South Korean passport holders can enter Guam under the Guam-CNMI Visa Waiver Program for up to 45 days without an ESTA or US visa. No fee, no advance application beyond the CBP I-736 form (filled out on the plane or at the airport). Passport must be a biometric e-passport (with the chip symbol) valid for at least 6 months. You need a return ticket on a participating carrier, a completed I-736, and a completed I-94 arrival form.
The Guam-CNMI waiver is separate from the US Visa Waiver Program (ESTA). You can also enter Guam with an approved ESTA ($21, valid 2 years), which allows 90 days and onward travel to the US mainland. If you plan only Guam, the Guam-CNMI waiver is simpler. CBP officers at A.B. Won Pat Airport (GUM) process arrivals quickly since Guam receives massive Korean tourist volume. Korean is widely spoken at hotels and shops in Tumon Bay.
