H1B Sponsorship Explained: Everything You Need to Know in 2026

What is H1B Sponsorship?

H1B sponsorship is when a US employer files an H1B petition with US Citizenship and Immigration Services (USCIS) to employ a foreign national in a specialty occupation — any role typically requiring a US bachelor's degree or equivalent in a specific field.

The word "sponsorship" can be misleading. The employer is not financially sponsoring your immigration in the way a family might sponsor a relative. They are acting as the petitioner — filing paperwork, paying fees, and taking on legal obligations to the Department of Labor regarding your wages and working conditions.

Without an employer willing to sponsor you, you cannot obtain an H1B visa — there is no self-petition option for H1B (unlike the EB-2 NIW green card, which allows self-petition).

What the Employer Is Required to Do

When a company sponsors your H1B, they are legally required to:

Pay at least the prevailing wage for your role, experience level, and location as set by the DOL

File an LCA (Labor Condition Application) with the DOL before petitioning USCIS

Post a notice of the LCA at the worksite for 10 business days

Pay the required USCIS filing fees (unless exempt)

Maintain your status and notify USCIS if your employment ends

Pay return transportation costs if you are dismissed before your H1B expires

The LCA and Prevailing Wage

Before filing your H1B petition, your employer must obtain a certified Labor Condition Application (LCA) from the Department of Labor. The LCA is a public document — every certified LCA is published in the DOL's disclosure database, which is the source of the H1B data you see on JobOS's company pages.

The LCA requires the employer to attest to paying you at least the prevailing wage — the DOL's determination of what workers in similar roles earn in your area. Wages are set at four levels:

Level IEntry-levelLimited experience, supervised work

Level IIQualifiedSome experience, basic judgment required

Level IIIExperiencedFull use of knowledge and skills

Level IVFully competentComplex tasks, independent judgment

This is why H1B sponsorship can actually work in your favor during salary negotiation — the prevailing wage sets a legal floor, and employers who routinely sponsor H1B workers are often willing to discuss compensation more transparently. See our salary negotiation guide for how to use this.

The H1B Lottery and Timeline

January–FebruaryPrepare. Get your employer to agree to sponsor. Compile all documents.

March 1–18Registration window. Employer submits your basic info to USCIS for $215.

Late MarchLottery selection. USCIS randomly selects ~28% of registrations.

AprilSelected registrants are notified. Full petition filing begins.

June–SeptemberUSCIS adjudicates petitions. Standard: 3–5 months. Premium: 15 days.

Lottery odds in 2025: Approximately 28% selection rate. If not selected, you stay on OPT (or other status) and can try again next year. The H1B lottery has become increasingly competitive — see our backup strategies guide.

Cap-Exempt vs Cap-Subject Employers

Not all employers are subject to the 85,000 annual H1B cap. Cap-exempt employers can file H1B petitions year-round with no lottery:

Institutions of higher education — e.g., MIT, Stanford, state universities, community colleges

Nonprofit affiliates of universities — e.g., Teaching hospitals, university-affiliated research labs

Nonprofit research organizations — e.g., RAND, Brookings, many think tanks

Government research organizations — e.g., NIH, NASA, national labs (Argonne, NREL)

Working for a cap-exempt employer first is a common strategy — you get H1B status without competing in the lottery, then transfer to a private company later. See our full cap-exempt employer list.

How to Find H1B Sponsors

The most reliable way is to cross-reference the DOL's public LCA disclosure data — the same USCIS database that powers JobOS's H1B company database. Every company that has filed an H1B petition in the last 10 years appears in this database with filing counts, wage levels, and job categories.

On JobOS, when you search for jobs, every listing is automatically cross-referenced against this database. Companies with ✅ "Confirmed H1B" badges have verified filing history. Use the H1B filter to see only these employers in your search results.

H1B Portability and Changing Jobs

Under AC21 portability, you can change employers after your H1B has been approved (or pending for 180+ days). The new employer files an H1B transfer petition, and you can begin working as soon as it is filed — before it is approved. This protects you from gaps in employment status.

There is no cap on H1B transfers — once you have H1B status, you can change employers as many times as you like without re-entering the lottery. The key is continuity: always have a new H1B transfer petition filed before leaving your current employer.

Frequently Asked Questions

What does it mean for a company to sponsor an H1B?▼

H1B sponsorship means an employer files an H1B petition with USCIS on behalf of a foreign national employee. The employer is not "giving" you anything — they are certifying that they need your skills, paying required government fees ($1,710–$6,460+), and attesting to pay you at least the prevailing wage for your role and location as determined by the Department of Labor.

Does H1B sponsorship cost the employee anything?▼

Legally, the required USCIS filing fees must be paid by the employer, not the employee. However, the employee can pay for premium processing ($2,805 to expedite within 15 days) if desired. Some employers offer to cover this as a benefit. It is illegal under DOL regulations for employers to pass the basic H1B petition cost to the employee.

How long does H1B sponsorship take?▼

The standard timeline runs: October 1 (earliest start date) → April registration window → May lottery selection → June-September USCIS adjudication → October 1 start date. Total: up to 12 months from registration. With premium processing, adjudication is reduced to 15 business days after USCIS receipt. Cap-exempt employers (universities, nonprofits) can file year-round with no lottery wait.

What is the difference between H1B cap-subject and cap-exempt?▼

Cap-subject employers (most companies) must compete in the annual H1B lottery capped at 85,000 new visas per year (65,000 regular + 20,000 for US master's degree holders). Cap-exempt employers — including accredited universities, nonprofit research organizations, and government research institutions — can file H1B petitions at any time without competing in the lottery, making them significantly more accessible for international workers.

Can I change employers on H1B?▼

Yes. H1B is employer-specific but portable. Under the AC21 portability provisions, if you've been on H1B for 180+ days and a new employer files an H1B transfer petition, you can start working for the new employer as soon as the transfer petition is filed (not when it's approved). The new employer bears the full cost of the transfer filing.

What happens if I get laid off on H1B?▼

H1B holders have a 60-day grace period after job loss to find a new employer and file a transfer petition, change to a different visa status, or depart the US. You cannot work during this grace period. File a new H1B transfer petition or change your status before the 60 days expire to maintain legal status.
