An Irish citizen needs a visa for any trip to the US that lasts longer than 90 days (tourist, business, or transit). Irish people who want to visit the US for less than 90 days can’t get a valid visa in Ireland. It is the traveler’s job to make sure their passport is good for at least three months after they leave the United States.
The goal of the ESTA US Visa program is to make the border safer. Shortly after September 11, 2001, the ESTA US Visa program was given the green light, and it started up for real in January 2009. In response to the rise in terrorist attacks around the world, the U.S. government made the US VISA FOR IRISH CITIZENS program so that security checks could be done on foreign visitors coming into the country.
