A bureaucratic hell, anything that you will try to do will he deemed illegal for foreigners, and you will end up paying hefty fees for a lawyer or under the table loads of money.
No CRS, but you can only transfer foreign currencies out of the country and you can't buy foreign currencies ( black market and crypto bans strictly enforced), so your local income wil
be trapped ( as in Algeria) with a 5 to 8% interest at the bank and a 35% inflation, waiting for the next devaluation.
Even making a foreign transfer can take months in some banks as they will pretend waiting for the central bank green light, asking for a proof of why you want this money out ( overseas real estate purchase contract on your name for example). You will need to travel. Can be avoided by using HSBC or french bank Credit Agricole, among other foreign banks.
If you re still interested for some reason, my english/french lawyer can help with an affordable and fair service, which is a rare find. But you ve been warned!
Most foreign investors pack back after some time. Mostly overseas based Egyptians know how to swim, and their connections and double nationality is a big advantage for overriding the endless regulations. They primarily come for family purpose anyway.
The idea is to generate no income in Egypt, so none of those problems would exist in what I proposed originally: living in Egypt off foreign income.
One would just bring money into Egypt, from abroad, to pay for living expenses. There would be no need to take money out or to set up a business.
