From the U.S. State Department, checked October 2026. Rules change, sometimes quickly: confirm them on travel.state.gov (opens a new tab), which also shows the current safety advisory, before you book. Only use official government sites to apply for visas and travel authorizations; look-alike sites charge extra.
