J1是8月底到期，加上30天Grace Period, 可以在美國停留至9月底，是嗎？
-Yes.
6月初遞交轉F1申請。（轉身份前已經獲得J1 Waiver批準）
如果到9月底沒有結論，可以繼續在美國等待？
-Yes.
若轉身份通過，但錯過了8月下旬開學，可以在美國呆到學校10月份或12月開學嗎？
-Discuss this with the International Student Office at your school because probably your I-20 needs to be updated to stay in US until October or December for the study if you do not study beginning August.
But you actually can enroll the school in August to study even if the F-1 is pending. Thus, you do not need to worry about when the F-1 is approved.
謝謝8老師百忙中的指導
