USCIS Form I-539 (Status Extension/Change) — Full Explanation
File before the current authorised stay expires. Applicants receive a receipt notice (I-797C) as proof of timely filing. Multiple family members in the same household may be included on one I-539. Changing from B-2 to F-1 via I-539 is possible but requires demonstrating you did not misrepresent intent at the port of entry.
