Assuming youβre from South Korea, you do not need a visa to visit Norway for up to 90 days. However, in trying to determine what documents it may be advisable for you to take with you on your trip, a good rule of thumb is to have available the same documents youβd use to apply for a visa to show to Immigration officers if asked. A list for Norway is available here https://www.norway.no/contentassets/a7bc30faaf4144788590ef48e8a7c750/document-checklist-visitors-visa.pdf
Your personal circumstances will guide which documents are relevant. This might typically include, for example:
passport, valid for at least 3 months beyond your planned date of return
proof of legal residence in the US
documents demonstrating intention to leave and means of support during your trip (accommodation, financial - see https://ec.europa.eu/home-affairs/sites/homeaffairs/files/e-library/documents/policies/borders-and-visas/schengen/docs/handbook-annex_25.pdf#29)
travel medical insurance, coverage at least β¬30,000. See the visa documents checklist for other minimum requirements.
a notarised letter of consent from parent(s) authorising travel, if under 18 (Note: I could not find any definitive reference to this as a mandatory requirement for visa-free entrants. I recommend you check with the local Norwegian Embassy/Consulate).
