Business Immigration Attorney: Employer and Investor Overview
Business immigration covers every lawful route a company or investor uses to bring talent and capital into the United States: work visas, treaty visas, employer-sponsored green cards and the compliance that holds them together. Capitol Law Partners advises startups, employers, multinational groups and investors on which category fits, in what order, and how to keep the record clean through to permanent residence. Family and humanitarian matters sit in our broader immigration law practice.

A guide for employers
Hiring a foreign professional for the first time
Start with the candidate's status and the job. A graduate on F-1 OPT, a transfer from a foreign office and a Canadian engineer each point to a different category with different costs, timing and attestations. We recommend a primary route and a fallback before filing.
Cap season planning
Cap-subject H-1B registrations are submitted in March for an October start, so candidates must be identified early and bridged if not selected. We prepare alternatives such as O-1A, TN or L-1 so a lottery result does not stop a hire.
Transfers and extensions
A new employer, a new metropolitan area, materially different duties or an extension each requires a filing. We track the dates and changes so no one works outside an approved petition.
Compliance: LCA public access files and Form I-9
H-1B and E-3 employers must keep a public access file for every Labor Condition Application, with the certified LCA, the wage rate and its basis, the posting notices and a benefits summary, retained after the LCA ends. Every employer must also complete Form I-9 for each new hire within three business days of the start date and reverify expiring work authorization. We set up and audit both.
When an employee leaves
A bona fide termination of an H-1B worker requires written notice to the worker, notice to USCIS to withdraw the petition, and an offer to pay reasonable return transportation; until then, the LCA wage obligation can continue. The worker generally has up to 60 days to find a new sponsor, change status or depart.
A guide for founders and investors
The visa follows the stage of the business. A treaty-country founder funding a new U.S. company usually begins with the E-2, which has no fixed minimum investment and is renewable while the business qualifies. An established foreign company opening a U.S. subsidiary transfers its leadership on the L-1A. A founder with a strong record may qualify for the O-1A or an EB-2 National Interest Waiver. Investors seeking permanent residence directly consider the EB-5; executives who have run the U.S. company for a year move to the EB-1C. Our business and corporate law team handles the entity, operating agreements and contracts behind the visa.
Turkish companies and investors
Turkey maintains a treaty of commerce and navigation with the United States, so Turkish nationals qualify for the E-2 and E-1 visas, and Turkish companies opening U.S. offices use the L-1A and later the EB-1C. Our Istanbul office works with founders on business plans, source-of-funds documentation and interview preparation; our U.S. offices handle formation and USCIS filings.
2025 fee and policy changes
New fees, entry restrictions and selection rules affecting several employment categories were announced in 2025, and their scope remains subject to agency guidance and litigation. We confirm the rules that apply to your filing at consultation.
Process overview and what to bring
- Strategy consultation. We review the company, the role or investment and the person's status, then recommend a route, timeline and alternatives.
- Document collection. Employers bring the job description, organizational chart, formation documents, financials and the candidate's credentials and immigration history; investors bring proof of nationality, ownership documents, bank records tracing the funds and a business plan.
- Government filings. Department of Labor steps where required, then the petition with USCIS or the application at a consulate.
- Decision and follow-up. RFE responses, interview preparation, compliance files and a calendar for what comes next.
