I am imran shaikh Just i had completed my electrical engineering. So which courses i have to do. To work in gulf country and how much scope?

You can work as a trainee as per company's requirement otherwise there will some courses for the automation and also on MEP

Contracting ( autoCAD, Dialux)

My advice is for you to read more about practical electrical and hands-on applications in construction if you're prepared to come to gulf countries, otherwise you can also read more on practical and hands-on electrical applications in power and control if you're prepared to go into electrical maintenance and operations. Lastly, you can read more on electrical standards (local and international) and applications on installations if you're prepared to go into engineering & design in constructions.

If you are interested in maintenance operations , you must take some course on Siemens Micro-master AC inverters and Siemens PLCs as they are most common here.

Go into a power plant .. your life will be brilliant ..
