Since 2013, Homan has been executive associate director of ICE Enforcement and Removal Operations (ERO). Homan is a 33-year veteran of law enforcement and has nearly 30 years of immigration enforcement experience, according to the release.

He led ICE's efforts "to identify, arrest, detain, and remove illegal aliens, including those who present a danger to national security or are a risk to public safety, as well as those who enter the United States illegally or otherwise undermine the integrity of our immigration laws and our border control efforts," according to the release.

It’s a reunion the Naji-Talakar family looks forward to every year. Marzieh Moosavizaveh lives in Iran, but has been visiting her family in Phoenix since 1993. “Every time Grandma comes to visit I go escort her from the international terminal to the Southwest terminal, but this time around she didn’t come out,” Marzieh’s grandson Siavosh said. Completely unaware of the executive order Donald Trump signed during her 19-hour flight to LAX, Marzieh handed her passport to a customs agent like she always does. Usually the process takes a few minutes, but this time turned into 10 hours. She was detained along with several other Iranian citizens at LAX.
