在给我的e'mail里面说的一些关于check的情况：

Hello Freeking,

Thank you for this e-mail. Let me help you understand the process. When a consular officer sends off for a security check, it is a good thing.
If your application was going to be denied - they would have denied you a visa at the interview (instead of conducting the check). The advisory opinion
means that they support you coming to the US as a student, but they must go through the security check. As long as the security check finds nothing
abnormal about your background, you will get a visa.

The security checks are triggered by a number of factors, including: field of study/research (certain engineering specialties can be considered
potentially dangerous); applicant's name (it may be similar to someone the US government recognizes as a criminal);and nationality.Given the range of issues
inherent to these potential triggers, the security checks are a standard procedure in reviewing visa applicants across the globe.

Of course, the issue that understandably makes you anxious is the time it takes to get the security check completed (so that you can get the visa
stamp and come to the US for your studies). This is the hard thing to predict. As I understand it, the status (and timing) of the check is not something
that they share.

In my experience, security checks (especially for Chinese citizens) rarely take less than a month. Your interview was only on May 15th. If you have
not heard back from the US consulate in Shanghai by JUNE 26th, please e-mail e directly and I will call on your behalf. Until then, intervention
would be considered premature.

As the semester begins at the end of August, there is still time, so try not to worry.

Thank you!

签证小常识:
互免签证：免签证是随着国际关系和各国旅游事业的不断发展，为便利各国公民之间的友好往来而发展起来的，是根据两国间外交部签署的协议，双方公民持有效的本国护照可自由出入对方的国境，而不必办理签证。互免签证有全部互免和部分互免之分。
