If you’ve ever held one, you know it isn’t exactly a vibrant, neon lime. It’s more of a pale, minty teal with a holographic sheen that dances under the light. Yet, the name stuck. People across the globe refer to the United States Permanent Resident Card by its iconic nickname, but have you ever stopped to wonder why are green cards called green cards when, for a solid few decades, they were actually pink, blue, or even a weird shade of yellow?
It’s a linguistic quirk that has survived bureaucratic overhauls, security upgrades, and several decades of color-palette indecision at the federal level.
Honestly, the name is a bit of a historical accident. It’s like calling a modern smartphone a "dial" phone just because that’s how it started. In the world of U.S. immigration, branding matters, but the physical reality of the document has often struggled to keep up with its own reputation.
The Alien Registration Act of 1940: Where it All Began
Before the 1940s, the U.S. didn't really have a standardized card for permanent residents. You had entry documents, but nothing you carried around in your wallet like a badge of honor. That changed with the Alien Registration Act of 1940. World War II was brewing, and the government wanted to know exactly who was in the country.
The first "cards" weren't even cards. They were paper receipts.
If you were a non-citizen living in the States, you had to go to the post office, get fingerprinted, and register. In return, you got Form AR-3. This was a white piece of paper. Not green. Not even close. But as the war ended and the Cold War began to simmer, the government realized they needed something more durable—and harder to forge—for those with legal permanent status.
In 1946, the Immigration and Naturalization Service (INS) introduced Form I-151. This is the moment the legend was born. The card was printed on heavy, distinctively green stock. It was simple. It was functional. Most importantly, it was green.
Because this card granted the right to live and work in the U.S. indefinitely, it became the most coveted piece of plastic in the world. People didn't want to say, "I have my Form I-151." That sounds like a tax audit. They said, "I got my green card." The nickname was born out of convenience, and it took such a deep root in the American lexicon that the government eventually gave up trying to call it anything else.

The Decades of Color Confusion
You might think that once the name caught on, the government would stick to the script. Nope.
By the early 1950s, the INS started worrying about counterfeiters. To combat the fakes, they started changing the design. Between 1952 and 1977, the card went through a bit of an identity crisis. At one point, it was a pale blue. Later, it shifted to a buff color.
Then came 1977.
If you applied for residency in the late 70s or throughout the 80s, your "green card" was actually pink. It was officially the Form I-551, but the color was a soft, salmon-y rose. Imagine telling your family back home that you finally got the "pink card." It just didn't have the same ring to it. So, despite the visual evidence to the contrary, everyone—lawyers, immigrants, and even the INS officers themselves—kept using the term "green card."
Language is stubborn.
In 1989, the card changed again. This time it was a sort of off-white with a pinkish pattern and a grainy texture. Still not green. Then, in 1997, it turned a light yellowish-green, but it was so pale it mostly just looked like dirty ivory. Throughout all of this, the "Permanent Resident Card" (the official name since the 90s) remained the "green card" in the hearts and minds of the public.
Why the Color Green Finally Came Back
After nearly 35 years of non-green green cards, the U.S. Citizenship and Immigration Services (USCIS) decided to lean into the brand. In May 2010, they announced a massive redesign. The goal was to make the card nearly impossible to replicate, using optical ink, laser-engraved fingerprints, and high-resolution imagery.

But the biggest change was the color. They made it green again.
It wasn't just a nod to tradition. By returning to the original color scheme, the USCIS simplified their own public messaging. They realized that the term had become a global brand. When a person in a small village in Southeast Asia or a tech worker in Berlin dreams of moving to America, they dream of the green card.
The 2010 version was a vibrant, grassy green. In 2017, they updated it again, moving to a more sophisticated "forest" palette with a picture of the Statue of Liberty and a more integrated green-to-gold shift. The current 2023 redesign has maintained this green-centric theme while adding even more layers of holographic security.
Beyond the Pigment: What the Card Actually Represents
It’s easy to get bogged down in the history of ink, but the reason why are green cards called green cards is ultimately about what they represent: stability.
A permanent resident card isn't just a permit to work. It’s a bridge. It sits in that crucial middle ground between being a "visitor" and being a "citizen." It allows you to travel, to start a business, and to eventually apply for naturalization.
There are two main types of these "green" documents that often confuse people:
- The Conditional Green Card: This is valid for only two years. It’s usually issued to people who get their residency through marriage to a U.S. citizen when the marriage is less than two years old. You have to "remove conditions" to get the permanent version.
- The Standard 10-Year Green Card: This is the one most people think of. It doesn't mean your residency expires in ten years, but the physical card does. You have to renew the plastic, much like a driver's license.
The Psychology of the Green Brand
Why didn't "pink card" or "blue card" ever take off? There’s a psychological component here. Green is the color of "go." In traffic signals, it means move forward. In finance, it’s the color of money—specifically the U.S. dollar, another "green" icon.

For an immigrant, green signifies a green light to start a new life. It represents growth and prosperity.
Even today, when you look at the official USCIS website, they don't hide from the nickname. While the headers might say "Permanent Resident," the FAQs often use the term "green card" in parentheses. They know that’s what people are typing into Google. They know that’s the term that carries the weight of the American Dream.
Practical Steps for Keeping Your Card Current
If you’re currently a holder of one of these iconic slips of plastic, or you’re about to be, there are a few things you need to do to make sure yours stays valid. Don't let the name fool you into thinking it lasts forever without any effort.
First, check your expiration date. Most modern cards are valid for 10 years. You should start the renewal process (Form I-90) about six months before it expires. If you have a 2-year conditional card, you must file to remove conditions within the 90-day window before it expires—missing this window is a fast track to deportation proceedings.
Second, keep your address updated. This is a big one that people miss. Federal law requires most non-citizens to report a change of address within 10 days of moving. You do this via Form AR-11, which is now mostly handled online.
Finally, understand the "abandonment" rules. A green card is for living in the U.S. If you leave the country for more than a year without a re-entry permit, the government might decide you’ve abandoned your residency. Even six months can raise eyebrows at the border. If you plan to be away for a long time, apply for a re-entry permit while you are still physically in the United States.
The history of the green card is a messy, colorful, and surprisingly bureaucratic journey. It started as a wartime security measure, turned into a global symbol, survived decades of being the wrong color, and finally returned to its roots. Whether it’s pink, white, or green, it remains the most significant piece of identification an immigrant will ever carry.
