EB1- Green Card eligibility

Hi -
I am on H1b visa and have 2.5 yrs remaining and recently promoted to Techical Architect- equivalent of Project Manager Role but technical role.

My employer Plans to send me out of US for 1 yr.
Will I be eligible for Eb1 category?

Also If my employer files in Eb2 now can it be converted to eb1 while I am outside the US
