part-time CPT，规定20小时每周，如果公司需要超时怎么办？

反正只能拿20个小时的钱，要不要超时做就你自己决定拉

ask for more money if you want to go. otherwise just tell them u need to meet professor

more money, or more leave time (you can say I worked 38 hours this week, but only legally for 20 hours, so I will work 2 hour next week.) blah blah blah
