回複：回複：Urgent!! Urgent!!!. Pjiang, Xiao Bai Tu, and 8-teacher:

Thank you for your immediate reply, dear 8 Lao Shi:

   This is a school district. 

    I have another question. My PhD is in education. I have used up my 12-month OPT. Can the old university file an OPT extension under such circumstances? Does a new I-20 mean that I need to enroll in one program?

   When you say 'always talk to the school after you get H1 filing receipt', does you mean this hiring institution?

   Thanks a million
