I haven’t yet. Actually, the corrupt bureaucracy has withheld residency status so far without bribes. That said, here was the path I thought I was on when I moved.

The idea is to have been in the country for most of the year (no less than 14 days out of country), at which time you can apply for residency. Once you have residency, you must maintain it for 5yrs.

Citizenship for Permanent Residence Holders

1. You have been a holder of Permanent Residence for a minimum of 5 years.
2. You have been resident continuously in Belize, this means that upon being granted Permanent Residency you have not resided outside Belize for periods that exceed thirty consecutive days or accumulate to a total of three months in any twelve month period.

I didn’t want to muddy the waters with the reality of what happened once I moved, as the OP was about motivating factors. Power corrupts. And ultranationalism is infectious to other countries.
