打算十月去一家新公司，原公司规定离职的3个月之内必须把ISO股票处理掉，我的ISO股票最远的vest date也只是12/5/2020，也就是说还不满持有(ISOs require a vesting period of at least two years and a holding period of more than one year before they can be sold. ISOs often have more favorable tax treatment on profits than other types of employee stock purchase plans.) 这样的一个规定，请问我可以销售股票吗？还是说这部分股票就会消失了？如果卖股票，这个税是不是算作我的工资了？感谢为先！
