There are many types of immigration fraud, but here are a few common examples:

1. Marriage fraud: This occurs when someone marries a U.S. citizen or permanent resident solely to obtain a green card rather than for genuine love or companionship.
2. False information: This occurs when someone provides false information on their immigration application, such as lying about their name, date of birth, or criminal history.
3. Document fraud occurs when someone submits false documents, such as a fake diploma or work certificate, in support of their immigration application.
4. Asylum fraud: This occurs when someone falsely claims to be a victim of persecution or torture to gain asylum in the United States.
5. Investment fraud occurs when someone invests money in a business or project in exchange for a promised green card, but the investment is fraudulent or does not meet the requirements for an EB-5 visa.
6. Immigration consultant fraud occurs when an unlicensed individual provides immigration-related services for a fee, even though they are not authorized to do so.

These are just a few examples of immigration fraud, and there are many other ways in which people can commit fraud or misrepresentation to gain immigration benefits. It’s important to be aware of the signs of fraud and to report any suspicious activity to the appropriate authorities.
