Guys need information to change the status from H1B to F1. Its very urgent. Please give me detail process

 First of all find college for enrollment

You need current Pay stub I mean if you are going to apply this month i.e oct 20 than u need up to september pay stu
 
your H1 approvoal document 

• Form I-539
  
• (fee) personal check or money order payable to DHS
• Original I-20 issued by University
• Form I-94 copy or original (please also include I-797A, Notice of Action)
• I-134 form with your sponsor’s bank statement or letter
• SEVIS fee  receipt
• Personal statement explaining why you would like to change the status
• Copy of passport and visa
• pay stub may required but it depends on DHS officer (in my case they didn't ask)
