I have a question about CPT and I-20. Both of my CPT and I-20 expires at July 27th. But my non-paid internship want me to work until August. Can I still do the non-paid intern in my grace period? What if they find out I am doing the non-paid internship in grace period? How they going to find out? Can I say I just volunteer after the period but not intern? Thank you very much!
