我9月1日是F1的OPT，我的OPT時間是2012年8月31日結束。我準備向老板提出申請H簽證，我想問，如果我的H簽證批下來，H簽證的開始時間是從批準之日開始算？（我知道H簽證2－4個月審批時間）還是從我OPT結束的時間開始算（即2012年9月1日），非常不懂，向老師請教。
-It is counted from the start date your employer indicated on the Form I-129 when your H1 petition is approved.
For example, your employer indicated Oct. 20, 2011 as the H1 start date in the Form 129 and the H1 petition is approved on December 20, 2011. Then, your H1 status will be counted from Oct. 20, 2011. But before December 20, 2011, your status is still F1 because your H1 is still pending before that date. Hope I have address it clearly.
