Green Card vs. Visa: What's the Difference?

Green card vs. visa: a visa is temporary permission to travel to a U.S. port of entry and ask to be admitted for one purpose, like a visit, school or work, and a green card is permanent residence. Visa holders live by an end date and a list of allowed activities; green card holders can work anywhere and stay indefinitely.

Visa vs. green card: what each one lets you do

Visitors, students and temporary workers are nonimmigrants, each in one of the lettered classes of 8 U.S.C. 1101(a)(15). A green card holder is a lawful permanent resident under 1101(a)(20). These are federal rules, so they don't change from state to state.

	On a temporary visa	With a green card
How long you can stay	Until the "admit until" date on your Form I-94. Students and exchange visitors are usually admitted for "D/S" (duration of status), which lasts as long as they keep up their program.	Indefinitely. A 10-year card expires and gets renewed, but your status and permission to work don't expire with it (8 CFR 274a.12(a)(1)). A 2-year conditional card is different: status ends on its second anniversary unless you file Form I-751 in the 90 days before (8 U.S.C. 1186a(c)(2), (d)(2)).
Work	Only what your class allows. B-2 tourists can't work at all, and a B-1 covers business visits, not a U.S. job (8 CFR 214.1(e)).	Any job with any employer, or your own business.
Travel	Each return is a new request for admission, usually on an unexpired visa stamp, and the officer at the port decides (8 U.S.C. 1201(h)).	The card works for reentry after trips of under a year (8 CFR 211.1(a)(2)). After more than 180 days away, you're treated as seeking admission (8 U.S.C. 1101(a)(13)(C)(ii)).
Family	A spouse and minor children can usually join you in a dependent class (H-4, L-2, F-2, TD), but you can't sponsor relatives for green cards.	You can petition for a spouse and unmarried children in the F2A and F2B categories (8 U.S.C. 1153(a)(2)).
Path to citizenship	None; time on a temporary visa doesn't count toward naturalization.	Apply after 5 years as a resident, or 3 if you've been married to and living with a U.S. citizen (8 U.S.C. 1427(a) and 1430(a)).

D/S is in flux. A DHS rule replacing it with fixed periods of up to four years was due September 15, 2026, but a federal court in Massachusetts postponed it the day before, and USCIS is following the earlier rules while the case continues. Check with your school's international office.

## Nine common visas and whether they can lead to a green card

Under 8 U.S.C. 1184(b), every visa applicant is presumed to be an intending immigrant until they prove otherwise. H-1B and L-1 workers are exempt from that presumption, and their regulations let them come temporarily while seeking permanent residence, which is what dual intent means. Most other classes require a home abroad you plan to keep, so starting a green card case can undercut the visa.

Visa (1101(a)(15) letter)	What it's for	Can you work?	Can it lead to a green card?
B-1/B-2 (B)	Business trips (B-1), tourism or medical visits (B-2)	No U.S. employment	No dual intent; you must keep a foreign home you don't plan to abandon.
F-1 (F)(i)	Full-time study at an approved school	Limited: up to 20 hours a week on campus during the term, plus practical training in your field (8 CFR 214.2(f)(9), (10))	No dual intent; a foreign residence is required.
J-1 (J)	Exchange programs for students, scholars, researchers, teachers and trainees	Only the program's activity, such as teaching, research or training	No dual intent, but a green card (say, through marriage) is possible unless you're subject to the 2-year home residence rule and haven't met it or gotten a waiver (8 U.S.C. 1182(e); 8 CFR 245.1(c)(2)).
H-1B (H)(i)(b)	A specialty occupation job that requires at least a bachelor's degree in the specific field, or the equivalent	For the sponsoring employer, up to 6 years (8 U.S.C. 1184(g)(4)), with extensions for some green card applicants (AC21 secs. 104(c) and 106)	Yes, dual intent (8 CFR 214.2(h)(16)).
L-1 (L)	Managers, executives and specialized-knowledge staff moving from an employer's office abroad after a year there in the last 3	For that employer or an affiliate, up to 7 years (5 for specialized knowledge)	Yes, dual intent (8 CFR 214.2(l)(16)).
O-1 (O)(i)	Extraordinary ability in science, arts, education, business or athletics, with sustained acclaim	In your field, for the petitioner	Not on the statute's dual intent list, but a green card petition can't be the reason USCIS denies an O-1 (8 CFR 214.2(o)(13)).
TN (no letter; USMCA)	Canadian and Mexican professionals in listed occupations	For the U.S. employer named in your TN; a new employer needs a new filing (8 CFR 214.6(i))	No dual intent: entry must be temporary, with "a reasonable, finite end" (8 CFR 214.6(b)), so a pending green card case can block TN entries or extensions. A green card, for example through marriage, is still possible.
K-1 (K)(i)	Fiancé(e) of a U.S. citizen, coming to marry the petitioner within 90 days of admission	Yes, with a work permit (EAD), during the 90 days (8 CFR 274a.12(a)(6))	Yes, through that marriage only, as a conditional resident (8 U.S.C. 1255(d)).
E-2 (E)(ii)	Treaty-country nationals who invest substantially in a U.S. business they develop and direct	In that business only; an E spouse is authorized to work (8 U.S.C. 1184(e)(2))	You must intend to leave when E status ends, but a green card petition alone isn't grounds for denial (8 CFR 214.2(e)(5)).

TN has no letter in 1101(a)(15); it comes from the USMCA and 8 U.S.C. 1184(e), which keeps the presumption of immigrant intent. Canadians get TN status from the border officer with no visa, while Mexican citizens need a TN visa first (8 CFR 214.6(d)).

Finishing a green card case without leaving

Adjusting status inside the U.S. (8 U.S.C. 1255(a)) is discretionary and requires that you were inspected and admitted or paroled. A USCIS memo dated May 21, 2026 (PM-602-0199) tells officers to treat it as extraordinary relief when consular processing abroad is available and to treat a failure to depart as expected as highly relevant, while noting that filing is consistent with a dual intent status. People who worked without authorization or fell out of status are generally barred (8 U.S.C. 1255(c)) unless they're immediate relatives of U.S. citizens (8 CFR 245.1(b)), and under the memo, an overstay or unauthorized work still counts against an immediate relative as a discretionary factor.

Your visa stamp vs. your I-94

The visa in your passport and your permission to stay often end on different dates. A visa's validity is just the window for using it to ask for admission, and it has no relation to how long you may stay (22 CFR 41.112(a)). The CBP officer sets your stay at admission and records it on Form I-94, which you can download from CBP's I-94 website or the CBP Link app.

When the stamp expires first

Say CBP admitted you in H-1B status with an I-94 good through September 30, 2029, but the visa stamp in your passport expires March 31, 2027. (Visa validity follows reciprocity schedules for your country, not your petition.) From April 1, 2027 through September 30, 2029, a stretch of 914 days, you can stay and keep working. You just can't leave and return on that stamp without first getting a new visa abroad.

One exception, automatic revalidation, can let you return on the expired visa after a trip of 30 days or less to Canada or Mexico if your I-94 is unexpired, you've kept your status and you didn't apply for a new visa while away (22 CFR 41.112(d)). It excludes nationals of countries listed as sponsors of terrorism.

When the I-94 date comes first

Now reverse it: your B-1/B-2 visa is valid until 2035, but your I-94 says May 1, 2027. You need to leave by May 1 or file to extend before then, because USCIS generally won't approve an extension filed after your stay ran out unless extraordinary circumstances caused the delay (8 CFR 214.1(c)(4)).

Overstaying even a day voids the visa (8 U.S.C. 1202(g)), so you'd usually have to apply for a new one in your country of nationality. Unlawful presence builds, too. More than 180 days of it triggers a 3-year bar on returning once you leave, and a year or more triggers a 10-year bar (8 U.S.C. 1182(a)(9)(B)).

## The main routes to a green card

USCIS sorts green card eligibility into family, employment, special immigrants, refugees and asylees, trafficking and crime victims, abuse victims, and smaller programs such as the diversity visa lottery. Family cases start with immediate relatives of citizens (spouses, unmarried children under 21, and parents of citizens 21 or older); employment cases run through three preference levels plus investors; refugees and asylees can apply after a year. Our guide on how to get a green card covers each route, and the marriage green card steps cover a spouse's case.

When to ask an immigration lawyer which path fits

Most problems here come from timing and intent, and both are easier to fix early. Talk to an immigration attorney if:

• your I-94 date is a few months away and nothing has been filed to extend or change your status;
• you came in as a visitor, student or TN worker and now want to stay, say after a marriage or a job offer;
• you're on a J-1 and don't know whether the two-year home residence rule applies to you;
• you've worked without authorization, stayed past your I-94 date or let your program lapse;
• your stamp has expired and you need to travel for work or a family event.

A lawyer can check your I-94 history against your category's rules and say whether to file here, go through a consulate or wait. Our immigration attorney listings can be narrowed by state and city, so you can compare nearby firms. If you're unsure what help you need, pick "Work visa," "Student visa" or "Green card" in our Immigration Lawyer Match for the type of attorney to look for and a document checklist.

Frequently asked questions

How long can you stay in the U.S. on a tourist visa?

Your I-94 sets the date. Visitors can be admitted for up to a year, and a B-2 visitor issued an I-94 gets at least six months unless an official approves less. To stay longer, file Form I-539 before that date; extensions come in increments of up to six months (8 CFR 214.2(b)).

Is an immigrant visa the same as a green card?

No. An immigrant visa is the travel document a U.S. consulate issues abroad so you can come here to live (8 U.S.C. 1101(a)(16)). You become a permanent resident when CBP admits you on it. The physical green card comes afterward, and unless you're in an exempt group, USCIS won't send it until you've paid the USCIS Immigrant Fee.

Can you switch to a different visa without leaving the U.S.?

Often, through a change of status under 8 U.S.C. 1258, if you're still maintaining your current status. Employers file Form I-129 for work classes such as H-1B; most other changes go on Form I-539. The switch isn't open to, among others, K-1 fiancés, Visa Waiver travelers, or J-1s bound by the two-year home rule without a waiver.

Do you need a visa to visit the U.S. at all?

Not always. Citizens of Visa Waiver Program countries can visit for up to 90 days with an approved ESTA, but they can't extend or change status and they waive most rights to contest removal (8 U.S.C. 1187). Canadians generally don't need a visitor visa, though they do for the E, K, S and V classes (8 CFR 212.1(a)).
