Many E-2 investors learn quickly that “how much money is enough” is not answered by a single dollar figure.

Instead, adjudicators often focus on whether the investment is proportional to the cost of buying or creating the specific business, and real-world cases show how that analysis plays out in practice.

What the E-2 proportionality test really means

The E-2 Treaty Investor visa is built around an idea that sounds simple but becomes nuanced in real filings: the investor must place a substantial amount of capital at risk in a bona fide U.S. enterprise. For many investors, the most confusing part is that “substantial” is not a fixed number.

In practice, officers and adjudicators frequently use what is commonly called the proportionality test. The analysis looks at the relationship between the amount invested and the total cost of purchasing an existing business or starting the new enterprise to an operational stage.

The proportionality test is referenced in U.S. government guidance rather than presented as a strict mathematical rule. The key is the story the numbers tell: does the investor have enough skin in the game, relative to what this business realistically costs?

For official context, readers can review the Department of State’s overview of the E visa category at travel.state.gov and USCIS’ E-2 page at uscis.gov.

Why proportionality matters more than a “minimum investment” myth

Online forums often repeat that an E-2 requires $100,000, $150,000, or $200,000. Those figures can be common in some industries, but they are not a legal minimum. Proportionality is one reason the myth persists. Investors see patterns in approvals and assume the pattern is a requirement.

The proportionality test helps decision-makers answer two practical questions:

• Is the investment large enough to make the business viable and not marginal?
• Is the investor financially committed to the success of the enterprise?

Because the test is tied to the economics of a specific business, a high percentage investment may be expected when the total cost is relatively low. When the total cost is higher, a lower percentage might still be considered substantial, as long as the absolute amount and the overall plan show real commitment.

How the proportionality test is typically evaluated

Although each case is fact-specific, proportionality usually starts with a denominator and a numerator.

The denominator: total cost to buy or start the business

The “total cost” is often demonstrated through:

• Signed purchase agreements and closing statements for an existing business acquisition
• Franchise disclosure documents and build-out estimates for a franchise
• Equipment quotes, contractor bids, commercial leases, and vendor invoices for a startup
• Working capital projections that match the industry and the business plan

One common mistake is using a rough estimate rather than evidence. If the business is said to require $120,000 to launch, but the file contains only a spreadsheet with rounded numbers, it can be harder to anchor proportionality.

The numerator: what the investor has already invested or is irrevocably committed to

For E-2 purposes, the investment generally must be at risk and committed to the enterprise. Officers often look for funds that have already been spent or are locked into binding obligations tied to the business.

This can include:

• Funds transferred to a U.S. business bank account and then spent on business expenses
• Paid invoices and receipts for equipment, inventory, software, marketing, and professional services
• Non-refundable deposits and signed contracts that create an irrevocable commitment

Parking cash in a bank account without a clear spend path can look less persuasive than documented expenditures and contracts. The proportionality test is not only about the percentage, it is also about the credibility of the operating plan.

Real E-2 case scenarios that show proportionality in action

The scenarios below are written as representative examples. They are not tied to a specific client’s confidential facts, but they reflect common patterns seen in E-2 practice. Each one shows how proportionality can strengthen or weaken an application.

Scenario 1: A low-cost service business with a high percentage investment

An investor from a treaty country starts a home services company offering residential painting and light renovations. The business model is lean: a small office, basic equipment, a vehicle lease, insurance, branding, and initial marketing.

They estimate that it costs $45,000 to launch properly. They invest $40,000 before applying, with documented spending that includes equipment purchases, licensing and insurance, website development, marketing deposits, and a commercial mailbox and coworking setup.

From a proportionality perspective, the investment is close to the full startup cost. Even though $40,000 sounds “low” compared to internet rumors, the percentage is strong. The record also shows that the business can begin operating immediately.

What strengthens the proportionality argument here is that the total cost is realistic for the industry, and the investor has committed most of it in verifiable ways.

A question an officer might still ask is whether the enterprise is marginal. If the business plan shows only enough income to support the investor and no plan to hire, proportionality alone may not carry the case. The numbers must connect to growth and job creation, even if modest.

Scenario 2: A café startup where the percentage looks high but the business is not ready

Another investor plans to open a small café. They invest $90,000 and claim the total startup cost is $110,000. On paper, that looks very proportional.

But the documentation reveals a major gap: no signed lease, no build-out bids, and no health department or permitting timeline. Much of the $90,000 sits in a business account with no invoices, and the business plan does not explain how the café will open without a secured location.

In this scenario, the proportionality percentage may be high, but the investment can look less committed and the business can look speculative. Proportionality is not meant to reward a large deposit if the enterprise is not truly ready to launch.

How could this scenario improve? The investor could secure a lease with appropriate contingencies, obtain contractor bids, show equipment orders, and document a clear spend schedule tied to opening. The same $90,000 becomes far more persuasive when it is clearly at risk and connected to operations.

Scenario 3: Buying an existing business at a fair price with strong evidence

An investor buys an existing tutoring center for $150,000. The purchase agreement is signed, the escrow closes, and the seller provides financial statements, a customer list summary, and a training and transition plan.

The investor pays the full purchase price and adds $30,000 in working capital for marketing and staff expansion. Their total investment is $180,000 against an acquisition cost of $150,000 plus reasonable post-acquisition operating needs.

Proportionality is usually straightforward in this kind of acquisition case because the denominator is documented by a real market transaction. The investor can show the business is already operating and can support employees. The file has clarity, which often makes the proportionality story easy to follow.

A practical tip here is that the investor should avoid presenting an inflated “total cost” that is not supported by the deal structure. Officers tend to trust clean purchase documentation more than aspirational projections.

Scenario 4: A higher-cost business where a lower percentage can still work

An investor enters a specialty manufacturing space requiring expensive machinery, facility upgrades, and regulatory compliance. The total cost to launch is $900,000. The investor puts in $450,000 initially, with contracts signed for equipment and a facility lease, and the remainder is planned through revenue plus a commercial loan secured by business assets.

A 50 percent investment is not “small” in absolute terms, but the percentage is lower than what might be expected for a very small startup. The proportionality logic often recognizes that as the total cost rises, the investor is not always expected to fund 90 to 100 percent. What matters is whether the investment is still substantial and the investor is committed.

This type of scenario requires careful documentation and a coherent business plan. It also raises questions about whether borrowed funds are secured by the investor’s personal assets or by the enterprise. While loans can sometimes be part of the capital picture, the case must still show that the investor’s funds are genuinely at risk and that the enterprise is not undercapitalized.

When officers assess proportionality here, they usually want to see that the initial capital is enough to begin meaningful operations and that the remaining funding path is credible, lawful, and well-documented.

Scenario 5: A franchise where the “real cost” is higher than the franchise fee

A common E-2 visa USA scenario involves a franchise. An investor might see a franchise fee of $40,000 and assume that is the key number. In reality, the total cost often includes build-out, equipment, signage, initial inventory, training, technology systems, insurance, and working capital.

Consider a franchise with an estimated total startup cost of $220,000. The investor invests $120,000 and files quickly, showing they paid the franchise fee and some deposits but have not signed a lease or begun construction.

Proportionality becomes tricky because the denominator is not the franchise fee. The denominator is the full cost to open and operate. If the file treats $40,000 as the benchmark, the investor may unintentionally understate what “substantial” means for that enterprise.

A stronger approach is to document the franchise’s itemized startup estimate, match it with real bids and lease terms, and show that the investor has committed enough of that total to make opening imminent. Proportionality works best when the case shows the enterprise is truly moving toward launch, not just reserved in theory.

Scenario 6: An E-2 startup with heavy spending, but weak source of funds documentation

Sometimes the proportionality story looks perfect, but the case still struggles because the investor cannot clearly prove lawful source of funds. An investor might spend $130,000 on a digital marketing agency startup, hire staff, and show impressive client projections. The proportionality ratio might be strong because the total cost is $150,000 and most of it has been spent.

But if the investor cannot document where the funds came from, such as business earnings, salary, dividends, property sale, or a gift with documentation, the investment may not be credited in the way they expect. Proportionality does not replace source-of-funds analysis. Both must be satisfied.

In practice, clean records matter. Bank statements, tax documents, sale contracts, payroll records, and wire transfer trails can turn a good proportionality case into an approvable one.

Common proportionality pitfalls that trigger E-2 problems

Proportionality issues often arise from avoidable gaps rather than the dollar amount itself.

• Understating the true startup cost: If the plan ignores permits, build-out, insurance, or working capital, the proportionality ratio may look better than reality, and that can undermine credibility.
• Holding funds without committing them: Cash sitting in an account can look like intent rather than action. Officers often want to see expenditures and binding commitments.
• Spending that is not clearly business-related: Vague payments or mixed personal and business expenses can make the investment harder to credit.
• Relying on overly optimistic projections: A business plan that assumes rapid growth without showing how the capital supports that growth can make the investment look insufficient.
• Not matching industry norms: If comparable businesses typically require higher upfront capital, the investor should explain why their plan is leaner and still viable.

Actionable ways to build a stronger proportionality argument

An E-2 application becomes more persuasive when the numbers and documents support a simple narrative: the investor has invested enough, in the right places, to open and operate a real business that can grow.

Show a credible total cost, supported by evidence

Investors can strengthen the denominator by using:

• Signed leases or letters of intent where appropriate
• Contractor bids and build-out estimates tied to the actual location
• Equipment quotes that match the services or products offered
• Vendor agreements and software subscriptions that show operational readiness

When the costs are well-supported, the proportionality discussion becomes less subjective.

Make “at risk” easy to see

Officers should not have to guess whether the funds are committed. Paid invoices, non-refundable deposits, and executed contracts are usually more compelling than a promise to spend later.

It can also help when the business bank account is used cleanly, with clear descriptions and accounting categories, so the record reads like a real company file rather than a personal bank history.

Explain why this amount is enough for this specific business

Proportionality is not only arithmetic. It is persuasion grounded in evidence. A strong case often includes a brief explanation connecting the investment to:

• Operational milestones, such as opening day, marketing launch, and first hires
• Capacity, such as how many clients can be served and with what staffing
• Risk, such as why the funds cannot be easily recovered if the business fails

How proportionality interacts with other E-2 visa requirements

It helps to remember that proportionality is a tool used to evaluate the substantial investment requirement, but it does not stand alone. The E-2 visa requirements also include, among other points:

• The investor must be a national of a treaty country
• The enterprise must be real and operating, or at least very close to operating
• The investor must develop and direct the business, often shown by ownership and a managerial role
• The business must not be marginal, meaning it should have the capacity to generate more than just a minimal living for the investor over time

For readers exploring US immigration through investment, it is also important to distinguish E-2 from other paths such as the EB-5 Immigrant Investor Program, which is a separate category with different standards and leads to permanent residence when eligible. The U.S. government’s EB-5 overview is available at uscis.gov.

Proportionality and the “startup visa USA” conversation

Many entrepreneurs search for a “startup visa USA” and end up learning that the E-2 is often the closest fit for treaty-country founders who can invest and actively run a U.S. business. That makes proportionality especially relevant for early-stage companies where spending can be flexible.

A software or services startup may not need expensive equipment, but it still needs credible capital deployment. The file should clearly show what the money accomplishes, such as product development, initial hires or contractors, customer acquisition, compliance, and operating runway.

A useful self-check is this: if the investor had to explain the budget to a skeptical business partner, would the spending plan make sense, and would the partner believe the company can launch and grow with the available capital?

Questions investors should ask before filing an E-2 based on proportionality

Before submitting an E-2 visa USA application, it helps if the investor can answer a few practical questions clearly:

• What is the real total cost to buy or start this enterprise to an operating stage, supported by documents?
• How much has already been spent or committed, and can each major transaction be proven with invoices and bank records?
• What happens next operationally in the first 30, 60, and 90 days, and how does the investment fund those steps?
• Does the business plan show growth beyond supporting only the investor, such as hiring, contractors, or expansion?

These questions often reveal whether the proportionality narrative is truly ready or whether the case needs more documentation and preparation.

Why real-world preparation beats chasing a target number

The proportionality test rewards alignment between the business model and the investment. A lower-cost business may need a higher percentage commitment. A higher-cost business may justify a lower percentage if the absolute investment is still substantial and the plan is credible.

In E-2 cases, clarity wins. When the total cost is documented, the funds are clearly at risk, and the business is ready to operate, proportionality becomes a persuasive part of a larger story about a serious investor building a real U.S. enterprise.

If an investor is weighing an investor visa USA strategy, a practical next step is to ask: does the evidence show a business that is actually opening, hiring, and serving customers, or does it mainly show money set aside and plans for later?

That single question often determines whether proportionality supports the application or exposes the weak spots that should be fixed before filing.
