Tae Heung "Will" Kim, a 40-year-old Korean American legal permanent resident and Ph.D. candidate at Texas A&M University, was detained by CBP at San Francisco Airport on July 21, 2025, upon returning from South Korea after attending his brother's wedding. He was held without access to legal counsel for more than a week and subsequently transferred to detention facilities in Arizona and Texas. The government initiated deportation proceedings based on a sealed 2011 misdemeanor marijuana conviction that Kim had completed and legally resolved. During detention, Kim was denied access to his asthma medication.
