EB-1B Outstanding Researcher, Professor FAQs

How does EB-1C portability work?

I also have a question about the EB1C portability of the priority date. Say, If I have I-140 approved under EB1C and have a particular priority date. For some reason, if I need to or want to change employers and I do not qualify for EB1C with other employers. My new employer can file I-140 under EB-2, or I can file EB-2 NIW myself. I have both options. The question is whether I can use the priority date of the earlier approved I-140 petition under EB1C to the new employer's EB-2 petition and file AOS.
 

Are they changing the law for EB-1? What is the change?

I'm a researcher at a university and I will probably try to apply for EB1, Outstanding Researcher. I'm currently on an H-1 (since Oct. 2007). Are there certain stages in the process in which I won't be able to travel outside the US?

I have my EB2 approved by the USCIS, do I still get the chance to be denied by the US embassy for the consular interview?
