How to get citizenship of another country: five legal paths

There are only a handful of lawful ways to acquire the citizenship of another country, and all of them are written into statute. There is no shortcut around them — only document fraud, which ends in annulment and a criminal case. Below are five legal paths, ranked from most to least accessible.

1. Descent

The fastest route, if you have it. Citizenship passes by blood — from parents, sometimes from grandparents, and in a few countries further back still. You need to document an unbroken chain of descent: archival birth, marriage and residence records.

Where it breaks down: documents are lost, names are spelled differently across records, or the degree of kinship falls outside what the law allows. Rebuilding an archival trail is slow, separate work — but it is lawful, and it delivers results.

2. Naturalization by residence

The universal route: live in the country for a set period under legal status, pass a language test, sometimes a civics exam, and show income and a clean criminal record.

The details that matter: the clock runs from permanent residence, not from your first entry; long absences interrupt it; and some statuses don't count toward it at all. There is no way to speed the process up — that is the one point every jurisdiction agrees on.

3. Marriage

Shortens the naturalization period but doesn't eliminate it. You typically need to be married for several years, often living together and in the country. Marriages are checked: shared housing, shared life, witnesses, sometimes separate interviews. A sham marriage is a criminal offense in most countries, and it is caught regularly.

4. Investment

Available in a limited number of countries, in two forms: direct citizenship by investment, and residency by investment followed by naturalization. Few of the direct programs remain, and they are under constant outside pressure; the residency route is more widespread.

What matters here: source-of-funds checks are strict, applications can be refused, fees are not refunded if they are, and program terms can change while your application is under review.

5. Special provisions

Granted for merit — science, sport, culture. The initiative comes from the state, not the applicant; there is no application procedure, and only a handful of decisions are made each year. This path cannot be bought, and any offer to sell it is either an advance-fee collection or a scheme that gets unwound later.

Where to start

1. Check descent first — it costs nothing and can close the question entirely.
2. Work out which basis is actually available to you, and check its requirements against the country's law, not a sales presentation.
3. Count the timeline honestly: from getting status to applying for citizenship, including the presence requirement.
4. Find out whether you'll have to give up your current citizenship.
5. Check whether you're obliged to notify your current country of your new status.

Bottom line

All five paths are long, and that's normal: a short path to citizenship is a sign that what's being sold isn't citizenship. This material is for informational purposes only.
