A green card holder can be put into removal proceedings (deportation) and lose their status for a number of reasons, including:

• Abandonment of U.S. Residency: This is one of the most common reasons. Spending an extended period outside of the United States (typically more than 180 days, and especially over one year) without a reentry permit can be seen as abandoning your permanent residence. Failing to file U.S. income taxes while living abroad can also be a factor.
• Criminal Convictions: Committing certain crimes can lead to revocation. These include “aggravated felonies” and “crimes involving moral turpitude” (CIMTs). Examples can include drug trafficking, domestic violence, theft, or fraud.
• Immigration Fraud: If it is found that you committed fraud or misrepresented yourself during the green card application process, your status can be revoked. This includes lying on forms, using fake documents, or entering into a fraudulent marriage solely for immigration purposes.
• National Security Concerns: Engaging in activities that are deemed a threat to national security or associating with a terrorist group can result in immediate revocation of your green card.
• Failure to Remove Conditions: If you have a conditional green card (often granted through a marriage), you must file a petition to remove the conditions before it expires. Failing to do so can lead to the termination of your permanent resident status.

What is the Process?

The revocation of a green card is not an automatic process. If the U.S. government believes a green card holder has violated immigration laws, they will initiate removal proceedings by issuing a Notice to Appear (NTA) in immigration court. The green card holder then has the right to defend themselves before an immigration judge.
