Being a foreign in Cairo can be good and bad, let me explain both:
Good
Being treated like a Princess everywhere you go;
Companies will hire you just because you are foreign;
Earning more money than most Egyptians for the same job;
Of course if you earn more you have access to places in Cairo that you will never think about it
Bad
Everything it’s much more expensive for a foreign (however most of them choose to live in places like Zamalek and Maadi where everything its overpriced);
You must have HIV exam made every time you go out;
A belly dancer will also have her passport confiscated;
