If your CE is still valid, you can open a business banking account (if you don't already have one). I would hire a good immigration attorney. If you can demonstrate some valuable skillset and/ or advanced degrees, better still. You can set up a Sociedad Anonima Cerrada (S.A.C.) with yourself as the only employee, the legal representative, and general manager. There is a perfectly legal loophole in this business entity where you do not have to hire 4 or 5 Peruvians. Pay yourself a minimum monthly salary which equals 10 U.I.T. annually for 2 or 3 years (this period may have changed with the new TUPA). Unfortunately you will have to pay ESSALUD and AFP pension on your salary each month. At the end of this 2 or 3 year period (when you are free to suspend or close your business), you convert your annual CE into a permanent resident CE, status Inmigrante, which lasts 5 years and is much more easily renewed at the end of those 5 years. This is what my lawyer did for me and, unlike a retirement visa, it allows you to work.
