U.S. Work Visa Sponsorship: H-1B, H-2B, L-1, O-1 and TN Explained

You've seen the posts: "U.S. employers sponsoring now". Some are real opportunities. Many are recycled, exaggerated or outright scams. The only way to tell the difference is to understand how sponsorship actually works.

This guide explains the main temporary U.S. work visas, what each one needs from you and from the employer, what it costs and how long you can stay. If you're looking for a permanent green card through work instead, see our guide to EB visas.

What sponsorship actually means

In U.S. immigration, the employer is the petitioner and you are the beneficiary. "Sponsorship" means the employer applies on your behalf, usually on Form I-129, Petition for a Nonimmigrant Worker.

Before that, many categories need a step at the Department of Labor (DOL):

• A Labor Condition Application (LCA) for the H-1B, where the employer attests to wages and working conditions.
• A temporary labor certification for the H-2A and H-2B, where DOL checks that U.S. workers aren't available and wages won't be undercut.

Sponsorship is not approval. USCIS decides the petition, then a U.S. embassy or consulate decides your visa, then a border officer decides whether to admit you. Each can say no.

The main sponsored work visas at a glance

H-1B: specialty occupations

The H-1B is for jobs that need highly specialised knowledge and at least a bachelor's degree in a directly related field, or its equivalent. You can also qualify with an unrestricted state licence for the job, or with experience that counts as equivalent to a degree.

The cap and the lottery

Congress caps new H-1B visas at 65,000 a year, plus 20,000 for people with a U.S. master's degree or higher. Some jobs are exempt from the cap, including roles at U.S. institutions of higher education and certain related organizations.

For cap-subject jobs, the employer must first register you online and pay a $215 registration fee. If there are more registrations than visas, USCIS now runs a weighted selection based mainly on the wage level of the job. Higher-paid offers get better odds.

USCIS says it has already received enough petitions to reach both caps for fiscal year 2027. Watch the USCIS H-1B cap season page for the next registration dates.

The $100,000 payment

A presidential proclamation from September 2025 added a $100,000 payment for certain new H-1B petitions, mainly for workers outside the U.S. without a valid H-1B visa.

That payment is now in litigation. USCIS says a federal court vacated its implementing guidance on 8 June 2026, and on 24 July 2026 the appeals court declined to pause that order. DHS says it is complying for now but plans to collect the payment if the order is lifted. Check the USCIS H-1B page before any decisions.

H-2A and H-2B: seasonal and temporary work

H-2A: temporary farm work

The H-2A lets U.S. farm employers hire foreign workers for temporary or seasonal agricultural jobs. The employer must first get a temporary labor certification from DOL, then file with USCIS.

You don't need a degree. Status can be extended in steps of up to 1 year, and USCIS sets a maximum period of stay of 3 years. The job is tied to the employer and the season.

H-2B: temporary non-farm work

The H-2B covers seasonal, peak-load, intermittent or one-time non-agricultural needs. Think resorts, landscaping, seafood processing and similar work.

Congress caps the H-2B at 66,000 a year: 33,000 for jobs starting between 1 October and 31 March, and 33,000 for jobs starting between 1 April and 30 September. Demand is high, so employers file early.

DOL says the employer must offer at least the highest of the prevailing wage and the applicable federal, state or local minimum wage. As with the H-2A, the maximum stay is 3 years. After reaching it, USCIS says you must stay outside the U.S. for at least 60 uninterrupted days before returning in H-2B status.

L-1: transfer within your company

The L-1 lets a multinational company move staff to a related U.S. office, such as a parent, branch, subsidiary or affiliate.

For the L-1A (managers and executives), you generally need one continuous year of work for the company abroad within the 3 years before your admission. The L-1B is a separate category for employees with specialised company knowledge.

USCIS allows an initial stay of up to 3 years, or 1 year if you're opening a new U.S. office. L-1A extensions come in steps of up to 2 years, to a maximum of 7 years. Your spouse and unmarried children under 21 can come with you in L-2 status.

The practical lesson is simple. If you want an L-1 later, you need to be working for an international company now.

O-1 and TN: talent and trade-agreement visas

O-1: extraordinary ability

The O-1 is for people at the top of their field:

• O-1A for the sciences, education, business or athletics
• O-1B for the arts, film and television

USCIS describes O-1A extraordinary ability as being among the small percentage who have risen to the very top of the field. The employer or agent must also include a written advisory opinion from a peer group or expert. The initial stay is up to 3 years.

Evidence usually means major awards, press coverage, high pay, judging others' work or critical roles in well-known organizations. This isn't a route for most job seekers, but it's worth knowing if your record is strong.

TN: Canadian and Mexican professionals

The TN comes from the U.S.-Mexico-Canada Agreement (USMCA). It is only for citizens of Canada or Mexico working in a profession included in the agreement's list, in a prearranged full-time or part-time job.

Canadians can often apply directly at a designated port of entry with an employer letter. Mexicans must get a TN visa from a U.S. embassy or consulate first. The initial stay is up to 3 years and can be extended.

How the sponsorship process works, step by step

1. You get a genuine job offer from a U.S. employer that is willing to sponsor.
2. The employer checks the category. It confirms the job and your background fit a specific visa.
3. DOL step. The employer files an LCA (H-1B) or temporary labor certification (H-2A, H-2B), where required.
4. H-1B registration, if the job is cap-subject, and selection.
5. The employer files Form I-129 with USCIS, with any premium processing request.
6. You apply for the visa at a U.S. embassy or consulate, including the online DS-160 form and an interview if required. Canadian TN applicants can skip this step.
7. You're inspected at the border and admitted for the approved period.
8. You maintain status by working only for your sponsor, in the approved role, and filing extensions on time.

What it costs, and who pays

The figures below come from the USCIS fee schedule, Form G-1055, edition dated 9 September 2026. Most are employer costs.

Small employers and nonprofits pay reduced base fees in several categories, and some have extra fees in specific cases. Always use the current fee schedule, not this table, when budgeting.

Your own costs usually include a passport, the State Department visa application fee, medical or police documents if asked, and travel. Once you arrive, budget for a deposit on housing, health insurance if your employer doesn't provide it, and opening a U.S. bank account, which usually needs your passport and proof of address. If you send money home, compare transfer fees and exchange rates, as they vary a lot between providers.

From a work visa to a green card

A temporary visa is not permanent residence. But some categories can lead there.

H-1B and L-1 workers are often sponsored later for an employment-based green card, usually through EB-2 or EB-3, or EB-1 for multinational managers. O-1 holders sometimes move into EB-1 or the EB-2 National Interest Waiver.

H-2A, H-2B and TN are built around temporary jobs and the intent to return home. Plan with that in mind. If you work in care, construction, hospitality or manufacturing and want a permanent route, read our EB-3 guide for caregivers and skilled workers.

Finding genuine sponsors and avoiding scams

How to find genuine sponsors

• Target employers who already hire international staff, such as hospitals, universities, large tech and engineering firms and established seasonal employers.
• Apply on the employer's own careers page and confirm the job exists there.
• Match the visa to the job. A cleaning job can't be an H-1B. A software role won't be an H-2B.
• Ask direct questions: Which visa? Who files? Which DOL filing is needed? What is the wage and location?
• Check the company exists through its website, state business registration and independent reviews.

Scams to avoid

A real employer can tell you the company name, job title, location, pay, visa category and who is filing. If you get vague answers, stop.

Your next steps

1. Pick the one or two visas that realistically match your education, job and nationality.
2. Update your CV to show dates, duties and results clearly, in a U.S. format.
3. Gather evidence: degree certificates, transcripts, employer reference letters and licences.
4. Get a credential evaluation if you're aiming for an H-1B with a foreign degree.
5. Apply only to verifiable employers and never pay for a job offer.
6. Check the latest USCIS page for your visa before you accept an offer, especially for H-1B fees.
7. Compare permanent routes too, using our guide to all the ways to get a U.S. green card.
