Lauri became a full nuncio upon the establishment of complete diplomatic relations between the Vatican and Peru on 20 July 1917. He was later named Apostolic Nuncio to Poland on 25 May 1921, succeeding Achille Ratti. In this post, Lauri negotiated the concordat between the Vatican and the Second Polish Republic.

Eucharistic Congress 1932
Cardinal Lauri served as papal legate to the Eucharistic Congress of Dublin (1932). [3] As his ship arrived in Dún Laoghaire on Monday 20 June, it was escorted into the harbour by aeroplanes flying in formation in the shape of a cross. He travelled in procession the nine miles from Dun Laoghaire to St Mary's Pro-Cathedral in Dublin in the Lord Mayor's Coach, led by the Blue Hussars, a recently created ceremonial cavalry unit.[4] Made a Freeman of Dublin at a ceremony at Mansion House, during his week-long stay, the Legate visited a number of towns including Armagh, Drogheda, and Dundalk.[5]
The closing ceremonies included a High Mass in Phoenix Park attended by an estimated one million people (or one-quarter of the country), who heard Irish tenor John McCormack sing César Franck's Panis angelicus, one of the more noted events of McCormack's career. At the conclusion of the Mass, there was a brief radio address by Pope Pius XI, broadcast throughout the country. This was followed by the Blessed Sacrament carried in procession from Phoenix Park, along the quays to O’Connell Bridge for a final Benediction conducted by Lauri before about a half million people gathered along the quays and streets.[4][5]
I shall never forget the unforgettably glorious days of this Eucharistic Congress . . . all have participated, all have co-operated to make this congress a triumph, government and civic leaders, as well as ecclesiastical authorities, priests, members of religious communities, men, women and children, have all united to make this Eucharistic Congress a plebiscite of love for the Blessed Eucharist, a plebiscite of devotion to the vicar of Christ."[5]
