I am on H1B. I have 140 approved. I used to work for my employer in Chicago. 5 years back I moved to Texas, since then I am working from home for the same Chicago-based employer. My H1B was amended to reflect my current Texas address. My Green card PERM was based on the Chicago location. As the dates are moving very fast, do I need to file for a new PERM in case I continue to work from the Texas location? or I can still use my old PERM and I-140 to file an adjustment of status. Kindly guide me. Thanks in advance!
