More than 9 million Americans have Greek ancestry, with a large concentration of them in the Chicago area.
Your ancestor could have also lost their Greek citizenship if they became a citizen of another country before 1951.
If your ancestors are still alive, they can apply for restoration of citizenship in order for you to apply.

Greek citizenship is set by the Greek Nationality (or Citizenship) Code (Law No. 1438/1984) and other laws, especially Law No. 3284/2004. If a person's parent is a Greek citizen, they can acquire Greek citizenship at birth, even if the parent has not exercised their right to citizenship. A person must be registered in the records of a municipality in Greece to be considered a Greek citizen. Greek citizens who live in the United States can apply for a certificate of registration through the Greek consular office in their area. The Greek consular office will then send the application to the right Greek government office. To prove that you are Greek, you need a certificate of registration. You can get this by registering the marriage and birth of the applicant's parents at a Greek consulate in the United States.
The Greek Ministry of Interior, Public Administration, and Decentralization, not consulates, is in charge of deciding who is a citizen. People can use their right to become Greek citizens by going to the Greek consulate closest to them and showing proof of their Greek ancestry. It should be noted that Greek citizenship is an inalienable right for those born to a Greek citizen, and that consulates do not "grant" citizenship but rather assist individuals in exercising their right to citizenship in accordance with Greek law.
You can apply in Greece (you'll need a translator) or at a Greek embassy or consulate (you will need two witnesses who are Greek citizens). Needless to say, if you do it in the country, it will take much less time to process.
To submit your application, you'll need to gather the following documents:
All paperwork must be apostilled, translated into Greek, and certified. Some of the documents from Greece can be obtained through your local consulate. If you get your passport from your grandparents, be prepared to answer questions about their parents (your great-grandparents), such as their name, date of birth, and marriage.
