You must:

• Request that your designated school official (DSO) at your academic institution recommend the OPT.

• 
  
• Properly file Form I-765, Application for Employment Authorization with USCIS, accompanied by the required fee and the supporting documentation as described in the form instructions.
• 
  
• OPT employment must be related to your field of study and can include paid employment, multiple employers, short-term gigs, self-employment, and unpaid internships.
