Answer
True. John Neumann, a Redemptorist priest, was born in Bohemia (part of the modern-day Czech Republic) in 1811 and became a naturalized U.S. citizen in 1848. After serving as the Bishop of Philadelphia from 1852 until his death in 1860, he was canonized by Pope Paul VI in 1977, making him the first and only male U.S. citizen to be formally recognized as a saint by the Catholic Church.
