E-2 Visa Cover Letter: What to Include and Why It Matters

The cover letter is a legal memorandum, usually written by the applicant's immigration attorney, that walks through each eligibility criterion under 9 FAM 402.9 (for consular posts) or 8 CFR 214.2(e) (for USCIS change-of-status filings). It is not a marketing document and it is not a duplicate of the business plan. Its job is to cite the facts in the application, match them to the specific regulatory language, and preempt the objections an adjudicator is likely to raise.

Some applicants submit a short transmittal letter that simply lists the enclosed documents. That approach leaves the adjudicator to draw their own conclusions, which is risky. A proper cover letter argues the case, cites the evidence by exhibit number, and walks through the treaty investor criteria in a logical order.

Under 9 FAM 402.9-4 and 8 CFR 214.2(e)(2), the E-2 applicant must establish five things: (1) the applicant is a national of a treaty country; (2) the enterprise is a real and operating commercial enterprise; (3) the investment is substantial; (4) the investment is at risk; and (5) the applicant will develop and direct the enterprise. A cover letter that skips or glosses over any one of these elements creates an opening for a denial.

Each section of the cover letter should correspond to one of these elements and should cite the specific exhibits that prove it. If the investment source is a combination of personal savings and a commercial loan, the cover letter should explain each source separately, cite the bank statements, cite the loan documents, and explain how the funds were traced to the applicant's personal funds or to legitimate business debt, not a gift or unsecured loan from a third party.

• Treaty nationality: certified copy of passport, certificate of citizenship, or dual-national analysis if relevant
• Bona fide enterprise: business registration, lease, licenses, evidence of operational activity or committed capital
• Substantial investment: total investment figure, proportionality calculation relative to the business value
• At-risk funds: irrevocability documentation, escrow release conditions, evidence capital is committed
• Develop and direct: organizational chart, ownership percentage, officer role, day-to-day management description

The treaty nationality section is often just one paragraph, but it needs to be precise. The cover letter should identify the specific treaty between the United States and the applicant's home country, cite the country-specific note in 9 FAM 402.9-2, and reference the passport or citizenship documentation enclosed. If the applicant holds dual nationality, the cover letter must address which nationality qualifies and why, since not every dual national can use both passports for E-2 purposes.

For corporate investors applying through an E-2 enterprise, the cover letter must also establish that the enterprise itself is at least 50 percent owned by nationals of the treaty country. This often requires tracing ownership through holding companies or partnerships, which the cover letter should explain clearly.

The investment section is where most cover letters either earn their value or fail. The Department of State uses a proportionality test rather than a fixed dollar threshold: the investment must be substantial in relation to the total cost of purchasing or establishing the enterprise. Under 9 FAM 402.9-4(B)(4), a lower-cost business requires a higher percentage of funds invested, while a higher-cost business may qualify with a lower percentage. The cover letter should present this calculation explicitly, show the total business valuation or startup cost, show the amount invested, and state the resulting percentage.

The cover letter should also distinguish between funds already committed and funds pledged for future use. Funds that are irrevocably committed to the enterprise, even if not yet spent on business expenses, count as invested under the at-risk standard. Funds sitting in a personal bank account with no binding commitment to the enterprise do not. This distinction matters for startups, where much of the capital may be earmarked for future payroll, equipment, or inventory.

The develop-and-direct requirement is the one adjudicators scrutinize most closely for investors who own exactly 50 percent of the enterprise or who are hiring a general manager to run day-to-day operations. The cover letter should explain the applicant's specific management role: what decisions they make, what operational authority they hold, and how their ownership structure gives them effective control. For a sole owner or a majority owner, this section is usually straightforward. For a minority owner or a co-investor arrangement, the cover letter needs to show that the applicant has either majority ownership or a supermajority voting structure that gives them effective control.

If the applicant is an employee of the E-2 enterprise rather than the investor, the cover letter must establish that the employee is coming to perform executive, supervisory, or essential skills duties under 8 CFR 214.2(e)(8). The analysis is different from the investor analysis and should be argued separately.

Under 9 FAM 402.9-4(B)(5), a marginal enterprise is one that does not have present or prospective capacity to generate income significantly above a living wage for the investor and their family. This is a common denial reason, and the cover letter should address it affirmatively even if the consular officer has not raised it yet.

The cover letter should point to the financial projections in the business plan, explain the methodology used to produce them, and identify the specific line items (projected revenue, payroll, net income) that demonstrate the enterprise will go beyond supporting the investor's personal income. If the business will create jobs for U.S. workers, that is strong evidence of non-marginality, and the cover letter should cite the staffing projections from the business plan directly.

A well-organized exhibit list makes the adjudicator's job easier and reduces the chance they miss a critical piece of evidence. The cover letter should number every exhibit, describe what it is in one sentence, and explain what it proves. For example: "Exhibit 7: Commercial Lease Agreement, 2,400 sq ft retail space, Scottsdale, AZ, signed March 2026, demonstrating irrevocable commitment of $92,000 in leasehold improvements." That framing is more useful than just labeling it "Exhibit 7: Lease."

For USCIS I-129 petitions, the cover letter is part of the petition package and should follow the order of the form. For DS-160 and consular filings, the cover letter typically leads the package and the exhibits follow in the order they are cited. Either way, consistency between the cover letter's citations and the actual exhibit tabs prevents the adjudicator from having to search for the documents you are pointing to.
