回复：请问现在该办绿卡吗？

I am not familiar with immigration issue, but in my opinion, as long as you can find riteaid in another state, i think you can start your GC since you are working with the same company only different location.

By the way, I will be joining riteaid in MI,would you mind leaving me your contact information, and I can get some suggestion from you? I appreciate your help very much.
