Canada
The most predictable points system, and the one that leads to a passport fastest.
Express Entry is the closest thing this market has to a transparent queue. You submit an expression of interest, receive a Comprehensive Ranking System score built from age, education, language test results, work experience and a handful of adaptability factors, and then wait for a draw. If your score clears the cut-off, you are invited to apply for permanent residence directly — not for a temporary permit that might become permanent.
Two things follow from that design. The first is that your score is knowable in advance: you can calculate it before spending a cent, and you can see historical draw cut-offs, so the question “am I competitive” has an answer rather than a guess. The second is that language testing is the highest-leverage thing most candidates can change. Age and education are fixed by the time most people are reading this; a better IELTS or CELPIP band is not, and it moves more points than almost anything else available.
Canada also has the shortest route to citizenship of any system here — three years of physical presence as a permanent resident, against four in Australia and five in most of Europe. For anyone whose actual objective is a second passport rather than a place to live, that gap is the single most consequential number on this page, and it is the reason a skilled route is often a better answer than an investment route for candidates who score well.
The pressure point is volume. Category-based draws now favour specific occupations, French-language ability and in-Canada experience, which means a strong general score is worth less than it was three years ago. Check which categories are being drawn before assuming a high CRS is sufficient on its own.
