What does 'must be authorized to work without sponsorship' mean for an F-1 student?

It excludes you. The phrase 'now or in the future' is the operative part: OPT is temporary work authorization, so a student on OPT will eventually need sponsorship. Posts with this wording are closed even though your OPT is currently valid.

Should I answer 'yes' to 'are you legally authorized to work in the United States?'

If you hold valid OPT, STEM OPT or H-1B status, yes. That question asks about current authorization, not permanent status. Answering 'no' because you are not a citizen or green card holder is a common mistake that screens people out unnecessarily.

Will I need sponsorship if I am currently on OPT?

Yes, and that is the honest answer on the application form. OPT and the STEM OPT extension both end, so continuing to work beyond them requires a change of status, normally to H-1B.

Why do some US jobs require a 'US Person' or citizenship?

Usually export-control rules (ITAR/EAR), security clearance eligibility, or a federal contract requirement. US law generally bars citizenship-status discrimination but carves out cases where a law, regulation or government contract requires it. An H-1B holder is not a US Person for export-control purposes.

Why do some job posts show a salary range and others do not?

Several US states and cities — including Colorado, California, New York State, Washington and Illinois — have pay transparency laws requiring a range in the posting. Whether one must appear depends on the job's location, so requirements differ by role and jurisdiction.

How can I tell whether an employer sponsors H-1B workers?

Check the Department of Labor's published LCA disclosure data, which names every employer with a certified labor condition application and the worksite. In the most recent quarterly file, 55,087 employers had certified H-1B LCAs across 9,178 US cities. A certified LCA is a filing step, not an approved visa.

Can I take a corp-to-corp or 1099 contract on an H-1B?

A 1099 arrangement is independent contracting rather than employment, and H-1B requires a petitioning employer and an employer-employee relationship. Corp-to-corp arrangements are common in IT staffing and are frequently not compatible with the status a candidate holds. Check the specific arrangement with an immigration attorney before accepting.

US Job Posts Explained: Sponsorship, Work Authorization & Pay

Q: Does the offered salary affect my H-1B chances?

It can. USCIS states that where selection is required, it conducts a weighted selection among registrations based generally on the highest OEWS wage level that the proffered wage equals or exceeds for the relevant occupation and area of intended employment.

One keyword decides most of your applications before you read a single responsibility. Here is which sentence to find first, which restrictions are federal law rather than employer policy, and how to check whether a company actually sponsors.

A US job post is written for an American reader. Almost every line in it that decides whether you can apply is written in a shorthand nobody explains — and most of it sits below the responsibilities, in the part people skim.

This is how to read one properly, and which sentences to find before you spend an hour on the application.

Find the work authorization line first

Before the role, before the salary, find this. It usually appears near the bottom under a heading like Additional Information, Requirements or Legal, and it comes in a small number of standard forms.

What the post says	What it means for you
"Must be authorized to work in the US without sponsorship, now or in the future"	Closed. This excludes anyone who will ever need an H-1B, including F-1 students on OPT, because OPT ends. Do not apply expecting an exception.
"We are unable to sponsor or take over sponsorship of an employment visa at this time"	Closed for now. "At this time" is usually boilerplate rather than a hint. Treat it as closed.
"Must be legally authorized to work in the United States"	Open. OPT and STEM OPT are legal work authorization. This phrasing does not exclude you.
"Visa sponsorship is available" / "We sponsor eligible candidates"	Open and explicit. Rare and worth prioritising.
Nothing at all about sponsorship	Unknown. Common. Apply, and expect the application form to ask.
"Must be a US citizen or green card holder" / "US Person"	Closed, and often legally required. See below — this one is usually not negotiable.

The two screening questions

Nearly every US application form asks a version of these, and people routinely answer them the wrong way round:

"Are you legally authorized to work in the United States?" If you are on F-1 with valid OPT, or on an H-1B, the answer is yes. Answering "no" here because you hold a visa rather than a green card is a common and costly mistake.
"Will you now or in the future require sponsorship for employment visa status?" If you are on OPT and will need an H-1B later, the answer is yes. OPT runs out.

Answer both honestly. These answers are checked again at offer stage against your I-9 documents and your I-94. A mismatch discovered then costs you the offer, and unauthorized employment has consequences well beyond the job — among other things, USCIS states that H-1B portability requires that you have not been employed without authorization since your last admission to the US. See our guide to H-1B portability.

"US Person" and clearance: the posts that genuinely cannot flex

Some restrictions are the employer's policy. Some are federal law, and no amount of enthusiasm moves them.

Export-controlled roles (ITAR / EAR). Defence, aerospace, satellites, some semiconductor and encryption work. These are restricted to a "US Person" — a citizen, lawful permanent resident, or certain protected individuals. An H-1B holder is not a US Person for this purpose.
Security clearance. Eligibility for a clearance generally requires US citizenship. A post saying "must be able to obtain a Secret clearance" is a citizenship requirement in different words.
Some federal and federal-contractor roles. Often citizens-only by statute or contract.

Why this is not discrimination. US law generally prohibits employers from discriminating by citizenship status — but it carves out cases where a law, regulation or government contract requires it. That carve-out is exactly what these postings are using. Arguing the point will not help; filtering these out early will.

Read the pay range — and know when it has to be there

A growing number of US states and cities require employers to publish a salary range in the job post itself. Colorado, California, New York State, Washington, Illinois and others have pay transparency laws, and the details differ by jurisdiction.

What that means in practice:

A range on the post is often a legal requirement tied to the job's location, not generosity.
Remote roles frequently list several ranges by location tier, because the law of the employee's location can apply.
A very wide range usually spans multiple levels. Ask which level the role is at.

Why the number matters more for you than for a US applicant

If this job ever becomes an H-1B petition, the wage is not just compensation — it is part of the filing. USCIS states that where H-1B selection is required, it conducts a weighted selection among registrations, based generally on the highest OEWS wage level that the proffered wage equals or exceeds for the relevant occupation and area.

A higher offered wage relative to the prevailing wage levels for that role and location therefore affects more than your bank balance. Our H-1B cap guide covers how that selection works.

Who actually sponsors: check before you guess

You do not have to infer an employer's sponsorship behaviour from the tone of a job post. The US Department of Labor publishes every certified labor condition application, with the employer's name and the worksite.

From the most recent quarterly file, 55,087 employers had certified H-1B LCAs across 9,178 US cities. You can see the most active of them on our sponsor list, and search the full file at the source.

A certified LCA is not an approved visa. It means the employer filed, and the Department of Labor certified the wage and conditions. It is strong evidence that an employer sponsors at all — which is the question you are trying to answer — but it is not a promise about any individual case.

The boilerplate you can safely skip

Several blocks appear in nearly every US job post and carry no information about your chances:

The EEO statement. "We are an equal opportunity employer…" is standard and legally expected. Its presence says nothing about this role.
Voluntary self-identification. Questions about race, gender, veteran status and disability are collected for federal reporting, kept separate from the hiring decision, and are genuinely optional. "Decline to self-identify" is a normal answer.
"Reasonable accommodation" notices. Standard ADA language.
"This description is not exhaustive." Legal cover, in every post.

Terms that mean something specific

Term	What it actually means
Exempt / Non-exempt	Whether the role is exempt from federal overtime rules. Non-exempt means hourly and overtime-eligible.
W-2 vs 1099	W-2 is employment. 1099 is independent contractor — which does not fit H-1B, since an H-1B requires an employer-employee relationship and a petitioning employer.
Corp-to-corp / C2C	Contracting between companies. Common in IT staffing and frequently not compatible with the visa status a candidate actually holds. Check carefully.
At-will employment	Either side can end employment at any time. Standard in almost every US state, and a real consideration when your status depends on the job.
Contract / contract-to-hire	Fixed term, often through a staffing agency. The agency, not the client, is usually the petitioner.
Relocation assistance	Money for moving. It is not immigration support and does not imply sponsorship.

A five-minute triage, in order

Search the post for "sponsor". One keyword decides most applications. Do this before reading anything else.
Search for "US Person", "citizen" and "clearance". If any appear as a requirement, stop.
Check the worksite location against the pay range, and against where you can actually live.
Check whether the employer appears in DOL's certified LCA data.
Confirm it is W-2 if your plan involves an H-1B petition.
Then read the responsibilities and decide whether you want it.

What we have not published here

We have not listed which specific employers will sponsor you, or quoted current prevailing wage figures. Sponsorship is decided case by case by the employer, and prevailing wage levels are set per occupation and area in DOL's wage data rather than being a single national number. Check the employer's own careers page and the DOL sources below, and take individual advice from an immigration attorney rather than from a job board.
