-No. It is still effective.
移民局還會批準我已經遞交的那個H1B 轉 B2的申請嗎?
-Yes, if they think your application is qualified for approval.
或者我可以要求在新雇主給我轉H1 的時候,撤銷我已經遞交的pending的H1B 轉 B2的申請,可以嗎
-The problem is that if you withdraw the B2 application, you are considered out of status during the period of time between you lost job and you find a new job.
