请教各位，查到关于I-9的资讯说法不一
目前已经找到full-time unpaid job
(1) Full-time unpadi job算是volunteer没错吧？
(2) 学校international office的文件上写说要填I-9，
但USCIS I-9 instruction我的解读是unpaid job不用填，
究竟要不要填？
USCIS I-9 instruction原文如下: https://www.uscis.gov/i-9
Both employers and employees are responsible for completing
their respective sections of Form I-9.
For the purpose of completing this form,
the term “employer” means all employers,
including those recruiters and referrers
for a fee who are agricultural associations,
agricultural employers, or farm labor contractors,
as defined in section 3 of the Migrant and Seasonal
Agricultural Worker Protection Act,
Public Law 97-470 (29 U.S.C. 1802).
An “employee” is a person who performs labor or services
in the United States for an employer in return for wages
or other remuneration. The term “Employee” does not include
those who do not receive any form of remuneration (volunteers),
independent contractors or those engaged in certain casual
domestic employment.
(3) 因为没有薪水，所以不用填W-4对吧？
谢谢！
