I am thinking about applying for green card under EB-1A or EB-1B. Currently I have an approved I-140 (2005, EB2). I have a few questions:
Q.a) Is the EB1A or EB1-B I-140 premium processed?
Q.b) Do I need to submit another set of I-485 with the EB-1 application even though the EB-2 I-485 are pending with USCIS?
Q.c) Which option would be better for me - EB-1A or EB-1B? I am currently an associate professor at XXX University.
