Looks like Ciudad Juarez (https://mx.usembassy.gov/visas/family-based-immigration/fb-apply-step1/)
The U.S. Consulate General in Ciudad Juarez has limited authority from the Department of Homeland Security (DHS) to accept certain I-130, I-360, and I-600 petitions. This authority only extends to U.S. citizens filing petitions for Immediate Relatives and to self-petitioning widows.
DHS is normally responsible for adjudicating these petitions and only permits the Consulate General to accept petitions in narrow circumstances.
The applicant and petitioner must meet specific physical presence requirements in Mexico and have authority to remain in Mexico for the duration of consular processing. Petitioners must also show exceptional circumstances, which can include adoption, short notice of job relocation, U.S. military emergencies, or beneficiaries who are close to aging out of visa eligibility. Petitioners should be prepared to provide documentary evidence supporting the basis for local filing. USCIS has published guidance on circumstances that may qualify as exceptional and more information can be found in the Foreign Affairs Manual . Petitioners may not locally file at the Consulate General to circumvent DHS processing times.
Individuals who believe they qualify to file a petition at the Consulate General may contact CDJFilePetition@state.gov to request more information.
