Practical Training is work authorization issued by the INS, through the International Student Advisor at the foreign student’s university. There are two kinds of Practical Training: Pre-Completion- which is taken prior to completing the course of studies, and Post Completion – which may be taken only after graduation or completion of all course work in certain cases. The International Student Advisor will issue the necessary approval on form I-20 for both Pre- and Post-Completion practical training. The student then applies to the INS and is issued an Employment Authorization Document, or EAD, on form I-688. Co-Curricular, or Co-Op Practical Training may also be available.
