Read the general life across the border overview
Hypothetical example: a Champlain couple hold E-2 status through the wife's investment in a U.S. business; the husband works incident to his derivative status, and their son, now nineteen, is starting college in the United States. On his twenty-first birthday the son loses derivative eligibility whatever his parents' status, so the family's planning question is not whether but when and how he changes to a status of his own. Each person's rights are separate: the investor's, the working spouse's and the student's.
The son: change status before the birthday, not after
A derivative child in E-2 status may study, may not work, and ceases to qualify as a derivative at twenty-one. The usual answer for a student is a change to F-1 status, which requires admission to a school certified by the Student and Exchange Visitor Program, a Form I-20, proof of funds and an application filed while he is still in valid derivative status and with enough lead time for adjudication. Filing close to the birthday risks a gap. If he intends to work after graduation rather than study, no status follows from his parents, and the family should look at whether his own qualifications and a U.S. employer could support a category of his own, remembering that as a Canadian citizen he could later use TN if his profession is listed.
The husband: broad work rights that end when hers do
The spouse of an E-2 investor is employment-authorized incident to status and may work for any employer or himself without a separate permit. That authorization is derivative: it lasts while the investor's E-2 status and his own remain valid, and it ends if the business ceases to qualify, if the investor's admission period lapses or if the marriage ends. Separation alone does not automatically terminate derivative status while the marriage legally continues. He should keep his admission record current for employers and should note that E-2 admissions are granted in periods that must be renewed, so the family calendar should show each person's expiry, not only the investor's. His Canadian or other nationality is not tested; only the investor and the enterprise's ownership must be treaty nationals.
The investor: keep the enterprise qualifying, because everyone depends on it
The family's status rests on the business continuing to meet the E-2 conditions: real, operating, more than marginal, at least half treaty-owned, and directed by the investor. A sale of the business, a dilution of ownership below half, or a period of dormancy affects all three family members at once. Keep the corporate records, tax returns and payroll in order for each renewal, and plan any change of ownership with the family's status in mind. Because E-2 offers no direct path to permanent residence, a family that intends to remain permanently should consider, well before the son's birthday, whether an employment-based or investment-based immigrant route is available and how the son's age would be treated under it.
