回复：谢谢, 博士后可以申请E1A 吗?回复：你罗里罗索的苦经我很同情,

Yes. Postdoc absolutely can apply for green card under EB1A item, and do not need employer support letter. I think you have a very good chance based on your background. You may find a good lawyer to handle this matter. By the way, leave that Chinese boss if possible. It is not difficult to find a postdoc position, right?
