How to immigrate to Egypt?

It's easy to sign many travel and business contracts in Egypt now, but I don't know much about immigration, but I can tell you one thing: First, Egyptian investors can get a maximum residence period of four years at a time, and I think short-term residence for landlords is enough; Second, if you immigrate, I think you have to get permission from Egypt first. For example, what skills you have is not as good as what skills they lack. You can't just spend money. Third, I heard that the Egyptian immigration law prohibits foreign men from becoming naturalized, and foreign women can only obtain Egyptian nationality if they marry Egyptian men; Fourth, reeducation through labor. Foreigners can only engage in the corresponding work after obtaining the entry permit issued by the competent department and living for work. I hope this helps.
