U.S. Market Entry Services for Companies
Dedicated Service for U.S.-Bound Companies
U.S. market entry and employee assignments — from visa strategy to ongoing management
Centered on B-1/B-2, E-2 Employee and L-1 visas, we review corporate structure, the U.S. entity, assigned employees, interviews and tax issues together, and manage cases for multiple employees systematically.
Which U.S. visa fits your company?
The visa to review and how to prepare differ depending on your situation — short business trips, assigning employees to a U.S. entity, or transferring staff from the Korean headquarters.
3 Principles Behind Our Corporate Visa Work
We don't just pick a visa type — we treat your U.S. entry structure and the management of assigned staff as a single project.
Analyze the Structure First
We first review the relationship between the Korean headquarters and the U.S. entity, ownership, the purpose of the assignment and the role, then design a U.S. visa strategy that fits.
Manage at the Company Level
Even when several employees are in process at once, we manage individual cases together with the company-wide schedule and key issues requiring follow-up.
Connect Beyond the Visa
U.S. entity formation, tax and accounting, embassy interviews, renewals and follow-up are linked so the entry process continues without gaps.

STEP 5. Operate the U.S. Business
Even after obtaining visas, you'll need to continuously manage the company's actual business operations, hiring, accounting and tax filings, and the corporate records needed for visa extensions.
※ If You're Assigning Multiple Employees at Once
Large-scale U.S. investments or factory/facility projects may require assigning several employees to the U.S. at the same time. In these cases, it's important to manage the following at a company-wide level, not just on a case-by-case basis.
Shared corporate records for the U.S. entity and the Korean parent
Each assignee's position and duties
Assignment timing
The appropriate visa type for each employee
Interview schedules
Whether family members will accompany
Visa expiration and renewal schedules
Plans for additional future assignments
Having a standardized set of company records and a personnel-assignment management system can reduce repetitive paperwork and errors.
※ If You're Also Considering a Green Card Long-Term
If a company's key personnel will be working in the U.S. long-term, a long-term green card strategy can be considered in addition to nonimmigrant visa planning. Depending on the company's structure and the applicant's background, the following employment-based immigration categories may be considered.
EB-1C (Multinational Executive/Manager)
EB-1A
EB-2
NIW
EB-2 / EB-3 via PERM
Since nonimmigrant visas and green cards each have separate requirements, it's important to plan with long-term personnel strategy in mind from the early stages of U.S. entry.

FAQ
Which visas apply when sending employees to the U.S.?
Depending on the business purpose, the role, and the length of stay, the candidates are typically L-1, E-2 Employee, B-1/B-2, J-1, H-1B, and O-1. Each category has its own documents and procedure, and many of them presuppose a U.S. entity set up and operated in line with U.S. immigration law, so the strategy should be designed from the earliest stage.
Can multiple employee visas be filed at the same time?
Yes. Filing for many people at once does make scheduling, document standardisation, and error control harder. DaeYang has a dedicated process and experience in handling volume visa filings, so a company can run them together as one program.
Can I reapply after a visa refusal?
Yes. The reason for the refusal is analysed first, then supporting evidence is prepared to address that specific ground before refiling. Resubmitting the same package immediately after a refusal is the most common mistake.
Do you prepare applicants for the consular interview?
Yes. The consular interview is both essential and a frequent source of mistakes, so DaeYang’s U.S. attorney personally conducts interview coaching to raise the approval rate.
Can visa work be handled together with incorporation and tax matters?
Yes. Corporate clients are supported across U.S. non-immigrant visas (expatriate and employee assignments, small-scale investment, business visits), immigrant visas (EB-5, EB-1, NIW, EB-3EW, family sponsorship), and tax and accounting work (Korea-U.S. tax advice, international inheritance and gifts, U.S. incorporation, asset transfer and tax-efficiency planning).
How does DaeYang Immigration Law Group help companies entering the U.S.?
DaeYang supports corporate clients through a dedicated process: visa strategy built around the business purpose, category-specific expertise, volume visa handling, legal advice while cases are in progress, renewal and maintenance so expiry dates are never missed, and refusal analysis with a refiling strategy.
