What this page does. Permanent residence, the status commonly called a green card, can be reached by more than a dozen separate legal routes. Each has its own eligibility rules, its own petition or application, and its own place in the annual numerical limits. This page maps those routes so that the relevant one can be identified quickly. Every entry is an outline only; the linked pages carry the detail.
How the tables are organized. Routes are grouped into five families: family relationships, employment, humanitarian and protection, other statutory routes, and routes now closed to new applicants. Within each table the column headed Annual limit is often the most useful, because it explains why two equally strong cases can wait very different lengths of time. A route with no numerical limit produces no queue; a route with a limit produces a queue that is divided further by country of chargeability.
Qualifying is not the same as receiving. Every route below establishes eligibility for an immigrant classification. Obtaining the status itself then requires either adjustment of status within the United States under 8 U.S.C. § 1255 or immigrant visa processing at a consular post abroad, and admissibility must be established either way. Approval of a petition confers a place in line, not a grant of permanent residence.
Where a link is missing. A dash in the final column means this site does not yet carry a page devoted to that route.
Family relationships. Two distinct systems operate here. Immediate relatives of United States citizens are exempt from the annual numerical limits altogether, so no visa queue forms for them. Everyone else falls into one of four numbered preferences under 8 U.S.C. § 1153(a), each with its own annual allotment and each subject to per-country chargeability. A child adopted in accordance with 8 U.S.C. § 1101(b)(1)(E), (F) or (G) counts as a child for these purposes, so intercountry adoption feeds into the immediate relative and preference categories below rather than forming a separate route of its own. The family-based immigration page introduces the process in more detail.

Employment. The employment-based system divides a worldwide level of 140,000 visas under 8 U.S.C. § 1151(d) among five preferences set out at 8 U.S.C. § 1153(b). The first preference is reserved for those whose record speaks for itself and requires no test of the domestic labor market. The second and third preferences ordinarily require a labor certification establishing that no able, willing and qualified domestic worker is available, with a national interest waiver as the principal exception. The employment-based immigration page introduces the system as a whole.

Humanitarian and protection routes. These routes begin with a protection decision rather than a petition by a relative or an employer. Most of them sit outside the preference system entirely, which is why they generate no visa queue, and several of them arise in the course of removal proceedings rather than before an agency. The asylum page covers that route in more depth.

Other statutory routes. The remaining routes do not fit the family or employment pattern. Some are lotteries, some reward long presence, some restore a status that lapsed, and some exist only because Congress legislated for a particular group. They are gathered here because a reader who does not recognize a route in the earlier tables should look through this one before concluding that none applies.
Other statutory routes to permanent residence| Route | Who it is for | Legal basis | Annual limit | More on this site |

| Diversity visa lottery | Nationals of countries with historically low rates of immigration to the United States who meet the education or work experience requirement.

| Registry | Those who entered the United States before January 1, 1972 and have resided here continuously since, subject to good moral character and the statutory bars. The cut-off is fixed in the statute and does not advance with time. | 8 U.S.C. § 1259 | Not counted against the preference allotments. | — |
| Returning resident | Permanent residents whose stay abroad exceeded the period their documentation covers, but whose absence was caused by circumstances beyond their control and who did not abandon residence. | 8 U.S.C. § 1101(a)(27)(A), applied through 22 C.F.R. § 42.22 | None.

Eligibility turns on the wording of each statute rather than on any general rule. | Separate public laws outside title 8 of the United States Code | Set by the individual statute. | — |
| Adjustment despite a status bar | Not a category of its own. It allows certain people who could not otherwise adjust inside the United States to do so, where a qualifying petition or labor certification was filed for them by the statutory cut-off. | 8 U.S.C. § 1255(i) | Not applicable. The underlying category supplies the limit. | Adjustment of status |
Routes closed to new applicants. Two legalization programs still appear in the statute and are still encountered in older files, but neither accepts new applications. They are listed so that a reader who finds a reference to them elsewhere can place them correctly rather than mistake them for a current option.
Routes no longer open to new applicants| Route | What it was | Legal basis | Status |
|---|
| General legalization | Legalization for those who had resided unlawfully in the United States since the qualifying date set by the Immigration Reform and Control Act. | 8 U.S.C. § 1255a | Closed. The filing period has long expired, and residual cases arise only through litigation. |
| Special agricultural workers | Legalization for those who had performed qualifying seasonal agricultural work during the statutory period. | 8 U.S.C. § 1160 | Closed. No new applications are accepted. |
