Official U.S. Immigration Sources: Agency and Document Map

Use the agency, form, notice, court, consular post, visa bulletin, and licensing record that controls the question instead of relying on a third-party summary.

Editorial responsibility

How source checking is recorded

Each deep guide lists the official pages used for the claims and shows the source-check date. A form page supports form mechanics; a policy or practice manual supports agency procedure; a case-specific notice or order remains controlling for the individual file.

  • Search snippets and third-party summaries are starting points, not controlling sources.
  • The site avoids freezing changeable fees, form editions, filing addresses, and processing times into undated prose.
  • A source-check date is not an attorney-review date and is not represented as one.
  • When an official page is blocked to automated checks, the URL remains flagged for periodic human verification.

Quick answer

What this page can help you verify

U.S. immigration information is distributed across several agencies. USCIS handles many benefit applications and petitions; the Department of State manages visas, the National Visa Center, consular posts, and the Visa Bulletin; EOIR runs immigration courts and the Board of Immigration Appeals; CBP controls inspection and I-94 records; ICE handles enforcement and detention functions; and the Department of Labor administers labor-condition and labor-certification programs. [1] [2] [3]

A source is useful only if it controls the issue being researched. A USCIS form page may provide the current edition, fee, and filing address, while the Policy Manual explains USCIS adjudication policy. An immigration court scheduling order controls that case's deadline, and an embassy page may add post-specific interview instructions. Save the page title, URL, access date, and the actual notice or instruction used. [2] [3]

Use this source verification guide to prepare records and questions about source verification review. It provides general information, does not decide eligibility, and does not create an attorney-client relationship.

Decision map

Questions that control the analysis

For source verification review, identify the legal branch before collecting documents. Begin with controlling agency, document level, case-specific instruction; then match each unresolved point to a reliable record and the cited official instruction.

CheckpointWhat to verify
Controlling agencyStart with the agency named on the receipt, notice, charging document, refusal sheet, approval, court order, or labor filing. [1]
Document levelUse the current form page and instructions for filing mechanics, then the statute, regulation, policy manual, or practice manual for the governing rule. [2]
Case-specific instructionTreat the person's notice, scheduling order, NVC message, and consular post instruction as separate controls that a general page may not replace. [3]
CurrencyCheck edition dates, alerts, page updates, fee schedules, filing addresses, visa bulletin month, court changes, and agency announcements before acting. [4]
Source trailRecord what proposition each source supports, when it was checked, and whether a later official instruction superseded it. [5]

Process

A practical file-review sequence

  1. Read the government document in the file and identify its agency, form, receipt or case number, deadline, and action requested. [2]
  2. Open the official form or program page directly and confirm current instructions, edition, fee, filing location, and alerts. [3]
  3. Use the governing policy or practice manual for adjudication and procedure, then check court, NVC, post, or field-office instructions specific to the case. [4]
  4. Save or print the controlling page and note the access date; do not rely on a search-result snippet, cached summary, or old PDF alone. [5]
  5. When sources conflict or the legal consequence is significant, pause and have qualified counsel determine which authority controls the facts and date involved. [6]

Evidence plan

Records to organize before legal review

The evidence plan for source verification review should connect the controlling facts to uscis file, consular file, court file. Volume alone does not prove that a filing, response, or defense satisfies the applicable rule.

  • USCIS file: Form page, current instructions, receipt and notices, Policy Manual chapter, case status, processing inquiry, and address update.
  • Consular file: Petition approval, NVC case, CEAC messages, Visa Bulletin, reciprocity schedule, embassy instructions, DS form, and refusal sheet.
  • Court file: NTA, hearing notice, scheduling order, EOIR Policy Manual, court directory, ECAS or Respondent Access record, decision, and appeal information.
  • Border or detention file: I-94, CBP travel or FOIA record, ICE detainee locator, custody decision, release conditions, and enforcement documents.
  • Employment and representative file: DOL FLAG or wage record, official state bar profile, DOJ accreditation roster, discipline check, and written engagement agreement.

Record control

Build a chronology that another professional can audit

For source verification review, create one working table with five columns: date or period, event, document that proves it, unresolved conflict, and next action. Use exact dates from primary records where possible. Label estimates and record what would confirm them. Show conflicting records instead of silently choosing one before a signed filing or interview adopts that version.

For this guide, mark when each controlling issue began or changed: controlling agency, document level, case-specific instruction, currency, source trail. [1] The purpose is to see sequence and legal posture, not to create a persuasive story before the facts are complete. A petition approval, departure, arrest, marriage, filing, denial, court order, employer change, or agency notice can alter the analysis from that date forward.

Link every important event to the most reliable available record. Organize the file under these evidence groups: uscis file, consular file, court file, border or detention file, employment and representative file. Keep the original, a readable working copy, and any certified translation together. Record who created the document, when it was created, and whether the government has already received a different version.

For source verification review, add a source-control row for each legal or procedural assumption: official page title, URL, date checked, and any case-specific notice or order that supersedes the general page. [4] Before acting, flag every conclusion that still depends on memory, an unofficial summary, an incomplete record, an old form, or an unanswered question for counsel.

Risk check

Common mistakes that can change the case

  • Using a third-party article to choose a form edition, fee, filing address, deadline, or visa-availability date. [3]
  • Assuming USCIS, immigration court, NVC, embassy, CBP, ICE, and DOL procedures are interchangeable. [4]
  • Relying on a saved PDF after an official web page, notice, court order, or form edition has changed. [5]
  • Treating a processing-time estimate or case-status message as a legal extension of a printed deadline. [6]
  • Quoting an official page without connecting it to the person's category, jurisdiction, facts, and procedural posture. [1]

Consultation preparation

Questions to take to a qualified lawyer

A consultation about source verification review is more useful when it begins with the controlling document, a dated chronology, and the complete prior record. Take the following questions and note where the lawyer's answer depends on missing evidence.

  1. Which agency and document currently control the question?
  2. Is the source about filing mechanics, adjudication policy, court procedure, visa availability, or case-specific instructions?
  3. When was the page or manual updated and when was it last checked for this file?
  4. Does a notice, order, embassy instruction, or newer authority supersede the general page?
  5. Is the issue sufficiently fact-sensitive or high-risk that source reading should be followed by qualified legal advice?
