去国外留学首先是语言上的问题，即使你在中国外语学的再好，真正去了国外也会不适应，因为口音和语言习惯都会和你在中国学的有出入。
然后生活上需要完全自理，如果你本身就可以照顾好自己就没有什么问题了，但是凡事都要自己考虑，自己拿主意，没有可以依靠的人。
人际关系方面会相对比较复杂，不要轻易相信别人，我自己在国外读书的时候就因为轻易相信人吃了不少亏。不要轻易透露自己的资产，钱财不外露这点非常重要。
有时候会觉得很孤单，这个要靠自己去克服。
遇到困难的时候没有人会安慰你，也许你可以在国外找到很好的朋友，但是总是会觉得有隔阂。
跟当地人会有隔阂，无论你语言学的再好，生活习惯，思维方式的不一样，会导致跟当地社会难以融合。

申请美国留学有哪些易错点？

第一，在书写文书的时候写上你的考试成绩。事实上，院校已经通过你或者你的高中寄出的资料了解了你的考试成绩。
The first mistake is when asked to write an essay, you write about your test scores. The college already knows your test scores that were sent in by you or your high school.

第二，寄送了过多的补充材料。中国学生寄送从一年级以来获得的证书、奖项、还有证书的复印版本。相信你很骄傲你所获得的证书，确实，你非常努力参加了很多比赛才赢得这么多的奖项。但问题是每个申请美国大学的中国学生都寄送很多没有被要求的材料。阅读这些材料反而阻碍了对学生的评估。如果你没有寄送额外的材料却清楚地表现出你想做什么，你将会从你的同学们中脱颖而出。
The second most common mistake is sending too many supplementary materials. Chinese students send certificates, prizes, and copies of certificates that they have earned since first grade. You are very proud of your certificates, and rightly so, you have worked very hard for them with an enormous amount of competition to get those prizes. The problem is that every Chinese student who applies to college sends too many materials that are not requested. All of those things to read get in the way of evaluating the student. You will stand out among your classmates if you do not send extra materials and standing out is what you want to do.

第三，很多中国学生会提交给招生官一个封皮上印着他们照片的小册子或者一本书，用照片和文字故事去描述自己的生活。这些册子其实是浪费时间和钱财的一项工作，在这个世界上没有其他人会寄给他们这些东西，因为学校是不想花时间去浏览这些册子的内容的。
Many Chinese students have a small book or booklet printed with their picture on the cover and a picture and word story of their life for the admissions officer. These booklets are a waste of time and money and no one else in the world sends them because the colleges do not want to spend any time looking at these booklets.

第四，当被要求回答学校申请的问题“为什么你想去宾夕法尼亚大学、戴维森学院或者南加州大学”时，很多中国学生会写这个大学是多么地漂亮，进入这个大学学习是多么大的荣誉。其实这些大学是想了解你，而不是他们已经知道的关于他们大学的东西。他们希望你说出你到底是怎么样的，你喜欢学习什么，你喜欢做什么运动，你喜欢听什么音乐，你有多么了解你申请的学校里的学生到底是什么样的。
When answering the application question, why you want to go to the University of Pennsylvania, or Davidson College, or the University of Southern California (USC) most Chinese students write how beautiful the college is, how much of an honor it would be to go there. The colleges want to learn about you, not what they already know about their college. They want you to talk about who you are, what you like to study, what sports you like to play, what music you like to listen to, and how well you know what the students are like at the colleges where you are applying.

第五，很多中国学生想学习工程或者商业。美国大学不希望录取一个跟其他中国学生很像的学生。就算你真的想成为一个建筑师或者会计师，也要写一些别的你想学的，或者你喜欢读的书，或者你喜欢看的电影。你可以写一些关于中国的东西，例如中国的历史，中国的诗词或者艺术，再或者生活在一个共产主义国家的你的成长历程是什么样子的。也写一些别人不会写的东西，例如你的家庭或者你除了学习以外的工作。
Most Chinese students want to study engineering or business. The American colleges do not want to take students who are like all of the other Chinese students. Even if you do want to become an engineer or an accountant, write about something else that you also like to study. Or books you like to read. Or movies you like to see. Write about something Chinese such as Chinese history, Chinese poetry or art, or what it’s like to grow up in a Communist country. Write something that everyone else isn’t writing about such as your family, or your responsibilities other than studying.原文来源：http://wWw.LiuXue86.Com/a/2288786.html
