Removal proceedings are legal actions initiated by the U.S. Department of Homeland Security (DHS) or the U.S. Attorney General's office to remove an individual from the United States due to alleged violations of immigration laws. Form I-539 does not apply to individuals who are in removal proceedings or have received a Notice to Appear (NTA) in immigration court. If you are in removal proceedings, you should consult with an immigration attorney for guidance on your specific situation.
