What kind of trouble can a person get in if they marry an alien for money just so he can get citizenship?

Marrying an alien for money to facilitate citizenship can lead to serious legal consequences, including charges of Immigration fraud or marriage fraud. Such actions can result in fines, imprisonment, and the possibility of deportation for the alien involved. Additionally, the U.S. Citizenship and Immigration Services (USCIS) may deny the application for citizenship, and it could impact future immigration benefits for both parties. Engaging in this kind of arrangement undermines the integrity of the immigration system and can have lasting repercussions.
