I hold a degree from a European country, and at that time we didn't have a system similar to the common "Bachelor + Master". My degree has been considered as equivalent to a Master by the University of another European country, and in this other University I obtained a Doctorate.
Now, I have been offered a teaching position in Russia, and they want a statement of my undergraduate University, saying that that degree is equivalent to a Master. But this University (where I graduated) tells me that they can't make a statement of equivalence, they can only certify that I have that degree. So, who should be the authority that officially takes care of confirming the equivalence?
To complicate things, I graduated before the Bologna Process came into effect.
