对于H1知之甚浅，

1。请问什么样的工作可以申请H1？学校OFFER的半年期以上的可以马上申请H1吗？

=> many different kind of jobs. The employer has to be willing to sponsor you and the wage should be in the right range.

2。不用OPT就可以直接申请H1吗？

=> yes

在第一个工作中申请完H1以后，如果再换工作，那还可以起用没有用过的OPT吗？

=> this is a tricky quesiton. opt is for temporary working right after graduation. if u already graduate and work for some time, I don't think the international student office will help you to get opt(check with ur school).

3。Master还没有毕业（估计得等到8月以后），这个时候能以学校的工作申请H1吗？想边工作边慢慢完成毕业论文，能行吗？

=> yes. u can apply for h1 anytime, as long as the employer is ok with it.

谢谢！
