USCIS Form I-539

USCIS Form I-539 is a petition form used by nonimmigrants in the United States to apply for an extension of their stay or to change their visa status. This includes individuals on tourist, student, or exchange visitor visas who wish to remain longer or switch to a different nonimmigrant classification. The form requires personal information, details about the current visa status, and the reasons for the requested extension or change. It's essential for individuals needing to extend their stay or pursue a different nonimmigrant category while in the U.S. to properly file this form with the USCIS.
