ESTA (Visa Waiver Program)：アイルランド → アメリカ合衆国
Irish citizens don't need a US visitor visa for short trips — Ireland is in the Visa Waiver Program, so you apply online for ESTA and can visit for tourism or business for stays of 90 days or less.
Visa-free travel to the United States under the Visa Waiver Program — apply online for ESTA instead of obtaining a visitor visa.
- 有効期間
- ESTA approval is typically granted for a two-year period or until your passport expires, whichever is sooner
- 入国回数
- Usable for repeated trips while valid — a new ESTA is required if you get a new passport or your details change
- 1回の最大滞在日数
- Stays of 90 days or less per visit for tourism or business
手続き開始時期
出発日の 3 日〜30 日 前から手続きを開始してください。
Ireland is on the US Visa Waiver Program country list, so Irish citizens can visit the US for tourism or business for up to 90 days without a visa — provided they hold an e-passport and get ESTA approval before travelling.
Apply on the official ESTA portal (esta.cbp.dhs.gov) — the application fee is $40.27 USD. You can apply at any time before travel, but CBP recommends applying as soon as you start planning the trip, before booking tickets.
Make sure your ESTA shows as approved before boarding — travellers without an ESTA approval can be denied boarding, delayed, or refused admission at the port of entry. If ESTA is denied, the only route is a regular visitor (B) visa at a US embassy or consulate.
ESTA authorises you to board, but it does not guarantee entry: a US Customs and Border Protection officer determines admissibility when you arrive, and grants a stay of 90 days or less.

知っておくと便利
- ESTA approval is not a guarantee of entry — a CBP officer determines admissibility when you arrive.
- You must use an e-passport (with an embedded chip); emergency or temporary passports must also be e-passports.
- Travel to or presence in Cuba on or after January 12, 2021, or in DPRK, Iran, Iraq, Libya, Somalia, Sudan, Syria or Yemen on or after March 1, 2011 (or dual nationality with certain of those countries), makes you ineligible for the VWP — you'd need a visitor (B) visa instead.
- If your ESTA is denied, the only way to travel is to apply for a nonimmigrant visa at a US Embassy or Consulate.
- Apply only on the official esta.cbp.dhs.gov portal — third-party sites charge extra and are not endorsed by the US government.
