您好，如果您的H1B还在pending期间，那么您就是Cap-Gap OPT的阶段。如果您的雇主因为您的离职撤销了您的H1B申请，那么从撤销日开始，您有60天的grace period准备离境。
移民局官方要求是：If an H-1B petition filed on behalf of an F-1 student covered by Cap-Gap is denied, rejected, revoked, or withdrawn, the student will have the standard 60-day grace period (from the date of the notification of the denial, rejection, revocation, or withdrawal of the petition) to prepare for and depart the United States.
