It is the authentic news that only 2 from Pakistan, 5 from India and 15 from Canada and so on... have been selected for Mexican govt. Scholarships. and from Pakistan one student is selected for Post. doc and the other for Ph.D, and both of these have been informed but Mexican authorities. and the Visa problem is really complicated because Mexican embassy is not working in Pakistan since many years, there fore the successful nominees will go to UAE OR Tehran for Visa interview.
From which university you and your friend got the scholarship? i will also going to appear in an interview of IPN university scholarship, Lapaz city this month.
Best of Luck.
