I called Tennis Warehouse a few weeks ago and inquired about how they measure racquet flexibility/stiffness and assign ratings (RA) given that most of the ratings they assign seem to differ from those listed by the actual racquet manufacturers.
What is Optional Practical Training (OPT)? Optional Practical Training (OPT) is the opportunity for an F-1 student to apply knowledge gained in the classroom to a practical work experience. OPT is a work permit allowing F-1 students to work in the U.S. for up to 12 months following graduation in a job related to their major.
An F-1 student may be authorized to participate in pre-completion OPT after he or she has been enrolled for one full academic year. The pre-completion OPT must be directly related to the studentâs major area of study. Students authorized to participate in pre-completion OPT must work part-time while school is in session.
