那么cap the gap是自动的，
-Yes a slong as the H1 is filed.
还是需要去原来的学校重新extend一下I20，
-Yes. You need to provide a copy of the h1 petition receipt whcih show you are the H1 beneficial to the International student Office and get a new I-20 to extend your F1 to Oct. 1. Although Cap to Gap extension is automatically granted by law, the SEVIS will not automatically show this information. So, you still need the International Office to put your Cap-Gap extension record to the SEVIS.
如果要经过学校，学校问起有没有申绿卡，会不给延I20吗？
-GC application has nothing to do with the school, so normally they will not ask this kidn of question.
