Is there any difference between 12 month M.E. Visas with коммерческая written on them and those with деловая written on them. I was told just before successfully receiving Temp. Res. to leave the country and change my коммерческая to a деловая or Homestay Visa.

Surely if there was a problem they would/should have told me at the beginning of the process. That's probably expecting too much from these people.

Now I have to go and talk to somone higher, so any information appreciated.
