I think i made a mistake in my old post. The old post link is here (LinkForOldPost)
First fo all, I feel sorry to all frineds who have read that old post. I have misunderstood the questions raised by webID "Dang" on the forum and input some misleading information.
Actually EB1-a and NIW can be sponsored by Yourself or Your Employer. What I was trying to emphasize is that if you ask your employer/supervisor to do it for you, you will be bound to work for your employer for certain period of time and lose your freedom when you want to change job in the future.
YourselfYour Employer.
If you have any futher questions, just feel free to contact me and we can discuss about it. Thank you all.
