CHI wants you to be cautiously aware that there are thieves who are targeting international students through a phone scam. The caller will claim to be from the Department of State, Customs and Border Protection, or the Internal Revenue Service (IRS), and will instruct you to pay them money due to missing visa forms, improper tax filings, etc.
Also, they may provide a badge number trying to make the call seem legitimate, and may even threaten that if you hang up, turn off your phone or even leave your house without depositing money into their accounts, you could be arrested.
Please trust that this is a scam. Do not send them money. Hang up the phone immediately, and contact CHI right away at : 1-800-432-4643.
