1. U.S. Work Visa | U.S. Nonimmigrant and Immigrant Work Visas
The U.S. work visa is broadly divided into immigrant visas (permanent residence) and nonimmigrant visas (temporary employment).
A nonimmigrant work visa is a status that allows the applicant to reside and work in the United States temporarily for purposes such as a specific employment contract or project, academic or research work, or cultural activities.
An employment-based immigrant visa is a status that allows a person to obtain permanent residence and reside and work in the United States indefinitely.
A nonimmigrant work visa is largely temporary in nature, and it requires immigration approval each time the employment contract is extended or changed.
By contrast, when an immigrant visa is granted, the recipient is granted permanent residence upon approval, which provides greater freedom in choosing employment and greater stability of stay.
Both systems require review and approval by relevant agencies such as U.S. Citizenship and Immigration Services (USCIS), the Department of State (DOS), and the Department of Labor (DOL), and each stage of the U.S. work visa application calls for strict requirements and careful document preparation.

3. U.S. Work Visa | Overview of Employment-Based Immigration (Permanent Residence)
While a nonimmigrant work visa allows only a limited period of stay, employment-based immigration is a system that grants a Green Card (permanent residence) in the United States.
Among U.S. work visas, immigrant visas are broadly classified from EB1 to EB5.
Outstanding scientists, professors, researchers, and executives of multinational companies are exempt from the PERM (Program Electronic Review Management) labor certification process.
If their qualifications are demonstrated, they may file the I-140 directly.
This is an immigrant visa for which those holding a master's degree or higher, or those with equivalent experience and ability, may apply.
Those holding advanced degrees such as a master's or doctorate, and those with exceptional ability in business, science, the arts, and similar fields, may omit labor certification through the National Interest Waiver (NIW).
Skilled workers with at least a bachelor's degree, or unskilled workers with two years or less of experience, may apply for the U.S. work visa corresponding to EB-3.
In other words, it is permanent residence provided to general laborers and their families, and its scope of eligibility is very broad.
However, in this case the processing period can take several years.
This is a visa for religious workers, employees of international organizations, interpreters for the U.S. military overseas, and others.
It applies to those who have been granted the opportunity to immigrate by the U.S. government for political or moral reasons, and special statutes apply by occupation.
A person who invests capital of at least 1.05 million dollars (800,000 dollars in a targeted employment area) in a U.S. business and creates at least 10 full-time jobs becomes eligible to apply for the EB-5 immigrant visa.

4. U.S. Work Visa | Common Application Procedure and Requirements
For most nonimmigrant work visas, such as H, L, O, P, and R, the U.S. employer or official agent must first file the I-129 petition with U.S. Citizenship and Immigration Services to apply for labor certification.
After the petition is approved, the applicant completes the DS-160 visa application and then attends the embassy interview.
[U.S. Work Visa Application Procedure]
The employer files the I-129 petition → U.S. Citizenship and Immigration Services approves the petition → the petitioner completes the online visa application DS-160 → the embassy interview → the visa is issued
If you need to obtain a U.S. work visa quickly, you may apply for expedited review through the immigration service's premium processing service.
The applicant must meet the requirements in the relevant field, such as education, experience, and award records, and the employer must also be able to demonstrate the employment contract, the planned activities after the worker is hired, and the company's financial condition.
Because the items required differ for each visa, careful preparation of materials for the U.S. work visa application is required in order to anticipate the RFE (Request for Evidence) that review agencies often issue.
5. U.S. Work Visa | Key Points to Note When Obtaining One
The review authorities do not recognize eligibility based on documents alone.
They comprehensively evaluate the applicant's achievements, employment contract, wage conditions, and similar factors.
In particular, the H-1B requires that minimum wage conditions be met through the Department of Labor's LCA (Labor Condition Application), and the L-1 requires proof of a genuine relationship between the headquarters and the branch.
In addition, a U.S. work visa permits activity only within the scope of the approved duties, employer, and working conditions.
To transfer to another company or change duties, a new petition must be filed, and it should be noted that an unauthorized change may be regarded as unlawful presence.
Sponsor Requirements
If the employer is a shell company, the petition is likely to be denied.
It must be demonstrated that the company is actually operating and has sufficient ability to pay wages, and the submission of false materials is regarded as immigration fraud and may result in criminal punishment.
In addition, RFEs frequently arise from unclear eligibility, an incomplete employment contract, insufficient proof of experience, and similar issues.
Expert advisory letters, letters of recommendation, press coverage, and the effectiveness of the employment contract must be carefully reinforced.
A work visa permits activity only within the scope of the approved duties, employer, and working conditions. To transfer to another company or change duties, a new petition must be filed, and an unauthorized change may be regarded as unlawful presence.
6. U.S. Work Visa | Stay, Extension, and Change of Nonimmigrant Work Visas
For the U.S. work visa, the initial authorized period and the available scope of extension differ for each visa.
An extension application must be made before expiration, and remaining unlawfully after the status has expired becomes grounds for removal.
However, because some visas allow conversion from a nonimmigrant work visa to an immigrant visa (permanent residence), if you hold a professional visa or an extraordinary ability visa, it is advisable to keep in mind a later upgrade to an immigrant visa such as EB-1 or EB-2 and to prepare for the process in advance.
Monitoring of Approval Requirements and Review Standards by Visa
The U.S. nonimmigrant work visa is an important system that enables talent from around the world to move into the United States.
However, the approval requirements and review standards for each visa continuously change, and because the procedures are complex and the documentary requirements are extensive, formally meeting the eligibility requirements does not result in automatic approval.
The applicant must carefully select the visa type that suits their background and project, and must prepare the supporting materials strategically through prompt communication with the employer and agent and collaboration with an immigration attorney.
In particular, professional assistance from the petition-drafting stage through embassy interview preparation, RFE responses, and re-application strategy after a denial is a key factor that can improve the likelihood of approval.
During the change, extension, and stay-management process as well, compliance with U.S. local regulations is necessary, and if the eligibility requirements change, the change must be reported to U.S. Citizenship and Immigration Services immediately in order to avoid disadvantages.
The firm assists with the process, with a foreign attorney advising on U.S. law (United States) and immigration attorneys who have handled numerous immigration cases responding together to U.S. work visa matters.
