1. 每周工作是20小时以上就可以吗？ 我看到USCIS网上有这么一句话读不太懂，能帮
忙解释下吗？
Students on an OPT STEM extension are allowed to volunteer, incidental to
their status. This means that volunteer work is allowed but does not count
as employment for the purpose of maintaining F-1 status.
2. 看到有的版友说volunteer只能给non-profit做，一般的公司不能做volunteer？
3. 如果找到一个跟专业不太相关的公司，但是做一个专业对口的职位，比如程序员，
这样可以吗？
多谢大家帮助！
