About

About JetlagMath

A reference desk for people who want to live in another country for months or years, not days.

Visa programs come and go. Countries stay. JetlagMath organizes its coverage around countries and the routes into them, so a page stays useful after a single program closes or changes its price.

What the site publishes

Country pages with every legal long stay route. Announcements when a rule, price, or program changes. City notes drawn from resident reporting, with sources credited. Field notes from real residents who approved the final text. Money pages on cards, banking, transfers, and insurance, written as general information. Tools that readers can bookmark and reuse.

What the site never does

The desk never invents a number, a rule, or a date. The site carries no invented testimonials and no invented reader or contributor counts. Site reporting speaks in a desk voice. First person writing appears only in field notes from real contributors.

The verification method sits on the editorial standards page. Sponsored and affiliate material follows the affiliate disclosure.
