诚心求教！
我是2014年5月硕士毕业，今年六月底开始OPT，8月底在一所州立大学找到一份40个小时的全职行政工作。学院想请我当2015年春季学期的汉语教师，教一门汉语课，并且2015年暑期也要教一门汉语课。可是我的工作职责里写得很清楚，只是负责学生汉语的辅导和文化活动，没有写可以教汉语课。如果我要来教这门课，学院需要重新写一份合同吗？
-No, do nothing.
我需要学院怎么做，从而能让我教课（我是很想接受这个工作，而且学院也找不到合适的人选。我不想一直做行政，因为我的专业是外语教学）。但是学院现在的担心是，我在OPT期间，已经是40小时的全职工作， 额外的每周上两个小时的汉语课，会不会超时工作，OPT期间是否只能做一份工作。
-No limit for time and job number. You can work as longer as you can and as many jobs as you can as long as these jobs are related to your major.

How many hours per week can I work?
Pre-completion OPT is limited to 20 hours per week while school is in session and the student still has coursework to complete. Full-time employment can be requested for pre-completion OPT done during official school breaks.
For post-completion OPT, a student must be employed for at least 20 hours per week. Students requesting post-completion OPT may work 40 + hours per week.
因为学院上到院长，下到小秘没有一个人懂得移民法律，整个学校问了一圈也没有专业人士懂这个，特此向大家求教，最好给我一个明确的链接，我可以打印并且标黄给院长看。
