If you are a researcher in Pakistan, who has published a research paper in a conference abroad, you may avail the HEC Travel Grant for Conference Paper Presentation Abroad. However, be wary of the following:
1- Have a proof of oral presentation during the conference attached with the application for travel grant. This means a letter from the organizers.
2- When filling the application form, do not pay any attention to the airfare being the lowest with the "most direct route." Get PIA fare only. They dont say it in the application form, but the post approval sanction letter says that you must travel by PIA and if you dont, you must document the reason for not doing so. That requires approval from the Finance Ministry. If getting the grant approved isnt difficult enough, getting through another level of bureaucracy will be nearly impossible.
Happy presenting
