procedure the bank carries out with the relevant authorities -- but it's worth keeping in mind that a run of large remittances can put you on the radar for a National Tax Service source-of-funds check. If tuition is expensive or siblings are studying abroad together and your annual remittance total is approaching this threshold, it's safer to prepare documentation in advance that explains the purpose of the funds and their source, such as a withholding tax receipt for earned income or business-income records.

The document you resubmit every year -- don't forget the enrollment certificate

Designating a transaction foreign exchange bank isn't a one-time procedure. Each year, you must resubmit to the bank a certificate of enrollment or similar document issued by the head of the overseas educational institution confirming enrollment status, in order to keep receiving study-abroad remittances. If you miss the window to get that certificate issued and submitted to the bank around the start of a term, you can end up with a delayed remittance right when a tuition deadline is looming. As covered in tuition is just the start of international school fees, what counts as "tuition" is often broken out into dormitory fees, textbook fees, and more, so it's worth planning remittance timing item by item.

A separate matter from the tax deduction

The remittance procedure and tax benefits are separate systems. Sending study-abroad funds without a hitch doesn't automatically make that tuition eligible for the education expense tax deduction. In particular, since whether a foreign school's tuition qualifies for the deduction depends on the school's accreditation status, not the student's nationality, separately from your remittance paperwork you'll need to confirm the school is a recognized educational institution before you can use a tuition-payment certificate on your year-end tax settlement.

Don't forget health insurance while studying abroad

While you're focused on remittance issues, domestic health insurance is easy to overlook. If you go abroad long-term for study without filing a suspension of benefits with domestic health insurance, premiums keep coming out for coverage you're not using. Adding the health insurance suspension and reinstatement filing dates to the same calendar as your remittance planning cuts down on that double cost.

When study abroad ends and the student returns

Once study abroad ends, or the student returns partway through, there's no more reason to keep the transaction foreign exchange bank designation active. Not notifying the bank and canceling the designation doesn't cause immediate harm, but if transactions keep running under the study-abroad label, it can complicate verification later when they mix with remittances for other purposes. Once a return date is confirmed, notifying the bank and closing it out keeps your next transactions clean.

Carrying cash out of the country -- the $10,000 threshold

Some families carry exchanged cash out of the country in person instead of wiring it. In that case, if the foreign currency you're carrying is US$10,000 or less, you don't need to file a separate declaration with customs. If you're carrying more than $10,000 out of the country, you must file a foreign exchange declaration with the Korea Customs Service, so if you're planning to prepare initial settling-in funds as cash, check this threshold first.

Summary -- what to confirm in order before sending your child abroad

Once study abroad is confirmed, first designate a transaction foreign exchange bank and submit study-abroad documents such as the admission letter. After that, resubmit a certificate of enrollment every year to keep the designation active, and if your annual remittance total is approaching US$100,000, prepare source-of-funds documentation in advance. Check the school's accreditation status separately from the remittance procedure to determine tax-deduction eligibility, and don't forget to file the health insurance benefit suspension. Specific document lists and procedures can vary by bank and by point in time, so it's safest to reconfirm with your bank's foreign exchange counter before sending money.
