个人认为，校外工作不等同于校外收入，所以完全合理合法，原因如下：

这种survey一般不会给你寄1099表，只要不寄那个表，就不用报税，也就不是work income，F1是不许校外工作，而不是校外收入，你的收入如果不是work得来的，自然没有人管你。

例如你买彩票，中了头奖，这个钱也算校外收入，但是合理合法。

My idea is:

just get the money and leave the rest to later -- unless it is a lot of money.

How much is that for your survey? Is that you fill the survey, or you let others fill the survey?

That's what I was going to say.

我发邮件问了问SURVEY的公司，他们的回复是：

You will only need to pay taxes on earnings if you receive a combined total of $600 or more in checks from us in a calendar year.

可是当我去CASH这个CHECK的时候，银行的记录会显示出来是这个公司PAY我的，is that a problem?

SURVEY的公司是http://www.sendearnings.com，　每天一个　，一个一刀．

As long as you get paid less than $600 in a calendar year

Thanks for sharing that survey site.
