Hogan Lovells will merge with Mexican law firm Barrera, Siqueiros y Torres Landa on Aug. 1, becoming the latest U.S. law firm to open an office south of the border to boost its Latin American presence.

BSTL, which has 70 lawyers in Mexico City and Monterrey, will be known as Hogan Lovells BSTL following the merger. The offices will give Hogan Lovells 47 office worldwide and four in Latin American. The Washington-based firm has a small office in Venezuela and partnerships in Sao Paulo and Rio de Janiero.
