Underlying pathway status
This site has not yet verified through official materials whether this pathway is currently available; the existence of a code is not used to presume that it is open or closed.
Not all of the following working fields have completed legal review. See the newly added verification for the current status of the pathway; unverified fields, such as translated names and legal authorities, are not thereby elevated to verified status, nor does this constitute individualized legal advice.

Verification of a Newly Added Pathway:Mixed code statusStatus not verified
This site has not yet verified through official materials whether this pathway is currently available; the existence of a code is not used to presume that it is open or closed.
Status recorded at the time of the original snapshot (not a conclusion about current status)
- The source does not provide an active status; whether the status can still be newly obtained requires item-by-item verification of the governing legal authority.
- Already retired when the AFM was archived / historical definition; no longer newly issued under that former definition
Fields that were unverified at the time of the original snapshot remain unchanged. See the newly added pathway verification for current status; other fields are not thereby elevated to verified status.

Original Snapshot Notes (Not Current Status)
The OHSS page does not provide an active/status field; the existence of a source does not mean the pathway is currently open; the same code also appears in the current consular immigrant visa table in 22 CFR 42.11; identical-form/normalization collisions exist, and identification must take into account the period, legal authority, and source records.

Original Snapshot Notes (Not Current Status)
The same code may recur in different eras or under different acts; this record is retained according to its legal context; independent QA has placed it in the manual review queue; no silent deduplication or rewriting is permitted; identical-form/normalization collisions exist, requiring identification in conjunction with the era, legal authority, and source record
11General Limitations for Existing Holders
- Discontinuation of a code does not automatically revoke LPR status previously lawfully obtained; an individual's status still depends on subsequent facts.
This page compiles code reference materials. It does not constitute legal advice or determine any individual's current immigration status.
