Of all the borders dividing the USA with Mexico, Nogales AZ/Tucson has seen the largest number of undocumented migrants during the last decade and the greatest number of recovered remains of migrants, perished in extreme condition in the desert of southern Arizona. Since 2013, I am photographing on both sides of the border, following deported migrants, as well migrants who try to cross the border to the US to either find work, or meet parts of their families who already live in the US.
