What are the residency requirements associated with Act 60?

Bona fide residency via the IRS is different than Act 60 residence as judged by PR, right?

As long as you aren’t in the mainland more than 90 days theres actually no days requirement for act 22. However, your biggest problem will be proving closer connection especially if you start staying in some countries for long periods of time and PR is not the country you stay the longest
