S2 Q&A How long does USCIS typically take to process an H-1B→F-1 (or other) change of status?

  It varies. Regular processing of Form I-539 can take months; with premium processing (an extra USCIS fee - see the current USCIS fee schedule) USCIS acts within 30 business days, about six weeks, once it has everything it needs. Whether you can begin classes while the change is pending depends on your current status: B-1/B-2 visitors cannot enroll until it is approved, and other cases are decided with the school's DSO. Our senior admission consultant maps your dates with you before you file.
