I believe someone's been messing with my identity, having access to my Social Security Number and driver's license. The thing is, I'm an undocumented immigrant—I came here legally, but my visa's expired now. I'm scared to report this identity theft to the police. I did call Experian to set up a Fraud Alert, but I'm not sure if that's sufficient. I read that an identity theft lawyer can help dispute these issues. But I'm not sure if I can do anything about it with my expired documents. What should I do?
