申请出国留学需要经过无数道关卡，其中签证是较难逾越的一道。签证申请一旦被拒绝，就意味着之前的努力全部付诸东流。怎么样才能顺利获签呢?
一. 核心问题/ 出国目的问题/ 身份问题
无论是学生签证中的自费还是全奖，甚至于交流学者，这都是签证中最重要的地方。签证官需要确认你的身份，确认你去那边是学习或者是做研究，而不是由其他的任何不良意图。以学生签证为例，在回答问难题的过程中都要体现出我是一个学生，我出去是为了学习，并没有其他的目的。在这里我们建议签证者用专业的入手点，让签证官看到你热爱你的专业，你是一个有理想有抱负的人，并以此博得签证官的好感。如果在回答相关问题的时候表现得非常出色有可能签证官都不会考察你的资金以及归国计划。毕竟美国人是希望有能力有理想的人成为美国公民并未美国创造价值的。记得当年唐师曾去美国的时候，在签证的时候就是出示了与阿拉法特、拉宾、卡扎菲等中东巨头的合影时，签证官给他说美国人民欢迎英雄

二. 资金问题
这部分问题主要会集中在那些自费的学生身上。因为是自费留学，所以一方面需要你通过资金证明来证明在现金上你是有能力支付你未来几年学习的资金的。另一方面通过学生或学生家长的工作来解释我家的钱来源合理，不是借来的，同时也不是非法所得。并且在未来也会有一个很稳定的经济后盾。同时也可以通过其他辅助性的材料来告诉签证官，我并不是把我家里所有的钱都花光了，我家里还有其他的财产。
1. What do your parents do?
2. How do you support yourself during your studies in the United States?
3. Who will be your sponsor? How much is his annul income and what will be the amount you will receive annually? Do you have a bank deposit certification?
4. Have you any bank deposit?
三. 归国计划
签证官会非常重视这点的考察。你一旦去了美国，会不会回来。因为这个是一个比较虚的点，所以在考察的时候，签证官更注重你的家庭约束力，社会约束力，以及你投资去学习的一个必要性，一个投资回报比。当然一切要合乎逻辑。
1. What is your plan? What will you do after graduation? Why?
2. Do you want your wife to go with you?
3. Do you have any relatives in the United States?
4. How much do you earn now? How much will you earn when you come back?
以上就是美国留学签证申请的难点所在，解决了以上的问题，顺利获签也不在是难题了。
