As you know, if your green card is lost or stolen, you may also wonder about identity theft. Identity theft is when an impostor obtains personal information, such as a green card or social security card, to impersonate someone else. With that information, the impostor may obtain new credit cards, make unauthorized purchases, and temporarily ruin your credit score which could be difficult and take time to rebuild. What’s worse, the thief may provide false identification to police, creating a criminal record or leaving outstanding arrest warrants for you, as the victim of the green card identity theft.
