Well I've got a few good reasons:
1) I love the Middle East. I've been volunteering there for a few years, and even studied abroad in Abu Dhabi for a few months. It was amazing. I also know Arabic.
2) I want to specialize in global public health surgery / humanitarian medicine. I want to work in the developing world, as well as Europe, Asia, and the Middle East. I just want to travel and have a global reach in my medical career and I think learning medicine in such a global context would be greatly beneficial and unique.
3) Easier to get in? Probably
Lastly, 4) Amazing weather, cheaper accommodations and living expenses, and still get the NUI and RCSI degrees
All this coming from a graduate of NYU and currently working at an Ivy League Medical Center 🙂
