How to show the accreditation of a university abroad I live in the U.S but got my undergrad from a university in another country.
Now I have applied for Masters in the U.S and the department of graduate studies have requested this information from me, How do I provide it to them? What are they looking for?

Also: The university is Sheikh Bahaei University


  Is the university where you obtained your undergraduate degree an
  accredited institution?  That is, is it of a reasonable quality in
  some quantifiable ways?
Various countries have different accrediting bodies. Wikipedia has a nice overview.

From what you've written, it seems like they are looking for some information about what body (usually a private accrediting agency or a government ministry of education) your undergraduate institution is accredited by. To use a school near me as an example, I might say something like:


  Brooklyn College is accredited by the Middle States Commission on Higher Education, as stated here.  You can see Brooklyn College listed on the accrediting body's website, here.


In your case, you can point them to this page, which shows that the university is accredited by the Ministry of Science, Research and Technology of Iran (which is the government body that is responsible for accreditation of institutes of higher education in Iran).
