Unfortunately international students and scholars are sometimes targeted by individuals attempting to scam or defraud you.
A few ways to identify a phone scam:
The caller ID will be a phone number that looks like it is coming from a government agency or law enforcement/police.
The caller will claim that you owe money or have committed some kind of offense or crime and may use threats or intimidation to get you to do what they want you to do.
The caller will try and keep you on the phone.
It is important to know that government agency and law enforcement officials will never call you to ask for money over the phone. If you receive a suspicious call, contact Safety & Security. Below are important resources for more information:
