米領サモア：出発前に知っておきたいこと

重要ポイント

  • American Samoa has separate entry rules from the mainland US: a US visa or ESTA alone does not replace its visitor permit.
  • Apply at least 72 hours ahead, excluding weekends and holidays; some travellers need a local sponsor to apply in person.
  • Carry USD cash for small businesses and outer islands; most ATMs are on Tutuila.

入国とビザ

Entry is governed separately from the US mainland. US-visa/Green-Card holders and citizens of US visa-waiver countries can request a non-extendable 30-day permit online. Other foreign visitors need an eligible local sponsor to apply in person. Check Legal Affairs for your nationality and any US-citizen/national documentation requirements.
