回复：请问可以申请两个H1B吗？

如果有两个公司先后给同一个人申请H1B，这个可以吗？

-Yes, but it is not good at all to ask two employers to file two H1 petitions for you because you waste one of the employers a lot of money and time and thus, it will hurt that employer.

怎么决定哪个生效？

-Both are valid and you can work for either of them.

谢谢。
