Irish citizenship campaigner Emma DeSouza has been invited to march in this year's St Patrick's Day parade in New York.

The Derry woman recently returned from a trip to the US where she was highlighting what she described as the British government's failure to give domestic legal effect to the birthright provisions of the Good Friday Agreement.

Emma DeSouza is challenging a requirement that she renounce her British citizenship before she can legally identify as Irish.

Last October, an immigration tribunal ruled that the people of Northern Ireland remain British citizens even if they identify as Irish.

Ms DeSouza is challenging being automatically determined to be a British citizen under UK law rather than having a choice of Irish citizenship.

Earlier this month, Emma DeSouza took her campaign to the US and discussed her case with former US Secretary of State Hillary Clinton.

She also met with members of the US Congress on Capitol Hill, including Congressman Richard Neal, chair of the powerful Ways and Means Committee, Congressman Brendan Boyle, and Republican Congressman Peter King.

While in Washington, Ms DeSouza also met the Irish Ambassador to the US Dan Mulhall and members of the Ad Hoc Committee to Protect the Good Friday Agreement.

Today, Emma DeSouza tweeted that following her successful US visit in support of the Good Friday Agreement, she was delighted to share the news that she'd been invited to march in this year's St Patrick's Day parade in New York.
