The 2012 poll was "How long are you planning on staying in Peru?" Here are the results.
less than a year: 22% with 29 votes
1-2 years: 21% with 28 votes
3-5 years: 20% with 20 votes
5-10 years: 6% with 8 votes
more than 10 years: 29% with 39 votes
It appears that people are here for the long haul. If that's the case, look into getting Peruvian citizenship. One tip to remember is that speaking Spanish will help you greatly.
You'll be treated differently than if you speak English all the time,
it'll help you assimilate to Peru, and it'll get you cheaper prices. If
you're looking to learn Spanish, the two programmes I recommend are Synergy Spanish and Speak From Day 1.
