S2 Q&A I already have an I-20 from another school - should I use that for my COS or wait for yours?

 That's a real decision and it's the senior consultant's, not mine - it turns on your grace-period end date, which school can issue an I-20 in time, and where you actually want to study. What I can do today: get you an admission and I-20 from a partner fast enough to keep both options open, so you choose with two I-20s in hand instead of one. When does your grace period end?
