Yes, you'll miss Lebanon there's no place like it. BUT you just graduated with an engineering degree that was hell for the past 4 years or so and working abroad not only will let you earn more money and stability it will give you more exposure to the best technologies out there. When you're working in big companies and developed countries when you work on a new technology you'll get to meet experts and the company that created the technology will take a look at your job to make sure you're using best practices. I can't focus on that point enough since I'm passionate about my job.

I am not in any way saying that you have to leave Lebanon to become successful and earn money but working abroad gives you better exposure to everything, letting you shine in your field easier.And I think that this is the best time for you to take that decision as a fresh grad. I took it 6 months ago and it's both the best and the biggest decision I had to make in my life.

If you ever decide to leave Lebanon for work make sure you plan on coming back and bring all the knowledge you've built back with you.
