IRS Review: You are required to keep a Form W-4 on file for each employee for at least four years after the date the employment tax becomes due or is paid (whichever is later). When requested, you must make original Forms W-4 available for inspection by an IRS employee. You may also be asked to send copies of certain Forms W-4 to the IRS.

Can J2 transfer to H1 without waver? Thanks.
因为雇佣人的时候没有要雇员签W4就是违法了（不一定犯罪，但是违法有罚款）
如果签字的时间是现在，楼主不是雇员为i什么要签字？难道不是作假？
如果签字的时间是两年前，W4也是2018年的W4，那么就是作假
。。。觉得有点麻烦了，算了吧，光补w4没用处。
