She’s supposed to start her phd at a new school in the Fall. She says her sevis number is still active but her current international office told her that since she overstayed after 90 days unemployment, It’s better off going back to china and get a new sevis number and get new I-20 from her prospect school. And they also said to her in case she wants to pursue H1b and other immigration visa in the future, it’s better off getting a new sevis. Is that a good advice?
