What the governing framework requires

InvestmentVisaLaw.com grounds substantive legal guides in primary authority whenever practical. E-2 analysis principally draws from INA §101(a)(15)(E), 8 C.F.R. §214.2(e), USCIS Policy Manual guidance, 9 FAM 402.9, and the current State Department treaty table. L-1 analysis principally draws from INA §101(a)(15)(L), 8 C.F.R. §214.2(l), USCIS Policy Manual Volume 2, Part L, and 9 FAM 402.12. EB-5 analysis principally draws from INA §203(b)(5), applicable regulations, the EB-5 Reform and Integrity Act, USCIS Policy Manual Volume 6, Part G, current forms and instructions, and binding precedent decisions.

The site uses a hierarchy of legal authority

Immigration guidance is most reliable when the legal conclusion can be traced to the authority that actually governs the issue. InvestmentVisaLaw.com therefore gives priority to primary legal and agency sources rather than relying on other law firm articles, summaries, search snippets, or generalized internet explanations.

AuthorityHow it is used
Immigration and Nationality ActEstablishes the statutory classification, eligibility requirements, and congressional framework.
Code of Federal RegulationsProvides regulatory definitions, filing rules, evidentiary standards, periods of stay, and implementation details.
USCIS Policy ManualProvides current USCIS adjudicative policy for subjects incorporated into the Policy Manual.
Foreign Affairs ManualProvides Department of State guidance used by consular officers in visa adjudication.
Precedent decisionsProvide binding interpretations where designated as precedent.
Forms and instructionsProvide current filing requirements, document requests, editions, fees, and procedural requirements.
Agency alerts and program pagesProvide current implementation guidance, procedural changes, and program specific developments.

Secondary material can help identify an issue, but it should not replace the controlling authority when the statute, regulation, policy manual, FAM, form instructions, or precedent decision directly answers the question.

E-2 treaty investor analysis requires both immigration law and treaty guidance

The statutory basis for treaty investor classification is INA §101(a)(15)(E). The implementing DHS regulation is principally found at 8 C.F.R. §214.2(e).

For visa adjudication abroad, 9 FAM 402.9 is especially important. It addresses treaty nationality, enterprise nationality, investment, commercial risk, substantiality, real and operating enterprises, marginality, developing and directing the business, employees, and intent to depart.

The Department of State treaty table is a separate critical source because E-2 nationality eligibility depends on the country involved and can be affected by country specific footnotes, treaty terminations, grandfathering rules, reciprocal legislation, and territorial provisions.

USCIS guidance governs E classification matters within DHS jurisdiction, including qualifying requests for E status, extensions, and changes of status.

  • Statute: INA §101(a)(15)(E)
  • DHS regulation: 8 C.F.R. §214.2(e)
  • DOS visa guidance: 9 FAM 402.9
  • USCIS policy: Policy Manual Volume 2, Part G
  • Nationality: current Department of State treaty-country table

Review the E-2 Treaty Investor authority guide

L-1 analysis centers on the statute, 8 C.F.R. §214.2(l), USCIS policy, and 9 FAM 402.12

The L classification is created by INA §101(a)(15)(L). Related statutory definitions for managerial capacity and executive capacity appear in INA §101(a)(44).

The detailed DHS regulatory framework appears in 8 C.F.R. §214.2(l). It addresses qualifying organizations, employment abroad, individual petitions, blanket petitions, new offices, L-1A and L-1B requirements, amendments, extensions, and maximum periods of stay.

USCIS consolidated its L-1 adjudicative policy in Volume 2, Part L of the USCIS Policy Manual. USCIS states that the Policy Manual guidance superseded related material previously contained in the Adjudicator's Field Manual and associated policy memoranda.

For consular visa processing, 9 FAM 402.12 addresses individual and blanket L petitions, new offices, qualifying relationships, specialized knowledge, executives and managers, visa issuance, refusals, and periods of stay.

  • Statute: INA §101(a)(15)(L) and relevant definitions
  • DHS regulation: 8 C.F.R. §214.2(l)
  • USCIS policy: Policy Manual Volume 2, Part L
  • DOS visa guidance: 9 FAM 402.12

Review the L-1 authority guide

EB-5 requires attention to both legacy rules and the post-2022 statutory framework

The statutory basis for EB-5 is INA §203(b)(5). Congress materially changed the regional center and investor framework through the EB-5 Reform and Integrity Act of 2022.

The applicable regulatory framework includes 8 C.F.R. §204.6 and related provisions. Current USCIS Policy Manual Volume 6, Part G consolidates agency guidance concerning immigrant investors and must be read together with statutory changes that apply to post-RIA filings.

Current Form I-526 and Form I-526E instructions are especially important for lawful capital and source of funds evidence because the instructions identify documents USCIS expects investors to provide.

Precedent decisions remain important where their holdings continue to apply. Matter of Ho and Matter of Izummi, for example, remain significant to business plan, lawful source, path of funds, at risk investment, and investment structure analysis, subject to later statutory and policy developments.

  • Statute: INA §203(b)(5)
  • Legislation: EB-5 Reform and Integrity Act of 2022
  • Regulation: 8 C.F.R. §204.6 and related provisions
  • USCIS policy: Policy Manual Volume 6, Part G
  • Forms: current I-526, I-526E, and I-829 instructions as applicable
  • Precedent: controlling investor decisions where still applicable

Review the EB-5 authority guide

USCIS and the Department of State may apply related law in different procedural settings

Investor and business immigration often involves more than one federal agency. The same classification can therefore require different sources depending on the procedural stage.

USCIS adjudicates petitions and many requests for immigration status within the United States. The Department of State adjudicates visa applications abroad. CBP makes admission determinations at ports of entry. Each agency operates within its own statutory and regulatory authority.

For example, an L-1 beneficiary may first depend on a USCIS petition approval and later apply for an L visa at a consulate. The FAM expressly recognizes DHS responsibility for individual L petition adjudication while separately describing the consular officer's visa responsibilities.

An E-2 applicant abroad may proceed principally under Department of State visa procedures, while an eligible person already in the United States may pursue qualifying E status procedures with USCIS.

The site therefore identifies whether an authority governs USCIS adjudication, visa issuance, admission, or more than one stage of the process rather than treating all immigration agencies as interchangeable.

Immigration authorities change, so publication dates and review dates matter

Immigration law is not static. Congress can amend the INA. DHS and the Department of State can amend regulations. USCIS can revise the Policy Manual, forms, instructions, and filing procedures. The Department of State can revise the Foreign Affairs Manual and treaty table.

Each substantive InvestmentVisaLaw.com authority page therefore displays a legal review date. That date should represent substantive legal review, not merely a technical change to the website.

When a rule is time sensitive, the article should identify the relevant date or legal framework rather than presenting a historical rule as though it still governs new filings. EB-5 is a clear example because investment amounts and regional center rules differ materially depending on the filing framework.

The official government source should control when it has changed after the review date shown on a page.

Primary authorities are linked so readers can verify the legal proposition

Substantive guides on this site include a primary authorities section identifying the government sources used in the legal analysis.

Where useful, the body of a guide also links directly to related authority pages or specialized explanations. This allows a reader to move from the specific answer to the broader legal framework without requiring every article to reproduce the entire statute or regulation.

Legal propositions should be distinguishable from practical observations. A statute, regulation, FAM provision, or policy statement should not be described more broadly than the source actually supports.

The site's goal is therefore not merely to provide an answer. It is to provide enough authority and explanation that the answer can be checked, understood, and updated when the governing law changes.

Substantive pages identify the attorney responsible for legal review

Substantive legal guides are reviewed by Peter Messersmith, Senior Immigration Attorney at The Messersmith Law Firm, P.A.

Mr. Messersmith's public professional biography states that he has held an unrestricted Illinois law license since November 2002, has practiced law continuously since 2002, and limits his practice to immigration law.

The reviewer identification is intended to distinguish legal review from anonymous website publishing. It does not mean that a general educational article constitutes individual legal advice or predicts the outcome of a particular immigration matter.

The site prioritizes primary authority including the Immigration and Nationality Act, federal regulations, USCIS Policy Manual, Foreign Affairs Manual, government forms and instructions, official agency guidance, and binding precedent decisions.

Is the Foreign Affairs Manual legally the same as a statute or regulation?

No. The FAM is Department of State guidance used in consular administration. The site distinguishes it from statutes and regulations while recognizing its importance to visa adjudication.

Why does the site link to USCIS form instructions?

Current form instructions can contain important filing and documentary requirements, including detailed evidence USCIS expects in particular classifications.

Why do pages show a legal review date?

Immigration statutes, regulations, policy, forms, and agency guidance can change. The review date indicates when the substantive legal content was last reviewed rather than when a technical website change occurred.

Who reviews the substantive legal guides?

Substantive legal guides are reviewed by Peter Messersmith, Senior Immigration Attorney at The Messersmith Law Firm, P.A.

Does a cited government source guarantee a particular case result?

No. Immigration eligibility is fact specific, and agency adjudication depends on the complete record and the governing law applicable to the individual matter.
