Deportation or removal can be initiated against non-citizens for various reasons including, but not limited to:

• Illegal entry: Entering the U.S. without proper authorization or inspection.
• Visa violations: Overstaying a visa or violating the terms of a visa.
• Criminal convictions: Committing crimes considered grounds for deportation, such as aggravated felonies or crimes involving moral turpitude. This category includes serious crimes like drug trafficking, murder, fraud, and certain theft or violent offenses.
• Failure to update address: Non-citizens must inform USCIS of address changes within 10 days. Failure to comply can be grounds for removal.
• Public charge: If a non-citizen becomes dependent on government assistance for support due to a lack of means to provide for themselves, they can be deemed a “public charge” and subject to deportation.
• Fraudulent marriage: Marriages entered into to evade U.S. Civil laws are considered fraudulent and can lead to deportation.
• Security and related grounds: These include activities that threaten the security of the United States, such as involvement in terrorist activities or espionage.
• Unlawful voting: Non-citizens who vote in elections that require participants to be U.S. citizens can be deported.
