According to ABC news, ICE agents in Koreatown, California came in and verified that the cashier had a valid green card and served notice on the owner to produce hiring records in three days to check employees' immigration status.

GONZALES: For its part, Irving, Texas-based 7-Eleven said in an emailed statement that its franchisees are independent business owners and exclusively responsible for who they hire and verifying who is eligible to work.
