A case-by-case option for founders whose background and intended US work may support an O-1A petition; nationality alone does not determine eligibility.
Potentially relevant signals include sustained recognition in the founder’s field and a well-documented plan for the founder’s intended US work. Meeting individual signals does not establish eligibility; the petition must be evaluated as a whole under current requirements.
Evidence may include independently verifiable awards or recognition, published coverage, judging, original contributions, leading or critical roles, compensation, expert letters, and business or role documentation. Quality, independence, and context matter; these themes are not a guaranteed checklist.
Planning should treat evidence review, petition preparation, USCIS adjudication, and—where applicable—consular processing or change of status as separate stages. Duration varies by case, filing service, and post, so any planning range is an estimate and no approval date should be promised.
Company ownership, a genuine US role, the petitioner or employer structure, and work authorization should be reviewed together by counsel. Forming an LLC or C-Corp by itself does not create an O-1A pathway or authorize work in the United States.
A case-by-case pathway for founders expanding a qualifying business from UK to the United States; the qualifying company relationship and employment history matter, not nationality alone.
The founder-facing route is generally L-1A for an executive or manager. L-1B may be relevant when specialized knowledge is the applicable classification. The beneficiary normally needs at least one continuous year of qualifying employment abroad for the related organization within the applicable lookback period. Meeting one fact alone does not establish eligibility; the petition must be assessed as a whole under current requirements.
The foreign and US entities must have a qualifying relationship—parent, subsidiary, affiliate, or branch—and active business operations in UK and the United States. Evidence should support the beneficiary’s qualifying foreign role and a genuine US executive, managerial, or specialized-knowledge role. Owning or forming a US LLC or C-Corp alone does not establish an L-1 relationship or work authorization; founder-owned companies also need an ownership/control review. A new-office case may require evidence of the proposed US organization, premises, funding, and ability to support the role.
Document the foreign company and qualifying relationship; form or expand the US entity; prepare the organization chart, business plan, office, and financial evidence as applicable; and have the US petitioner file Form I-129 with the L classification supplement. Complete premium processing, change-of-status, or consular-processing steps only when applicable. Preparation and adjudication timelines vary by case and filing path, so all timelines are estimates and approval is not promised.
Government petition: plan for about $1,385 for a regular Form I-129 L filing or about $695 for a small employer/nonprofit filing, before applicable additions. Additional fees: an initial L petition may include a $500 fraud-prevention fee and an asylum-program fee of about $600 ($300 for a small employer; $0 for a nonprofit); a $4,500 large-employer fee may apply in qualifying cases. Optional premium processing: about $2,805. Attorney fees: often several thousand dollars or more depending on complexity. US entity/new-office setup: state filing, registered agent, premises, staffing, and operating costs vary widely. These are planning estimates; USCIS fees can change and may depend on petitioner size/status. Verify current USCIS fees before filing.
For founders from UK, E-2 eligibility is case-specific and depends on current agency and consular rules, treaty-country nationality facts, the enterprise, and the investment. For UK nationals, the treaty applies only to British territory in Europe (the British Isles except the Republic of Ireland, the Channel Islands, and Gibraltar) and to inhabitants domiciled there; confirm nationality, residence, and domicile facts. Confirm the current Department of State treaty-country list, E-2 visa overview, and applicable USCIS requirements before relying on this pathway.
The founder generally needs treaty-country nationality, and the US enterprise must be at least 50% owned by nationals of a treaty country. The investment must be substantial relative to the total cost of the enterprise, with lawfully acquired funds committed and placed at commercial risk. The business must be real, active, and operating, and must be more than marginal; the founder must be able and intend to develop and direct it. These are general signals, not a determination that any UK founder qualifies.
There is no universal minimum-dollar threshold for E-2 eligibility. Review whether the investment is proportional to the business’s total cost, whether the source and traceability of funds can be documented, and whether the ownership or operational control supports the founder’s role. Business-plan, operating, and financial evidence matter; passive ownership alone is not the same as E-2 management. Invested business capital is separate from filing and preparation costs.
Confirm treaty nationality and enterprise ownership; choose consular processing abroad or, if eligible and already in the United States, a USCIS change-of-status or extension petition; document the source and path of invested funds; prepare the business plan and operating, ownership, and financial evidence; then follow the consulate’s E-visa instructions, complete Form DS-160, and attend any required interview, or file the applicable Form I-129 petition. Have a qualified immigration attorney review the route and evidence before filing.
Consular visa application: $315 per applicant for an E visa (Department of State fee, as of September 2026; nonrefundable); verify it on the Department of State visa fee page. A nationality-dependent visa issuance fee may also apply; check the State Department reciprocity table. In-country USCIS petition: if requesting a change or extension of status with Form I-129, the E-category filing fee is $1,015 for a regular petitioner or $510 for a small employer or nonprofit, plus any applicable additional fees (as of September 2026); check the USCIS fee schedule. Optional legal and business-plan preparation: variable; request quotes. These filing and preparation costs are separate from the invested business capital, which has no universal minimum-dollar threshold.
