Have you ever been to Peru before? Or did ever live abroad?
Before packing all your stuff and move here permanently, I suggest that you spend a few weeks here sampling life in Peru.
Is your income steady and your job secure? Peru is a nice country to live, as long as you have an income that can pay all your bills and you are in good health. There's no wellfare or state handouts here if things go bad for you.
It's not easy to get a CE (permanent residence permit). You must either invest $30000 and employ at least 4 Peruvians, get a pension from your home country, get employed by a company that's willing to sponsor your work visa or get married to a Peruvian which is the easiest way to get your permanent residence.
The easiest way is to live here on tourist visa. Immigration gives you up to 183 days at a time. After 183 days, you do a borderhop and come back. If you don't borderhop, then you have to pay a $1 fine for every day that you have overstayed. After you paid the fine, you can come back into the country next time around.
Be aware that prices in Peru aren't that cheap like they were used to be. Prices have increased a lot in the last few years. Even so that many products in Peru are far more expensive than in the US.
