  "title": "Nigeria Application Form for Visa/Entry Permit (Form Imm. 22)",
  "description": "Apply for a Nigerian visa/entry permit through the Nigeria Immigration Service (NIS)'s standard \"Form Imm. 22 — Application Form for Visa/Entry Permit\", scoped to embassy/consular use abroad, opening Nigeria's Visa vertical (3 of 6, alongside Business Formation and Taxes; continuing the Nigeria research thread from GOV-2551/GOV-2553). This specimen is confirmed live at three independently operated mirrors as of 2026-07-12, two of them directly re-fetched this cycle: the Embassy of Nigeria in Vietnam's own government domain (nigeriaembassy.org.vn, HTTP 200, application/pdf, 373,872 bytes, matching the issue's own citation exactly) — a simplified 2-page, 25-numbered-question edition, used as this schema's primary citable `source` since it is the only own-government-domain copy — and a Nigerian-Embassy-Washington-DC-letterheaded copy hosted on a third-party visa-services domain (samspassport.com, HTTP 200, application/pdf, 43,156 bytes), a fuller 3-page, 31-numbered-question edition that itself prints the form's official designation \"Form Imm. 22\" and is used here as the base for field coverage per this cycle's scope. A third cited mirror (nigerianvisaservices.com) was also directly re-fetched this cycle and returned a live `application/pdf` response (88,509 bytes) on every attempt; it is not byte-identical to the DC/Washington copy (a separately re-typeset rendering, sha256 differs), but independent text extraction confirms it carries the same \"Form Imm. 22\" content and item numbering, corroborating the DC/Washington edition as NIS's stable standard distributed across missions rather than a single embassy's one-off variant. Both directly-verified editions are flat, print-and-hand-fill specimens (0 AcroForm widgets), completed by hand and mailed to a Nigerian diplomatic mission together with supporting documents and a money-order processing fee. Independent extraction of both editions' full printed text found the two are NOT a strict superset/subset pair as initially characterized: the fuller DC/Imm.22 edition indeed adds substantial content the simplified Vietnam edition omits (number-of-entries, funds available, employment/spouse-in-Nigeria particulars, prior Nigerian-visa history, immigration/criminal/health-history screening, countries lived-in/visited in the last 5 years and 12 months, and the fee/attachments schedule), but the Vietnam edition also independently asks 6 items the DC edition omits entirely (e-mail address, complexion, academic qualifications, source of sponsorship, and a mission-localized \"reference in [country]\" name/address/telephone). This schema models the union: the DC/Imm.22 edition's 31 numbered items supply the base structure (86 of this schema's 93 `fields[]` entries, including three bounded repeating tables — a 3-slot prior-Nigeria-visit table and two 4-slot countries-lived-in/visited tables, per this registry's established bounded-repeating-group convention), plus the Vietnam edition's 6 edition-unique items (modelled as independently optional fields, since a specimen's omission of a question this registry has directly verified another edition asks is not evidence the question is inapplicable). 9 `documents[]` entries capture the photograph requirement (printed on both editions), the DC edition's page-3 attachments-and-fee schedule (original passport, letter of invitation, prepaid return mailer, an online visa-fee payment, a $20 money-order processing fee, an optional $65 expedited-service fee), its under-16 accompanying-child document bundle, and its wet-ink certification statement.

    "notes": "GovSchema Standard Research cycle GOV-2561, continuing Nigeria's research thread from GOV-2551 (parent research issue) and GOV-2553 (Taxes, 2/6). Independently re-fetched both citable mirrors directly: nigeriaembassy.org.vn (HTTP 200, application/pdf, 373,872 bytes, Last-Modified Sat 21 Nov 2020, matching the issue's own citation exactly) and samspassport.com (HTTP 200, application/pdf, 43,156 bytes, Last-Modified Tue 29 Oct 2019, 3 pages, 31 numbered questions matching the issue's description, and printing the form's own designation \"Form Imm. 22\" at its header). The third cited mirror (nigerianvisaservices.com) was independently re-fetched on a later pass this same cycle (both with and without a browser-like User-Agent) and returned a live `application/pdf` response (88,509 bytes, sha256 8b60aceaaa963eb8ad9690e74613b5cf9118baf6a94af60eb4989b127a2ba544, Last-Modified Sat 30 Sep 2017) each time — the earlier Cloudflare-challenge observation is disclosed in VERIFICATION.md as a transient failure, not a genuine access gate. Its content is not byte-identical to the DC/Washington copy (a separately re-typeset rendering with different character spacing, consistent with OCR/re-layout rather than a raw file copy), but a fresh pdfjs-dist text extraction confirms it carries the same \"Form Imm. 22\" title, item numbering, and full item text as the DC/Washington copy, corroborating it as a third independent distribution of the same underlying NIS form rather than an unrelated document. pdfjs-dist (legacy build, v3) getAnnotations() confirms 0 Widget annotations across both directly-verified editions' pages — flat, print-and-hand-fill forms, consistent with this registry's rw/dgie/visa-application precedent. getTextContent() (position-sorted by transform x/y) was used to read each edition's full printed text directly. Independent side-by-side comparison of the two editions' numbered items found the issue's characterization of the DC edition as a strict superset of the Vietnam edition does not hold exactly: while the DC edition (31 items) does add substantial content the Vietnam edition (25 items) omits, the Vietnam edition also independently asks 6 items the DC edition omits entirely (e-mail address, complexion, academic qualifications, source of sponsorship, and a mission-localized reference-in-country name/address/telephone) — corrected and disclosed in VERIFICATION.md rather than silently adopting the issue's framing. This schema models the union, using the DC edition's 31-item structure (which prints the form's own \"Form Imm. 22\" designation) as the base for 86 of 93 fields[] entries, plus the Vietnam edition's 6 edition-unique items as independently optional fields. Conformance run: 2 valid mock scenarios (0 errors each) and 5 mutation-control fixtures (exactly 1 error each) using a disposable validate_instance.mjs script (not committed) implementing this schema's own required/requiredWhen grammar plus ajv for the static JSON Schema subset — see VERIFICATION.md for the full write-up."
