美国常见敏感专业请参考以下:
信息系统安全专业
该专业与加/密信息系统方面的知识相关,主要是以确保通信、数据、影像,及有关软件的安全。这恰巧对整个国家的安全来说至关重要,所以当地不太愿意将该先进知识传授给他国学生,以免技术被利用。
高级微电子技术专业
推进电脑端与软件在军事导弹系统中的研制力度及部署措施,有利于发展核武器。其技术包含了:空中定位系统与电子抗干扰器等。
远程拍摄/侦查专业
话说遥感科技的确属于冷门专业,但却列为高科技领域范畴。我们大多所知的遥感科技都是给予民用,但有些也可被军事用来完成侦查目的。
材料科技专业
这个专业所涉及的“材料”并非我们普通人使用的那种,而是用于造飞机、航空器及潜水设备的复合型先进材料。这类特殊材料均以用来开发电磁与超导等高科技能力,所以在面签时,签证官会格外保护这类被他们国家列为“重点保护”的专业。
导弹专业
但凡是与飞行器或是导弹系统相关联的专业都会被美国设置为“重点保护”专业,所以就算你申请了,到头来一样会被拒。拿卫星运载火箭这门高科技来讲好了,这其中的技术就包括弹道导弹、太空火箭、飞行器的载入,以及无驾高空设备等。
化学生物工程
这个受到了我国绝大多数理科生的向往和青睐,待完成学业后能够从事高能制药工作,所以该专业听起来很一般,实则也是美国的敏感专业之一,最叫人担心的就是技术被滥用制作危险化学品。
飞机和导弹的推进及运载专业
该专业的技术知识与飞机与导弹的近地面超速飞行相关,有很多类似技术都具有多重作用,包括液体/固体火箭的推进技术、航天耐热组织及推进设施等技术。诸如此类的科技全都属于国家保护的机密,即便是在我国,也难以被人接触到,更别说美国社会了。
希望回答对你有帮助,望采纳。

很多人在签证时候都会碰到check的情况,尤其是针对一些敏感专业,很容易就被check了,因此对于这些敏感专业,在签证的时候要尽量淡化,或者想好说明和做好被check的心理准备。Julie老师这次被行政审查估计就是因为专业吧,chemical engineering。。。。。
下面是比较全面的美国留学敏感专业列表。
