I emailed HEC for their advice on following dates so we can apply the VISA accordingly.

1) What is the last date of reporting to Middle East Technical University (METU)?
2) What is HEC's planned travel date to Turkey (when HEC is purchasing tickets) for candidates for Middle East Technical University (METU)? So we can ensure that our VISA starts before that.

Mr Jamshaid Responded;

"You my find the answers of your questions if you check with university. When the classes will start and when you will be there.

I will only guide you that you may start for your visa. Submit your visa to HEC then HEC will proceed you in last week of August, 2013."

Then I approached my Program advisor in METU and he referred me to ESRA TUZEN. She has not yet answered.

At the moment, I think we should stick to their academic calender 2013-2014
