In 2025, the U.S. visa refusal rate for South Korean nationals applying for B1/B2 visitor visas climbed to 24.73 percent. This shift follows a period between 2021 and 2024 when refusal rates for these applicants typically fluctuated between 14 and 18 percent.
Why it matters
The rising rejection rate reflects a tightened approach to visitor visa screening for South Korean applicants, which is calculated on a fiscal year basis. The total number of visitor visas issued to South Korean citizens fell to 12,226 in 2025, down from 15,508 in 2024.
The 2025 visa refusal rate for South Korean applicants surged to 24.73 percent, up 9.76 percentage points from the prior year. Authorities continue to process these B1/B2 applications under screening protocols that account for short-term business or travel purposes.

Political Context
Rising visa refusal rates face pushback from diplomatic advocates who argue these hurdles strain international partnerships. Critics suggest that more stringent screening protocols may create unnecessary economic friction for business travelers and short-term visitors.
South Korean nationals seeking entry to the United States for business or tourism may face increased uncertainty during the application process. Applicants should prepare for more rigorous documentation reviews and potential delays given the recent surge in refusal rates.
The takeaway
Travelers should anticipate heightened scrutiny when applying for U.S. visitor status as historical approval trends shift. Staying informed about documentation requirements is essential for those planning short-term stays in the United States.
