What Corporate Immigration Services Do U.S. Employers Need?

Corporate immigration is a business function, not a personal one. The employer files most petitions and carries most of the legal risk. Companies rarely call counsel for a single form; they call when a new hire needs work authorization, when a foreign parent wants to move staff into a U.S. .ffice, or when a current employee's status is about to expire.

The work reaches well beyond filing a visa petition. A full business immigration practice also handles PERM labor certification, consular processing at posts abroad, adjustment of status inside the country, responses to a Request for Evidence, green card sponsorship, I-9 audits, and naturalization questions for long-tenured staff. Four federal agencies share this process, and knowing which one controls a given step prevents costly missteps:

• USCIS adjudicates petitions and applications filed inside the United States
• The Department of Labor reviews Labor Condition Applications and PERM labor certifications
• The Department of State issues visas at U.S. .onsulates abroad
• Customs and Border Protection inspects travelers and grants admission at ports of entry

Sponsorship programs differ in who qualifies, how long approval takes, and what the employer must prove. The programs below cover most corporate filings, and many employers combine them by starting a worker on a temporary visa and later filing for permanent residence.

The H-1B applies to positions that normally require at least a bachelor's degree in a specific field. Before filing, the employer submits a Labor Condition Application to the Department of Labor and agrees to pay the required prevailing wage. Congress caps most new H-1B numbers each fiscal year, so employers who plan around the registration window keep more flexibility than those who wait. The L-1 lets a company move a manager, executive, or specialized-knowledge employee from a qualifying foreign office to a related U.S. .ntity, and it has no annual lottery.

Three narrower options fill common gaps. The O-1 fits a worker with extraordinary ability in science, business, the arts, or athletics. The TN serves Canadian and Mexican professionals in occupations listed under the USMCA. The E-2 supports a national of a treaty country who directs a business built on a substantial investment. For a permanent hire, the EB-3 category leads to a green card and, in most cases, requires PERM labor certification that tests the local labor market first. Because permanent sponsorship runs longer than a temporary visa, employers often begin it well before they need the worker to stay, and broader employment-based immigration planning ties these routes together.

Sponsoring a worker is only half the job. Federal law also holds employers responsible for verifying eligibility, documenting wages, and surviving an audit. Sound immigration compliance records are the first thing government reviewers ask to see.

The Immigration Reform and Control Act requires every U.S. .mployer to complete Form I-9 for each new hire and to confirm identity and work authorization. Employers must keep each Form I-9 for three years after the hire date or one year after employment ends, whichever is later. E-Verify, the federal online check, is voluntary nationwide but mandatory for many federal contractors and for private employers in several states. New York does not require most private employers to use E-Verify, so a New York company should confirm which rule applies before it builds a hiring process around the tool.

H-1B sponsorship adds its own paperwork. After filing the Labor Condition Application, the employer must assemble a Public Access File, generally within one working day, and keep it available for public inspection. That file holds the certified LCA, the wage rate, the basis for the prevailing wage, and proof that the employer notified affected workers. Missing or late records are a frequent audit finding, so employers should build the file when the LCA is filed rather than reconstruct it later.

Payroll adds a further layer. Sponsored employees are generally subject to federal income tax withholding and, in most cases, Social Security and Medicare contributions, though a tax treaty can change the result. For a worker based in New York, state income tax withholding applies alongside the federal rules. On enforcement, Immigration and Customs Enforcement can open an I-9 audit with a Notice of Inspection, and penalties rise for repeat or willful violations, with criminal exposure in serious cases.

Immigration works best as part of workforce strategy, not a last-minute reaction. Companies that map their hiring calendar against visa timelines avoid the scramble that comes with cap deadlines and long green card queues. Planning also clarifies which roles justify permanent sponsorship and which fit a temporary visa.

Each program carries its own government fees, legal work, and processing window. Temporary visas generally move faster than permanent sponsorship, though premium processing can shorten some USCIS timelines for an added fee. Counsel manages each petition from evidence gathering through filing deadlines, keeps I-9 and wage records ready for review, and flags how new regulations affect current employees and future hires.

How long does it take to sponsor an employee for a work visa or green card?

Timelines vary by program. A cap-subject H-1B can run several months from the spring registration to an October start date, while premium processing can cut the USCIS decision to about two to three weeks for an extra fee. Permanent residence through PERM and the EB-3 category often takes a year or more, and applicants from countries with heavy demand can wait considerably longer because of annual per-country limits. Starting early is the single biggest factor an employer controls.

Who pays the fees for employment-based visa sponsorship, the employer or the worker?

Federal rules place several costs on the employer. For an H-1B, the employer must pay the training and fraud-prevention fees and cannot shift Labor Condition Application costs to the worker if doing so drops pay below the required wage. Costs tied to PERM labor certification also fall on the employer. Optional premium processing can be paid by either side, and a written fee agreement keeps expectations clear before filing.

The right approach depends on the role, the timeline, and whether you plan to keep the worker permanently. Our team reviews your workforce needs, identifies the visa and compliance steps that fit each hire, and outlines the fees and timelines before you commit.
