Mobile Fortify

Several senators urged ICE to stop using the app for fear of infringing on fourth amendment and first amendment rights, and requested details on who developed the app, when it was deployed, whether the app was tested for accuracy, and policies and practices governing its use. On June 2025, they sent an open letter to Todd Lyons, ICE acting director, signed by senators Cory Booker, Chris Van Hollen, Ed Markey, Bernie Sanders, Adam Schiff, ^[9] Tina Smith, Elizabeth Warren, and Ron Wyden.^[6][10][11] On November 3, a second letter was sent to the ICE by senators, after not receiving answers to questions from the previous letter deadlined for October 2.^[7]

Mobile Fortify, and ICE's use of similar biometric identification technologies (such as Mobile Identify, an app similar to Mobile Fortify to be used by local or regional law enforcement to assist in immigration enforcement ^[12][13]) has faced scrutiny from a variety of digital rights organizations, politicians, and news outlets.^{[14][15][16][17]} The criticism is already considered to potentially be a reason why the similar Mobile Identify app was pulled from the Google Play Store. ^[18][19][20]

Facial recognition technologies are known to produce false-positives and generally unreliable results, especially on those with darker skin tones.^{[21][1][22][23][24][25]} ICE has already previously mistakenly arrested a U.S. citizen under the belief he was illegally in the country, and later stated that he "could be deported based on biometric confirmation of his identity" prior to his release.^[17][26][27]

U.S. representative Bennie Thompson, ranking member of the House Homeland Security Committee has previously commented that "ICE officials have told us that an apparent biometric match by Mobile Fortify is a ‘definitive’ determination of a person’s status and that an ICE officer may ignore evidence of American citizenship—including a birth certificate—if the app says the person is an alien," and that "Mobile Fortify is a dangerous tool in the hands of ICE, and it puts American citizens at risk of detention and even deportation," ^[26][28]

On January 19, 2026, 404 Media reported on a case where a woman, identified in court documents as "MJMA", was scanned by Mobile Fortify twice in the same interaction, and two entirely different names were provided by the app. According to the Innovation Law Lab, whose attorneys are representing MJMA, both of the names were incorrect.^{[29][30][31][32]}

ICE has stated that they will not allow people to decline to be scanned by Mobile Fortify, and that photos taken, even those of U.S. citizens, will be stored for 15 years,^{[33][16][34][35]} something that has been criticized primarily because ICE has not performed a Privacy Impact Assessment (PIA)^[36][37] for Mobile Fortify, the right to decline other forms of biometric verification to the U.S. government is often available under other circumstances,^[38] and the 15 year window is viewed as unnecessarily large.^[15][34]
