Hi
Yes unfortunately the EK group cannot hire any Iranian nationals at present because of political differences between the 2 countries.
I personally know a manager who was offered a job at EK but they would not transfer his visa even tho he lives in Dubai.It went to the highest level but to no avail.
We do have plenty of Iranians in the company but that is the situation currently.
Sorry.
Perhaps it will change in a few years.
Good luck
