Thank you so much for the advice you gave me in private about using a postgraduate diploma for non-B instead of a degree, which I lacked. I followed your advice, went to the Vientiane Thai Embassy, and they requested my saqa and a transcript. They calculated everything, then took my passport. When I returned today, it had a stamp. Thank you for those who have advised me accordingly indeed a postgraduate diploma is above a degree
