You may work for more than one employer on STEM OPT, but each employment occurrence
must be related to your stem STEM field of study, and must be for at least 20 hours
per week. Each separate STEM OPT employer must provide an I-983 Training Plan. If
you have any change of employer, a material change in your employment with the same
employer, or the addition of a new employer, you must submit a new I-983 Training
Plan to the ISSO and must obtain a new STEM OPT authorization on your I-20.
