Taoiseach Brian Cowen will travel to the United States next month on a trip which is expected to focus on the global economic situation.
Mr Cowen will hold a series of meetings and engagements with key political and business leaders as well as representatives of the Irish community.
It will be his first official trip to the US since he took over as Taoiseach in May.
Mr Cowen met US President George W Bush in Belfast earlier this month.
The pair held brief, informal talks after Mr Bush flew into the north to meet First Minister Peter Robinson and Deputy First Minister Martin McGuinness on the final leg of a European trip.
During his two-day trip to the US, the Taoiseach will visit New York for a series of engagements to the Stock Exchange on July 16 and a keynote address at the Wall Street 50 Dinner the following day.
A Government spokesperson said the Taoiseach’s meetings are expected to focus on economic issues including the global situation with high energy prices and the credit crunch having an effect around the world.
Mr Cowen is also likely to explore the possibility of developing Irish-US relations, immigration reform and the undocumented Irish in the US.
Around 50,000 Irish-born people are believed to be living and working illegally in the US.
