據(jù)相關了解，2014年下半年在媒體上炒的沸沸揚揚的奧巴馬新移民改革中總是涉及到STEM專業(yè)這個概念。STEM專業(yè)為科學、技術、工程和數(shù)學專業(yè)的統(tǒng)稱，那么究竟哪些專業(yè)算是STEM專業(yè)呢？接下來就請美嘉導師為大家具體介紹下讓你一次性了解422個STEM專業(yè)：

STEM專業(yè)是什么？它是怎么樣可以讓留學生在畢業(yè)和可以從12個月的實習，工作時間，變成29個月？有哪些專業(yè)是STEM major? 下文為你一一解釋。

OPT(全稱Optional Practical Training，專業(yè)實習)計劃是美國針對國際留學生頒布的一項政策，根據(jù)OPT計劃，國際學生從美國大學畢業(yè)后，可繼續(xù)以學生的身份在美國工作實習12個月，但是美國移民海關總署(ICE)規(guī)定，科學、技術、工程和數(shù)學(即STEM)專業(yè)領域內的畢業(yè)生OPT時間可延長至29個月。

由此理工科（STEM）國際學生在OPT期間，可有充裕的時間申請工作簽證，轉換移民身份。
