In 1991 Lesly Yajayra Perdomo (“Perdomo”), a citizen and native of Guatemala, joined her mother in the United States. In April 2003 the Immigration and Naturalization Service charged her as removable because she unlawfully entered the United States in 1991. Perdomo conceded removability but requested asylum, withholding of removal, and relief under the United Nations Convention Against Torture. Perdomo sought asylum because of her fear of future persecution as a member of a particular social group of “women in Guatemala between the ages of fourteen and forty.” Perdomo explained she was fearful because of: (1) the large number of women killed in Guatemala; (2) the failure of the Guatemalan government to respond appropriately; and (3) the lack of explanation for the killings. The immigration judge denied Perdomo’s requests. The Board of Immigration Appeals (the “BIA”) affirmed the denials and rejected the particular social group definition, “women in Guatemala between the ages of fourteen and forty” and Perdomo’s revised group definition, “all women in Guatemala,” as too broad to qualify for protection. The Ninth Circuit granted Perdomo’s petition for review and held that prior case law established that, “women in a particular country, regardless of ethnicity or clan membership, could form a particular social group.” The court noted that the size and breadth of the group, “all women in Guatemala,” did not preclude it from qualifying as a protected social group and that the BIA erred when it held to the contrary. The court remanded the case to the BIA to determine whether “all women in Guatemala” is a particular social group and, if so, whether Perdomo qualified for asylum.
