A New Zealand-born man who served with the US Marine Corps for seven years and has spent three decades living in America is now facing deportation after losing a prolonged battle for citizenship.  Paul Canton was born in the Northland town of Warkworth in 1971, before his family moved to Perth, Australia, when he was aged 5.  He first arrived in the United States at age 17 but overstayed his student exchange visa and instead enlisted in the US Marines on March 29, 1991.  During his time with the US Marines, Canton spent a year in Okinawa, Japan, and came close to being deployed to Somalia in 1993.  Paul Canton enlisted in the US Marines on March 29, 1991.

He married, raised a family, and even voted before learning he had never actually become a citizen while applying for a new driver’s licence in 2019.  Canton had initially registered to vote by showing his official military service record and had voted eight times since 2004.  He hired a lawyer, and his case started moving through the courts.  After years of navigating the immigration system, Canton’s hope of continuing to reside in the place he called home was shattered last month.  A federal judge ruled that, despite Canton signing up for military service during the conflict, he did not qualify for citizenship because the conflict had ended by the time he entered active duty, according to a report by Military.com.  Deportation would see Canton return to his birthplace in New Zealand.  Paul Canton has spent three decades in the United States.
