It has been reported that the U.S. requested cooperation from the Korean National Police Agency (KNPA) regarding a visit to the United States by HYBE Chairman Bang Si-hyuk and other senior executives, despite Bang being subject to an overseas travel ban tied to a police investigation. Critics say the move may constitute a breach of diplomatic norms, as the U.S. allegedly bypassed formal diplomatic channels and directly singled out individuals under travel bans in a request to a foreign investigative agency.

According to an April 19 report by the Hankook Ilbo, the U.S. Embassy in Seoul recently delivered a letter to the acting commissioner general of the KNPA requesting cooperation to allow HYBE senior executives — chairman Bang Si-hyuk, CEO Lee Jae-sang and vice president Kim Hyun-jung — to travel to the United States.

The stated reasons for the their U.S. visit reportedly included attending celebrations marking the 250th anniversary of Independence Day on July 4, as well as supporting BTS during the group’s U.S. leg of its world tour. Earlier, Donald Trump announced plans for an unprecedented large-scale Independence Day event in Washington, D.C., including a Ultimate Fighting Championship event.

The complication is that Bang and Lee are both subject to overseas travel bans as suspects in a Capital Markets Act violation case. A request to facilitate Bang’s U.S. trip would, in effect, amount to asking police to seek the lifting of those restrictions. Normally, lifting a travel ban requires the Ministry of Justice to convene a review committee and make a determination following a request from the investigative agency.

Clash with diplomatic procedures

Bang is accused of providing investors with false information ahead of HYBE’s 2019 listing, allegedly claiming there were no plans for an initial public offering and obtaining roughly 190 billion won (about $168 million at the time) in illicit gains. Police have already questioned him five times and are now conducting a final legal review. Authorities are expected to decide soon whether to seek an arrest warrant or refer the case for prosecution without detention.

The U.S. request has drawn criticism as a breach of diplomatic norms, departing from standard procedures for transmitting diplomatic communications or handling interagency coordination. It is considered highly unusual for a diplomatic mission to directly ask an investigative agency for cooperation regarding the overseas travel of a domestic criminal suspect.

Reports say the approach itself was also atypical, with U.S. officials first making the request by phone and then delivering a letter by hand. Normally, diplomatic matters or cooperation requests are coordinated through official channels such as the Ministry of Foreign Affairs.
