What validity do I need on my Irish passport for overseas travel?
This depends on where you're travelling to.
Republic of Korea and other Asian Countries
You must travel on a valid Irish passport when you enter the Republic of Korea (South Korea) and the date of expiry on your passport must extend beyond the period you plan to stay in Korea. However, since Immigration rules surrounding passport validity and clearance at immigration are subject to change we strongly recommend you consult the Korean Immigration Service while in the RoK (South Korea) or the Embassy of RoK (South Korea) in Dublin while in Ireland, before you plan to travel.
Travellers should be aware that the entry requirements of almost all Asian countries (not South Korea) stipulate that passports must be valid for at least six months. If you have less than six months validity on your passport, you will not be allowed to enter many Asian countries and will need to apply for a new passport. This process can take up to 6-8 weeks.
Your Irish Passport must be valid up to your return date.
Your Irish Passport must be valid up to your return date. And you must also get an Electronic System for Travel Authorisation (ESTA) under the Visa Waiver Programme for entry into the United States. You can find more information on the US Embassy in Ireland's website, if you are currently resident in Ireland. You can also find more information on the US Embassy in Korea’s website, if you are currently resident in RoK (South Korea).
All other countries
The passport validity required for countries outside of the European Union and the United States varies greatly so contact your travel agent or the embassy of the country you're travelling to for the most up-to-date requirements.
