近日，国际性组织"21所大学联盟"(Universitas 21)在瑞士兰德大学宣布了全球受高等教育最好的国家排名，其中美国居首位。那么在竞争日益激烈的美国留学的队伍中，以商科的竞争最为激烈，很多人不禁要问：“去美国留学，除了读商科，还能读什么？” 答案是理工科，读STEM课程。那么你准备2013年去美国留学读STEM课程了吗？新天空留学美国的老师为你准备了最新的STEM专业，先来看看吧！

　　OPT(全称Optional PrACTical Training，专业实习)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。由此理工科（STEM）国际学生在OPT期间，可有充裕的时间申请工作签证，转换移民身份。

　　2011年5月，ICE对STEM领域的专业适用范围新增了50类，而至2012年，STEM领域专业列表如下：
