美国方面的证明材料，主要是说明日期上需要加急。
没有特别的加急面谈的签证官，里面几个老外都会给你处理的，碰到谁都可以的。比如你约的是 10点的面谈，就10点和他们一起排队就行了。老外面前的电脑都有你的资料，一看你是加急地就会问你去那里去干什么，为什么要加急。你这个时候把证明文件和他说，然后再说明一下。
敬爱的x老师：
您好！
在这金风送爽的季节里，我们又将迎来一个美好的节日——教师节。我首先要祝您节日快乐，工作顺利！趁此机会，我——昔日的“刘阿斗”禁不住要跟你说几句心里话。
老师，我坦率地承认，我不是您喜欢的好学生。您曾经不止一次耐心地给我辅导，但是我却一次又一次地让您失望，成为您心目中那个扶不起的刘阿斗。
还记得上学期期中时发生的事吧！那天正好是期中考试，我因为前一天在外婆家做客，第二天当我来到教室门口时，同学们已经在考试了。
我站在门口，喊了好几声“报告”后，你才冷冷地示意我进去，可能是因为紧张吧！考试考好后，我居然忘记了写名字。第二天一早，你就在同学们的面前公开地批评我，我知道自己是一个马虎的人，应该受到批评，但是当时您的哪些刻薄的话语，真令我感到无比羞愧，假如地上有道缝的话，我真恨不得钻进去。
那次，我也从您的目光中看到了您没有说出来的一句话——你这个笨蛋！
在以后的半个学期中，我也试着努力改变自己，但不管我怎么努力，换来的都是您的冷眼。有时候我向您请教问题，您也总是爱理不理的样子，好几次我都胆怯地回到座位上。
看着您为其他同学耐心地解答问题，向他们投去慈祥的目光时，我心里别提有多难受了……
老师，新学期又开始了，对于其他同学来说，又将为新的目标努力学习了，而我！已经对学习丧失了信心。我多么希望您，能用一滴甘露来滋润我干渴的心田。
老师，我已经亲手做了一张贺卡，教师的那天，我将悄悄地放到您的办公桌上……
此致
敬礼！（记得要写名，还有要改改！）
还有：（短篇）
尊敬的X老师：
您好！
在二年级那年到现在你总是不断的教我知识，如果我病了，你总是很关心的问我有没有事。
老师您对每一个学生都会很关心，老师你不怕辛苦日夜操劳，早上您要教我们知识，到了夜晚您又要为我们批改作业还有试卷。但是不知为什么，我总是您有时和蔼，有时很凶。在我们班里大多数同学都觉得你很凶，但是我知道大家不会因为这样而讨厌您，而是很喜欢您！我知道其他同学可能是怕您骂他们才说您很凶，还有很多同学觉得您很和蔼，很亲切。
在课堂上您是我们的老师，可是在课余时您是我们的朋友。您是我们永远的老师，您教的知识我们会终生受用。
祝X老师您：
永远开心！
永远快乐
