It may be possible to apply for a 签证 在一个 U.S. consulate in a country other than your home country. 这被称为“third country national (TCN)“应用程序. 不是所有的人.S. consulates accept TCN applications, and some allow TCN applications for limited situations; check with individual consulates, including those in Canada and Mexico, for TCN application policies.

英语
预计面试将用英语进行，而不是用你的母语. 一个建议是在面试前和以英语为母语的人练习英语会话, but do not prepare speeches! 如果你来美国只是为了学习强化英语, 准备好解释英语在你的祖国是如何有用的.
为你自己说话
Do not bring parents or 家庭 members with you to the interview. The consular officer wants to interview you, not your 家庭. 如果你不准备为自己说话，就会给人留下负面印象. 如果你是一个申请高中课程的未成年人，需要你的父母在那里以防有问题, 比如资金, they should wait in the waiting room.
KNOW THE PROGRAM AND HOW IT FITS YOUR CAREER PLANS

是短暂的
Because of the volume of applications received, 所有领事官员都在相当大的时间压力下进行快速有效的面谈. They must make a decision, 在很大程度上, on the impressions they form during the first minute of the interview. 因此，你的开场白和你给人的第一印象对你的成功至关重要. Keep your answers to the officer's questions short and to the point.
附加的文档
领事官员应该立即清楚你所提交的书面文件以及它们的含义. Lengthy written explanations cannot be quickly read or evaluated. Remember that you will only have 2-3 minutes of interview time.
NOT ALL COUNTRIES ARE EQUAL
申请人来自遭受经济问题的国家或许多学生留在美国的国家.S. as immigrants will have more difficulty getting 签证s. 从统计数据来看，来自这些国家的申请人更有可能是有意移民. 他们也更有可能被问及在美国学习后在国内的工作机会.S.
就业
Your main purpose in coming to the United States should be to study, not for the chance to work before or after graduation. While many students do work off-campus during their studies, 这种工作是附带的，他们的主要目的是完成他们的美国.S. 教育. 你必须能够清楚地表达你在课程结束后回国的计划. If your spouse is also applying for an accompanying F-2 签证, be aware that F-2 dependents cannot, 在任何情况下, 在美国工作.S. 如果被问到，准备好回答你的配偶在美国期间打算做些什么.S. 志愿工作和兼职上学是允许的活动.
DEPENDENTS REMAINING AT HOME
If your spouse and children are remaining behind in your country, 准备好说明在你离开的时候他们将如何养活自己. 如果你是家庭的主要收入来源，这可能是一个特别棘手的领域. 如果领事官员认为你的家人需要你从美国汇款来维持他们的生活, your student 签证 application will almost certainly be denied. If your 家庭 does decide to join you 在一个 later time, 让他们在你申请签证的同一岗位申请是很有帮助的.
MAINTAIN A POSITIVE ATTITUDE
Do not engage the consular officer in an argument. If you are denied a student 签证, 向签证官要一份他或她建议你携带的文件清单，以克服拒绝, and try to get the reason you were denied in writing.
