Hi,living in Egypt is very safe do not worry about that .I live in Cairo that is why Isay it is safe to live there .Learing Arabic is not easy special the stylistic language ,but easier to learn the LOCAL ARABIC like most of my freinds in Cairo.
Living with your partener is not forbiden but you have to choose the right place to live in .
Bringing your dog is acceptable but you have to take care about its paper .Most pepole in Egypt have dogs .there is vet.There is also place to keep your dog in when you go to a far place and you need to leave the dog to someone to take care .
Drinking wine should be in special hotels and bars .Not allawed in the public streets.
Clubs are available and can be found every where .
International food is available but in 5 stars hotels ,special places down towen and malls.Feel free to contact me and good luck .
