What is Israel’s Law of Return? It is the 1950 Israeli law giving Jews the right to immigrate to Israel and become citizens. A 1970 amendment extended that right to the children and grandchildren of a Jewish person, and to their spouses — which means someone with a single Jewish grandparent can qualify even if they are not Jewish under religious law.
Important: Masa eligibility and Law of Return eligibility are not the same thing
Being accepted onto a Masa program does not mean you are eligible for Aliyah, and being eligible under the Law of Return does not automatically mean you are accepted onto a Masa program. They are separate assessments made by different bodies against different criteria.
This page explains the law in general terms. It is not legal advice, and only the Jewish Agency, Nativ, or an Israeli consulate can tell you whether you personally qualify.
What Israel’s Law of Return is
The Law of Return (Chok HaShvut) was passed unanimously by the Knesset in July 1950, two years after the founding of the state. Its first clause is one sentence long and does most of the work: every Jew has the right to come to Israel as an oleh, an immigrant.
That sentence reverses the ordinary logic of immigration. In most countries a person applies to be admitted and the state decides. Under Israel’s Law of Return, the right exists first and the state’s role is to confirm that the person holds it. Someone who immigrates under the law receives citizenship on arrival rather than after a period of residency.
The law was written against a specific backdrop — the aftermath of the Holocaust and the displacement of Jewish communities across Europe and the Middle East — and the intention was explicit: that there would never again be a Jew with nowhere to go.
Who is eligible under Israel’s Law of Return
Israel’s Law of Return as passed in 1950 applied to Jews. In 1970 the Knesset passed Amendment No. 2, adding section 4A, which extended the same rights to a defined circle of relatives. The practical effect is that eligibility runs three generations deep and includes spouses.
The line at the fourth generation is firm, and it is the most common place people discover they do not qualify. If your only Jewish ancestor is a great-grandparent, the Law of Return does not apply to you, however strongly you identify.
The grandchild clause, and why it exists
The grandchild clause is the most consequential part of the law and the most frequently misunderstood. It means a person with one Jewish grandparent can immigrate and receive citizenship even if they are not considered Jewish under halacha, Jewish religious law.
The reasoning behind the 1970 amendment is usually traced to the Nuremberg Laws. Nazi Germany defined a Jew for the purposes of persecution as anyone with a Jewish grandparent. The amendment drew Israel’s circle of protection at the same radius: if having one Jewish grandparent was enough to be persecuted, it should be enough to be given refuge.
That produces a genuine gap. Someone can arrive under Israel’s Law of Return, receive citizenship, serve in the army and raise a family in Israel while still not being recognised as Jewish by the Chief Rabbinate — which controls marriage and burial for Jews in Israel. The law confers citizenship, not religious status, and the two have never been the same thing.
Is the grandchild clause being removed?
It has been the subject of repeated legislative attempts, and as of this writing none has succeeded. Bills to remove it have been proposed periodically since the 1990s. A bill that would have eliminated the clause was voted down in the Knesset in 2023, and subsequent proposals have not been enacted. The grandchild clause remains in force.
Because this is an active political question, anyone making plans that depend on it should confirm the current position with the Jewish Agency or an Israeli consulate rather than relying on an article.
Who is not eligible
Three groups fall outside the law even where the family connection exists.
Great-grandchildren and more distant descendants. As above, the law stops at the third generation.
A Jew who has voluntarily converted to another religion. This is the exception written into the 1970 amendment, and it is a point of real complexity: a person born Jewish who adopts another faith can lose their right under Israel’s Law of Return, even though they remain Jewish under halacha. The provision is about choice — it does not apply to ancestors who were forcibly converted, and a grandchild is generally assessed on their own religious practice rather than their grandparent’s.
Applicants excluded on public-interest or security grounds. The law allows the Minister of the Interior to refuse someone judged a danger to public health, state security, or with a significant criminal history.
Not sure where you stand?
A short call with the Masa team can help you work out which programs you can apply to and what documentation you will need.
Schedule a callHow Israel’s Law of Return relates to Masa eligibility
Masa programs are built for young Jewish adults from around the world, and Israel’s Law of Return is the reference point most Jewish organisations use when defining who that includes. But the relationship is narrower and more specific than most people assume, and it is worth being precise about it.
Masa sets its own criteria — age range, program type, and the documentation described below — alongside the Jewish background requirement. The full criteria, and the application itself, are on the Masa eligibility and application page.
Masa’s own guidance states this directly: being deemed eligible to participate in a Masa program does not grant eligibility for Aliyah. The two decisions are made separately. A Masa eligibility check confirms that you can join a program. It does not create, confirm or imply a right to immigrate.
When a Law of Return check is actually required
For most applicants it is not. Whether you need a formal eligibility check depends on where you are applying from, and the requirement exists for visa and consular reasons rather than as a test of Jewishness.
| Where you’re applying from | Eligibility check required? |
|---|---|
| USA, Canada, UK, Western Europe, South Africa, Zimbabwe | No additional documents. Complete the Masa application as prompted. |
| Most of Latin America, including Brazil | No additional documents. Complete the Masa application as prompted. |
| Former Soviet Union | Yes — consular approval, Nativ certification, or an Israeli passport. |
| Eastern Europe, including Hungary | Yes — a check through the Jewish Agency. |
| Colombia, Ecuador, El Salvador, Honduras, Peru, Cuba, Venezuela, Puerto Rico, Dominican Republic | Yes — a check through the Jewish Agency. |
| Maghreb countries, Africa excluding South Africa and Zimbabwe, Ethiopia, India | Yes — a check through the Jewish Agency. |
| China | Yes — a check through the Jewish Agency. |
Two points matter here. The check is carried out by the Jewish Agency or by Nativ, not by Masa, and Masa cannot influence the outcome. And passing it establishes that you can join a Masa program — not that you qualify for Aliyah.
One category works differently. Fellows on tracks requiring a B1 work visa, such as Masa Tech and Fast Track Pro, need a Law of Return eligibility check regardless of which country they are applying from, because of how that visa is issued.
Full details, including document lists and the forms for each region, are on the Masa visa page.
What documents prove eligibility
Where a check is required, the Jewish Agency is generally looking for documentary evidence of the Jewish ancestor and of the chain of relationship connecting you to them. In practice that usually means some combination of the following.
Records of the Jewish relative — a birth, marriage or death certificate, a ketubah, a burial record, synagogue or community records, old identity papers listing nationality or religion, or immigration documents. Then the connecting documents: birth and marriage certificates for each generation between that ancestor and you, so the line can be traced without gaps.
Older families often find this harder than expected, particularly where records were lost in the Holocaust or in Soviet-era archives. Communal and genealogical archives can sometimes fill a gap, and it is worth starting early — gathering documents across several countries is usually the slowest part of any application.
Israel’s Law of Return and Aliyah are not the same process
Eligibility is a status. Aliyah is a process you undertake — an application, usually through the Jewish Agency or an Israeli consulate, with its own documentation, interviews and timeline, ending in immigration and citizenship.
A person can be eligible under Israel’s Law of Return for their whole life and never make Aliyah. Many do exactly that. Equally, spending time in Israel on a Masa program, a student visa, or any other temporary status does not begin an Aliyah process or confer any immigration right. The visa a Masa fellow holds is a temporary one tied to the program.
Israel’s Law of Return: common questions
What is Israel’s Law of Return?
It is the Israeli law, passed in 1950, granting Jews the right to immigrate to Israel and receive citizenship. A 1970 amendment extended that right to the children and grandchildren of a Jewish person and to their spouses.
Who is eligible under Israel’s Law of Return?
A Jewish person, the child of a Jew, the grandchild of a Jew, and the spouses of all three. Eligibility stops at the third generation, so great-grandchildren have no independent right under the law.
Do I qualify if only one grandparent was Jewish?
Generally yes. This is the grandchild clause, added in 1970, and one Jewish grandparent is enough — even if you are not Jewish under religious law. Only the Jewish Agency or an Israeli consulate can confirm an individual case.
What if my great-grandparent was Jewish?
Israel’s Law of Return does not extend to great-grandchildren. If your only Jewish ancestor is a great-grandparent, you are not eligible under the law on that basis.
Does being eligible under Israel’s Law of Return make me Jewish?
Not in religious terms. The law grants immigration rights and citizenship, not religious status. Israel’s Chief Rabbinate applies its own criteria for matters such as marriage and burial, and many people eligible under the law are not recognised as Jewish by it.
Has the grandchild clause been repealed?
No. Bills to remove it have been proposed repeatedly, and one was voted down in the Knesset in 2023, but none has passed. The clause remains in force. Because it is an active political question, confirm the current position before making plans that depend on it.
Does Masa eligibility mean I am eligible for Aliyah?
No. Masa states this explicitly: being deemed eligible to participate in a Masa program does not grant eligibility for Aliyah. The assessments are separate and are made by different bodies.
Do I need a Law of Return check to join a Masa program?
It depends on where you apply from. Applicants from the USA, Canada, the UK, Western Europe, South Africa, Zimbabwe and most of Latin America do not need additional eligibility documents. Applicants from the FSU, Eastern Europe, parts of Latin America, much of Africa, India and China do. Fellows on B1 work visa tracks need a check regardless of country.
Who decides whether I am eligible?
The Jewish Agency, or Nativ for applicants from the former Soviet Union. Masa does not carry out the check and cannot influence its outcome.
Does a Masa program lead to citizenship?
No. A Masa fellow holds a temporary visa tied to the program. It does not begin an Aliyah process or confer any immigration right.
Eligible, curious, or somewhere in between?
Masa runs programs in Israel for people aged 16 to 40 — study, work, volunteer, career. A few weeks or a full year, with no commitment beyond the program itself.
