Refile PERM & I-140 if employer changes location?

[latin]

I have some questions regarding the Green Card process. I have a priority date of 05/23/2012 and also an approved I-140 in EB2 category. 

 

Do I need to start the GC process all over again and refile PERM and I-140 in any of the following circumstances?

1) If my employer changes location from one city to another city/state 

2) If the company’s name changes

If your job moves to a different metropolitan statistical area, the prevailing wage may be different, so that would require a new PERM.

For company name changes, USCIS just has to be informed.
