I am petitioning a family of five with the I-134A. Went into the USCIS office today and submitted biometrics (it's a new process, apparently). They had to take a bunch of photos and a bunch of fingerprints. 3 of 5 cases updated the same time indicating that USCIS is now actively processing them. Cases were submitted July 26, 2024. I previously applied for 8-9 U4U I-134As. This is looking promising for my beneficiaries, I think. It seems like they're doing the biometrics to limit the amount of U4Us that can come, since USCIS offices can only schedule so many biometric appointments.
