EB-1B--3 years of teaching experience?

I heard that you need at least 3 years of teaching experience in order to file under EB-1B. Is this true? I thought that this was just my university's policy. I'm working as an assistant professor tenure-track at a prestigious university.

yeah it is a requirement for EB-1B. But I think that the teaching experience during PhD can also be counted in the three years. I didn't have an issue with this when I applied for EB-1B and I am also an assistant professor.

to jane.mitchelle930:

If you are applying EB1B as an "outstanding professor", then yes, you need at least 3 years of teaching experience.

I filed my EB1B as a researcher, not professor, but it also requires at least 3 years of research experience.
