VCU is the biggest/most well known but that's because its a large state school while other universities in Richmond are all private. University of Richmond (expensive) and Virginia Union (HBCU) are the other two schools that would likely have a MSW program in addition to VCU.

Virginia State is a public HBCU in Petersburg though I have no idea about any of their programs.

UVA could work depending on the course load but in that case, so could William and Mary in Williamsburg. But it would really depend on how the courses are done. If you can't do much of it remote then that would be tough assuming you're also working full time. It's tough to go to school locally while working full time.

Or:

Randolph - Macon in Ashland (about 20-30 minutes from downtown richmond) or Longwood in Farmville (hour-ish).

​

Other state universities have satellite campuses in Richmond as well but I think unless you have really specific requirements you'll have plenty to see just talking to the departments at VCU and other locals.
