Most people who want a second residence or passport begin by choosing a program. That order of work hides the routes they may already qualify for.
Citizenship by descent through a Polish grandparent costs little more than document fees, and it produces an EU passport. Around 10 million Polish Americans may have a claim.
Marriage to a Spanish citizen cuts the naturalization wait to one year. Most other nationalities wait ten.
The IMI Path Matcher checks routes like these before you price a program.
It compares thousands of paths to residency or citizenship against the profile you enter, and matches you with the ones that most closely fit your eligibility and preferences.

What each match tells you
Every result gives the country, the path type, a match percentage, the timeline, and the reasons the route fits what you entered.
Results also flag conditions that disqualify people who assume they qualify. Germany transmits citizenship by descent to grandchildren under the standard rule.
Great-grandchildren can claim only under Article 116(2) of the Basic Law. That article requires that the ancestor lost German citizenship through persecution between 1933 and 1945.
Below the matches, a section titled “Ruled out by your answers” lists the paths that did not make the list. Each entry names the answer that removed it.
A minimum contribution above your budget produces one such entry. So does a processing time longer than the window you gave.
You can place up to three paths side by side and download that comparison. Your top ten matches also export as a PDF.
Whether you are researching options for yourself or for your client, the Path Matcher is the natural place to start to surface all your options.
