There are many types of immigration fraud, but they can generally be divided into two categories:

1. Fraudulent documentation: This occurs when someone provides false or fraudulent documents to immigration officials to gain immigration benefits. For example, someone might submit a fake diploma or work certificate supporting their immigration application.
2. Misrepresentation: This occurs when someone provides false or misleading information to immigration officials in order to gain immigration benefits. For example, someone might lie about their name, age, or criminal history on their immigration application.

Both fraudulent documentation and misrepresentation are serious forms of immigration fraud that can have significant legal consequences. Suppose you suspect that someone has committed immigration fraud or misrepresentation. In that case, it’s important to report the situation to the appropriate authorities, such as U.S. Citizenship and Immigration Services or the Department of Homeland Security.
