美国留学：最易移民的STEM专业解析

　　伴随着中国经济和互联网的发展，‘留学’这件事情似乎也越来越揭开了她神秘的面纱，它变得不再那么遥不可及。越来越多的‘90后’对自己留学之路的规划也更加理性。他们不再是一味追求所谓的热门专业，反而开始寻找自己真正喜欢的，或者跟自己的人生规划相结合的留学专业。这也是属于‘90后’自己的特征，他们有主见、有想法，也越来越知道自己需要什么。在他们眼里，留学不仅仅是留学，更是移民国外的理想途径。（咨询）

　　众所周知，美国是个留学大国，拥有着全球最优秀的教育资源，每年吸纳成千上万的海外留学生。然而，在美国的移民签证政策越来越收紧的状态下，留学生毕业后继续留在美国就变的越来越困难。那今天这篇文章，就来给大家分析下当下最火热的STEM专业，以及怎么好好的利用自己的专业，从而拥有更多的机会留在美国工作，甚至移民。

　　2013年，奥巴马总统提出新的移民政策中一直提到STEM这个词，那STEM到底是什么呢?其实，STEM代表的是四种不同专业的大方向，共包含422个具体的专业(具体专业见文章下面的附录一)。本文就是要解开STEM的神秘面纱。

　　S代表Science科学，T代表Technology科技，E代表Engineering工程，M代表Mathematic数学。如果你的专业属于这一类里面的，你将要获得比别人多17个月的OPT(全称Optional Practical Training，专业实习)时间。OPT计划是美国针对国际留学生颁布的一项政策。根据OPT计划，国际学生从美国大学毕业后，可继续以学生的身份在美国工作实习12个月，但是美国移民海关总署(ICE)规定，科学、技术、工程和数学(即STEM)专业领域内的毕业生OPT时间可延长至29个月。

　　STEM，是美国乃至世界蓬勃崛起的前景学科，相关领域的工作也被认为是未来薪资最高、最有澳际的职业。因此，STEM专业的留学生也享受到比其他专业学生多出150%(一年半)的毕业实习时间。近期有美国专家提出忧虑，认为美国目前在STEM教育上落后于全球其他国家，应该加强对其的重视和投入。

　　根据全球经济论坛提出的数据，美国在教育系统质量上排名全球28，在初等教育质量上排名全球38，在数学和科学教育质量上排名全球47。然而在与STEM相关的工作中，超过70%都与计算机科学有关。STEM专业教育和STEM就业的匹配程度出现了巨大反差。同时，由于美国目前经济状况向下发展，与STEM相关的工作缺口非常巨大，已经达到了3700万。社会市场基金会(The Social Market Foundation)的报告表示，由于劳动大军的老龄化问题，每年将会有10万份需要STEM专业毕业生填补的工作缺口。而根据目前美国在学校中STEM人才的缺失看来，到了2018年，这一人才缺口将达到8600万。倘若那些从事非STEM专业工作的STEM毕业生人数不变，那么在2020年之前每年都需要额外的四万名STEM专业毕业生。

　　STEM的学科性质决定了其自身发展的迅速性。据分析，到了2018年，92%的传统STEM工作将需要工作人员接受中学以上的教育和培训。而目前在高中开始时对STEM感兴趣的美国学生，60%在毕业时失去了兴趣。而那些选择继续在大学进行STEM学习的学生，则展开了在地球与空间科学、物质与能量、生物医学等广阔领域的学习。在毕业后的就职选择上，具有STEM知识背景的学生可以进入如航空工程、人工智能等充满乐趣的领域工作。另外，奥巴马总统已经提议投入800万美元提升STEM教育。所以国际学生在STEM领域具有非常大的发展潜力。

　　那么如此火热并拥有良好前景的专业，毕业后申请OPT的条件又是什么呢?

　　要申请OPT的延期，F-1身份的学生必须：

　　1. 目前已经完成学位，处于12个月的Post-completion OPT状态;

　　2. 已经获得了在科学、技术、工程、数学(Science, technology, engineering, and mathematics)专业的学位。具体包括以下领域：Actuarial science, Computer science, Engineering, Engineering technologies, Biological and biomedical sciences, Mathematics and statistics, Military technologies, Physical sciences, Science technologies, Medical scientist;

　　3. 受雇于美国雇主，在与其专业直接相关的领域内工作;

　　4. 雇主必须参加移民局的E-verify 项目;

　　5. 具有有效的F-1身份(注：OPT仍然属F-1身份) 。

　　预祝有这方面潜质的同学们，抓紧时间找好自己的专业定位，抓住这给力的政策，从而使自己在留美这条道路上越走越宽，越走越好。
