我是一个H-1B程序员，在一家大型软件公司。现在工作清闲得要命，所以想找一份第二职业。当然还是编程序，就可以在家工作。现在的问题是有没有可能不让我现在的雇主知道。不知各位是不是有这方面的经验。
我查了一下移民局的网站，在Q＆A里写着
Who can an H-1B alien work for?
H-1B aliens may only work for the petitioning U.S. employer and only in the H-1B activities described in the petition. The petitioning U.S. employer may place the H-1B worker on the worksite of another employer if all applicable rules (e.g., Department of Labor rules) are followed. H-1B aliens may work for more than one U.S. employer, but must have a Form I-129 petition approved by each employer.
各位看看最后一句话是什么意思，难道我还让我现在的雇主在129表上签字不成？
如果以上合法的途径不能成功，还有别的什么办法吗？
