You have to change the job title.回复:我这样的条件可以申请EB1B吗?
You can ask your boss to change the job title to research engineer, or other title you think better. It is the 1st step. If this is done, you have enough for EB1B. You can receive your GC in one year as I learned from this forum.
If your boss is good to you, he may help. Good luck!
