有申请Architechtural Engineering 的同学吗

有没有申请Architechtural Engineering 的同学啊， 问个白痴问题，他们截止日期是多少啊？
学院网站上写的是 International students need considerable lead time for all of the paperwork to clear. Therefore, completed applications from international students need to arrive at least four months prior to the expected start date.
这么含糊的写法到底什么意思啊
