A "green card daddy" is an American man who becomes the romantic partner of a foreign woman, with the implicit or explicit assumption that the relationship helps her obtain U.S. residency. The term is a play on "green card" (otherwise known as a "permanent resident card"), which is a document that grants a person the right to live and work permanently in the United States.
Green card daddies are typically older, single, or financially stable (but do not have to be wealthy) men who are either genuinely seeking love or are willing to overlook the possibility that immigration benefits may be a motivator. People commonly use it online in dating discussions (often on social media) and reality TV commentary.
The term gained popularity in the late 2010s and early 2020s, especially in Internet forums, memes, and commentary surrounding shows like 90 Day Fiancé. While you will likely see or hear people use it sarcastically or playfully, the phrase can also carry a critical undertone, highlighting perceived imbalances in age, culture, or intention between partners. For example, younger people, particularly women, often use it to poke fun at or critique relationships where immigration benefits seem to play a suspiciously significant role.
