Green card vs. citizenship: what's the difference?
A green card and citizenship both mean a permanent life in the United States — but they are different legal statuses with different rights, different obligations, and different durability. Here is the comparison, each claim cited to its source. General information, not advice about whether any particular person should naturalize.
What a green card is
Lawful permanent residence is the right to live and work in the United States permanently. The status itself doesn't expire, but the card evidencing it is renewed every 10 years, and the status carries maintenance obligations: it can be lost through extended residence abroad treated as abandonment, and certain conduct can place a permanent resident in removal proceedings. Permanent residents also cannot vote in federal elections, and their family-petition options are narrower — a permanent resident can petition a spouse and unmarried children, but not parents, married children, or siblings.
What citizenship adds
Citizenship replaces maintenance with permanence: no card renewals, no abandonment rules, and no exposure to the removal grounds that apply to permanent residents. Citizens vote in federal elections, carry a U.S. passport, and hold the widest family-petition categories — including parents, married sons and daughters, and siblings. One question this page deliberately doesn't answer: whether naturalizing affects your original citizenship. That is the law of your home country, and the honest answer lives with its consulate or a lawyer who practices its law.
The bridge: naturalization
The path from one status to the other is Form N-400, generally available after 5 years as a permanent resident — or 3 years for those married to and living with a U.S. citizen, with all other requirements. Under the current G-1055 schedule the N-400 costs $760 on paper or $710 online, with a reduced $380 fee for documented household income at or below 400% of the Federal Poverty Guidelines. USCIS fees change periodically — verify current amounts at uscis.gov/g-1055. The naturalization eligibility guide covers the requirements in depth, and the citizenship cost guide breaks down the full price of the move.

Choosing to stay a permanent resident
Plenty of people remain permanent residents for years or for life — the status is genuinely permanent when maintained. The comparison above is the honest trade: a maintained green card keeps the life you have; naturalization ends the maintenance and adds the citizen's rights. Anyone weighing the move with a complicated history — long trips abroad, tax questions, anything criminal — should put their facts in front of a licensed immigration attorney before filing anything.

Does a green card expire?
The status doesn't; the card does — it's renewed every 10 years. The status itself can be lost through abandonment (extended residence abroad) or removal on certain grounds, which is the durability difference from citizenship.
Can a green-card holder vote?
No — voting in federal elections is a citizen's right. Registering or voting as a non-citizen is a serious problem for any future case.
Who can a citizen petition that a green-card holder can't?
Parents, married sons and daughters, and siblings. A permanent resident's petitions are limited to a spouse and unmarried children.
When can a green-card holder apply for citizenship?
Generally after 5 years as a permanent resident — or 3 years when married to and living with a U.S. citizen — with all other N-400 requirements met.
Will becoming a U.S. citizen cost me my original citizenship?
That depends on your home country's law, not U.S. law — check with its consulate or a lawyer who practices that country's law.
