A-B- (plaintiff) was a native of El Salvador. A-B- stated that her ex-husband, with whom she shared three children, repeatedly abused her. A-B- claimed that she was eligible for asylum because she was persecuted on account of her membership in the purported social group of “El Salvadorian women who were unable to leave their domestic relationships where they had children in common with their partners.” The immigration judge denied relief and ordered A-B- removed to El Salvador. The judge denied the asylum claim because, among other reasons, the group in which she claimed membership did not qualify as a social group within the meaning of Immigration and Nationality Act § 101(a)(42)(A). The judge also stated even if the group did qualify, A-B- failed to establish that her membership in a social group was a central reason for her persecution. A-B- appealed the immigration judge’s decision to the Board of Immigration Appeals (the board). The board reversed with an order to grant A-B- asylum. The bard concluded that A-B-’s social group was substantially similar to a group the board had recognized in its prior decision of Matter of A-R-C-G-, 26 I&N Dec. 388 (2014). The Attorney General then issued a decision in response.
