我再细说一下：
我周末给中文学校摄影club上一小时课，1099 税表 上是 ”nonemployee compensation“
-Non-employee compsensation means some kind of compsensation such as for food, travel cost (e.g. hotel, airticket), etc. occasionally conducting some kind of activity such as speaking, academic meeting/communication,, etc. If so, you will be OK.
真的可以不记入180天违例的范畴？那这算什么？
中文学校说，一般老师算contractor，那不就又是违例？
-Then, this will be a problem. That is employed.
不过我这个解释成hobby 和讲义费，不知可排出违例？
-The problem is you get paid regularly and it may be difficult to justify it. For 100% safety, you had better go out to get the visa to come back. Up to you, anyway.
