It depends on your passport, investment and where in Egypt you want to relocate.
Easiest: Invest in Egyptian real estate. By far the best place for that is The New Administrative Capital. The developer will help to solve the ubiquitous bureaucracy. Minimum USD 100k investment will give you a one-year visa, for USD 200k you get a visa for a period of three years, for USD 400k this can extend to a five year period.
All of the aforementioned visas are renewable for the same︀ period as long as you are still the owner of the orginal property.
