• Korean climbers’ ESTA approvals for Salt Lake City 2025 World Cup revoked two days before departure.

Several Korean athletes and their coach have been denied entry to the United States 🇺🇸 just days before the highly anticipated Salt Lake City World Cup climbing competition, scheduled for May 23-25, 2025. This sudden development has sent shockwaves through the international climbing community, raising urgent questions about U.S. visa policies and the broader impact on global sporting events. Among those affected is Lee Dohyun, a renowned Korean climber, whose experience highlights the unpredictable nature of U.S. travel authorizations for international athletes.
What Happened: Korean Climbers Blocked from Entering the USA

On May 21, 2025, Lee Dohyun publicly announced that his previously approved Electronic System for Travel Authorization (ESTA) had been unexpectedly cancelled. Dohyun, along with several other Korean male climbers and their coach, had planned to travel to the USA 🇺🇸 to compete in the Salt Lake City World Cup, a major event in the International Federation of Sport Climbing (IFSC) calendar. The team’s ESTA approvals, initially granted on April 28, 2025, were revoked just two days before their scheduled departure.
Despite urgent attempts to secure alternative visas, the Korean team was unable to obtain the necessary documentation in time for the competition. This left the athletes unable to participate, disrupting their professional plans and raising concerns about the reliability of travel authorizations for international sports competitors.
Why Were the Athletes Denied Entry?
The specific reasons for the ESTA cancellations have not been made public by U.S. authorities. However, the incident comes amid a period of stricter immigration and travel policies in the United States 🇺🇸. In March 2025, new rules were introduced that require non-U.S. citizens to:
- Register their local address while in the United States
- Carry proof of registration at all times
– Potentially submit fingerprints, depending on citizenship and legal status
These rules apply differently based on a traveler’s status:
– Visa holders, green card holders, and Canadians must update their address information
– Visa Waiver Program (ESTA) travelers face separate requirements
Additionally, the U.S. government has increased penalties for failing to comply with these administrative rules. On February 5, 2025, the Attorney General issued a directive to pursue federal charges for non-compliance, signaling a tougher approach to immigration enforcement.
The Salt Lake City World Cup: A Key Event in International Climbing
The Salt Lake City World Cup is a cornerstone event in the IFSC World Cup series. In 2025, the United States 🇺🇸 is hosting three major climbing competitions:
- Para Climbing World Cup in Salt Lake City (May 20-25, 2025)
- Boulder World Cup in Salt Lake City (May 20-25, 2025)
- Speed World Cup in Denver (late May/early June 2025)
These events attract top athletes from around the world and are critical for world rankings, Olympic qualification, and the development of the sport. The Boulder World Cup, already underway as of May 20, 2025, is particularly significant for athletes like Lee Dohyun, who have trained for months to compete at the highest level.
How ESTA Works: The Visa Waiver Program Explained
The Korean athletes were traveling under the Visa Waiver Program (VWP), which allows citizens from participating countries, including South Korea 🇰🇷, to visit the United States 🇺🇸 for up to 90 days without a visa. Instead, travelers must obtain an ESTA—an online travel authorization that screens applicants before they board a flight to the U.S.
Key points about ESTA:
– ESTA is not a visa; it is a pre-travel authorization for short visits
– Approval does not guarantee entry; U.S. Customs and Border Protection officers make the final decision at the port of entry
– ESTA approvals can be revoked at any time, even after initial approval

The Human Impact: What This Means for Athletes
For Lee Dohyun and his teammates, missing the Salt Lake City World Cup is more than just a lost opportunity to compete. The consequences are far-reaching:
- World Rankings and Qualification: Missing a World Cup event can affect an athlete’s international ranking and their chances of qualifying for future competitions, including the Olympics.
- Sponsorship and Career Development: Many athletes rely on international exposure to attract sponsors and advance their professional careers. Being unable to compete can lead to lost income and missed opportunities.
- Team Dynamics and National Representation: The absence of a national team at a major event can impact team morale and the country’s standing in the sport.
According to analysis by VisaVerge.com, sudden changes in travel authorization can disrupt not only individual careers but also the integrity of international competitions, as teams may be forced to compete without their full roster.
Why Did ESTA Approvals Get Revoked?
While U.S. authorities have not provided specific reasons for the revocations, several factors could be involved:
- Increased Security Screening: The U.S. has tightened its screening processes for all travelers, especially those attending large international events.
- Administrative Errors or Incomplete Information: Sometimes, discrepancies in application details or missing information can trigger a revocation.
- Policy Changes: New rules introduced in 2025 may have affected how applications are reviewed, especially for groups traveling for professional purposes.
It’s important to note that ESTA is always discretionary. Even after approval, U.S. authorities can revoke it at any time, and travelers have no guaranteed right to enter the country.
What Can International Athletes Do?
For athletes and teams planning to compete in the USA 🇺🇸, this incident underscores the importance of:
- Applying for travel authorizations as early as possible
- Monitoring application status regularly, even after approval
- Having backup plans, such as applying for a B-1/B-2 visitor visa, which may offer more stability than ESTA but requires a longer application process
Athletes who experience ESTA revocation can attempt to apply for a B-1/B-2 visa at a U.S. embassy or consulate. However, this process can take weeks or months, making it difficult to secure a visa on short notice.
The Role of Sports Federations and Organizers
The IFSC and other international sports bodies face growing pressure to:
- Advocate for streamlined visa processes for athletes, especially for major competitions
- Work with host countries to ensure fair access for all qualified competitors
- Develop contingency plans in case athletes are denied entry, such as remote participation or alternative venues
Some federations have begun to liaise directly with immigration authorities to secure group visas or special waivers for athletes. However, these efforts are not always successful, especially when policy changes occur with little warning.
Broader Implications: Immigration Policy and International Sports
This incident is not isolated. In recent years, athletes from various countries have faced visa challenges when competing in the USA 🇺🇸 and other nations with strict entry requirements. The reasons often include:
- Heightened security concerns
- Administrative backlogs
- Changing political climates
For global events like the World Cup, the ability of all qualified athletes to participate is essential for fair competition. When immigration policies prevent participation, it can undermine the legitimacy of the event and discourage future international engagement.
What Should Athletes, Coaches, and Teams Do Next?
If you are an athlete, coach, or team manager planning to attend an event in the USA 🇺🇸, consider these steps:
- Start the visa or ESTA process as early as possible—ideally several months before the event.
- Check for recent policy changes on official government websites, such as the U.S. Department of State.
- Maintain accurate and up-to-date information on all application forms, including travel history and contact details.
- Prepare documentation showing the purpose of your visit, such as invitation letters from event organizers, proof of accommodation, and return flight bookings.
- Monitor your ESTA or visa status regularly, especially in the weeks leading up to your trip.
- Have a backup plan in case of denial, such as applying for a different visa category or contacting your national sports federation for assistance.
The Response from Organizers and Authorities
As of May 23, 2025, neither USA Climbing nor the IFSC has issued an official statement regarding the denied entries. The Salt Lake City World Cup is proceeding as scheduled, but the absence of the Korean team has not gone unnoticed by fans and fellow competitors.
Lee Dohyun and his teammates continue to seek emergency visa solutions, but the likelihood of obtaining approval in time for the event remains slim. This situation has prompted calls for greater transparency and consistency in how travel authorizations are handled for international athletes.
Real-World Example: The Impact on Lee Dohyun
Lee Dohyun’s experience is a stark reminder of the challenges athletes face when competing internationally. Despite following all required procedures and receiving initial approval, Dohyun’s ESTA was revoked at the last minute, leaving him unable to represent his country on the world stage.
For Dohyun, the consequences are personal and professional:
– Lost opportunity to compete at a major event
– Potential drop in world rankings
– Disappointment for fans and sponsors
His story is not unique. Other athletes have faced similar setbacks, often with little explanation or recourse.
Looking Ahead: What This Means for Future Events
The denial of entry to Korean climbers at the 2025 Salt Lake City World Cup is likely to have lasting effects on how international sports events are organized in the USA 🇺🇸. Organizers may need to:
- Work more closely with immigration authorities to anticipate and resolve potential issues
- Provide clearer guidance to international teams about visa and travel requirements
- Consider alternative venues if access cannot be guaranteed for all qualified athletes
For athletes and teams, the incident is a reminder to plan for uncertainty and to seek support from national federations and international governing bodies.
