是不是大使馆发信让交护照就说明签证批准了？

我是7月2号在美国驻新加坡大使馆面签的H1B，不幸被check，当时签证官也没收我的护照。等了两个多月之后终于在9月5号update了，当天下午就收到大使馆的电子邮件让交护照。邮件如下：

1. Dear U.S. Visa applicant, The administrative processing on your U.S. visa application has been completed.  Please dropyour passport off at the Aramex courier office with the green document submission cover letter you were given at your interview.  If you did not receive a green letter or no longer have it, you may print out the attached form and use it to drop off your passport at one of the two Aramex courier offices listed.  You will receive your passport back within 3-4 business days at the address you indicated when you first applied.  Please log in to our website with your user name and password for more information about your passport collection or delivery information at http://www.ustraveldocs.com/sg.   You are strongly encouraged to bring your passport to the Aramex courier office as soon as possible.  The clearance is valid at the time of this message, but our records change on a daily basis.  Your prompt submission of your passport will decrease the chances of further delays in your visa issuance.

我的护照当天下午就交到那个快递公司了，但是目前网上的状态还是和先前的update状态一样，并没有说issue了。请教我这种情况是不是使馆已经批准visa申请了？还是会有别的变数？谢谢！

几乎、肯定、是的！
