Firstly, it was not general letter, except for ugc. I requested director of Amity distance learning, and they know about wes issue.
For ugc letter I went to ugc office near India gate, they were very nice people, they gave me a print out of letter issued to Amity to conduct the course for the year, when I took admission. So let me know what course and years of admission is yours, then I can suggest.
So ultimately, I want to share one thing, whatever course it is , whatever University it is,, just get the letter from ugc and send it to iqas along with application and explain about this on area given for explanation in the application form. If you have this ugc letter no one can stop you, IQAS clearly says on their website, that they follow UGC for any recognition.
This letter is also published in the admission brochure, at the time when we take admission.
Hope this will help everyone here suffering from Wes evaluation.
