IN THIS GUIDE · A minority stake in a calibration business, and the ownership arithmetic that decides the whole case
Start with the E-2 eligibility and application overview
Fifty percent is a line about the enterprise, and a management agreement does not move it
The enterprise itself must be at least fifty percent owned by nationals of the treaty country, and ownership is traced through to the individuals who ultimately hold it rather than stopping at a corporate name. With the founder retaining fifty-five percent as a United States citizen, treaty-national ownership stands at forty-five, and the enterprise does not qualify no matter how the management agreement reads. Control is a separate and later question, asked of the investor rather than of the company: the investor must be in a position to develop and direct the enterprise, which ordinarily means at least half the ownership or demonstrable operational control through some other mechanism. Answering the second question well cannot repair a failure on the first, and the deal has to be restructured rather than re-described.
Irrevocably committed and at risk means the money has already gone
Capital counts when it has been placed at risk in the commercial sense, subject to partial or total loss if the business fails, and irrevocably committed to the enterprise. A balance in an account earmarked for a purchase is neither. Funds released to the seller, equipment purchased, a lease executed and signed for, licences paid, inventory acquired and staff hired are all evidence of commitment. Escrow arrangements are used routinely and have to be drafted carefully, because money returnable at the buyer's discretion has not been committed at all. Borrowed capital may qualify where the loan is secured against the investor's personal assets rather than against the assets of the business being purchased, since a loan secured by the enterprise itself puts the lender's money at risk instead of the investor's.
Substantial and non-marginal are separate findings with separate evidence
Substantiality is proportional rather than absolute. There is no published minimum, and the amount is weighed against the total cost of purchasing an established business or of establishing a viable new one, with a proportionately higher share expected of a lower-cost enterprise. A calibration laboratory with modest fixed assets therefore invites a high percentage rather than a large number. Marginality is a different question about the future: the enterprise must have the present or future capacity to generate more than a minimal living for the investor and family. Historical financial statements answer part of it, and where they do not, a plan showing capacity to expand within roughly five years is the accepted route. The enterprise must also be real and operating, not idle, speculative or a paper holding of assets.
There is no direct path from this route to permanent residence
Treaty investor status can be maintained for as long as the qualifying investment and activity continue, and periods of admission are renewable, but the category leads nowhere by itself. It creates no queue, accrues no priority date and confers no right to remain if the business is sold or the ownership ceases to be majority treaty-national. That matters for planning around children, because a derivative child stops qualifying at twenty-one and a family that has been present for years may find its eldest without status while the parents' position is unchanged. A spouse in the category is employment authorized incident to status and may work for any employer. Where permanent residence is the actual objective, it must be pursued through a separate route and started deliberately rather than assumed to follow.
