Yolanda Miranda, currently at USCIS El Paso Field Office will be the replacement for Warren Janssen as the head of the USCIS office in Cd. Juarez, Chihuahua, Mexico.
Though I do not know Ms. Miranda personally, my impression has been that the El Paso USCIS office is fair and perhaps even generous with waivers, so I do not expect to see any changes in adjudications. This remains to be seen when Ms. Miranda assumes her position. She is expected to start sometime in August of this year. Read more about Warren Janssen's replacement confirmed at USCIS Cd. Juarez.
