What the code unlocks

H1B data, just ask

The connector gives your assistant direct access to U.S. Department of Labor H-1B and LCA disclosure records: real petitions filed by real employers, not job ads.

◆

Sponsors for your exact role

"Which companies sponsor H-1B for product managers?" answered from real filings, ranked by petition volume.

✓

Verify any job posting

Found a role online? Check whether that company truly sponsors that title before you spend an hour applying.

▲

Entry-level reality check

Every result carries the seniority mix, so you do not chase listings that only ever go to eight-year veterans.

⬤

7.6 million filings

Roughly 198,000 employers, current through the latest published disclosure. Works in both Claude and ChatGPT.

How it works

No commands, no syntax

Once connected, Claude or ChatGPT uses SponsorStats automatically whenever you ask about an employer or a role.

1

Activate your connector

Sign in with Google above and enter your access code. You get a connector URL that is yours.

2

Paste it into Claude or ChatGPT

Add it once as a custom connector. The three steps below walk through it.

3

Start a new chat

Open Claude.ai, the desktop app or ChatGPT and start any conversation.

4

Ask and get real data

Petition counts, salary ranges and seniority breakdowns come back in seconds.

Things you can ask

⭐
"Find companies that sponsor H1B for product managers, check which have roles open now, and tell me which of those openings they actually sponsor."
💬
"Which companies sponsor H1B for data scientists at entry level and are still filing this year?"
💬
"I found a Senior Software Engineer posting at Stripe. Is that a role they actually sponsor?"
💬
"Does Microsoft sponsor H1B visas for software engineers?"
💬
"What is the average H1B salary at Apple for senior roles?"

"Compare Google and Meta H1B filings over the past 3 years."
Powered by DOL public records. Data covers petitions filed with the U.S. Department of Labor. Actual filings, not job postings.

Get started

Connect in 3 steps

Takes under a minute. Activate once with your access code, then use the same URL in Claude or ChatGPT.

1

Get your personal connector URL

Sign in with Google at the top of this page and enter the access code you were given. You get a connector URL that is yours.

2

Paste it into Claude and save

Open Claude's Add custom connector dialog, give it any name, paste your URL from step 1, then click Add.

https://sponsorstats.com/mcp/k/your-key

The plain /mcp address still connects, but returns no data until it carries your key.

3

Start a new chat and ask anything

Claude queries SponsorStats automatically whenever you ask about H1B data. Existing conversations do not pick up a newly added connector, so start a fresh one.

ChatGPT

Using ChatGPT instead?

Same connector, same URL. In ChatGPT go to Settings then Connectors, choose Create or Add custom connector, paste your personal URL from step 1, set authentication to No authentication, and save. Then start a new chat.

Custom connectors need a ChatGPT plan that includes them (Plus, Pro, Business or Enterprise), and on some plans they appear only in developer mode. If you do not see the option, that is a ChatGPT account setting rather than a problem with the URL.

Available tools

What Claude and ChatGPT can look up

Five tools, used automatically based on your question. The first two answer "tell me about this company"; the last three answer "find me companies for this role, and check whether these specific openings are really sponsored".

search_h1b_company

Returns year-by-year H1B petition totals, average salary across all years, and the latest filing year for a given employer. Use this for company-level sponsorship trends.

ParameterTypeRequiredDescription
employer_name string Required Employer to search. Fuzzy and case insensitive, so "Google" matches "GOOGLE LLC".
search_h1b_filings

Searches individual H1B petition filings with optional filters. Returns petition counts and average salaries broken down by wage level (seniority) and by year.

ParameterTypeRequiredDescription
employer_name string Required Employer to search. Fuzzy, case insensitive matching applied automatically.
job_title string Optional Filter by job title. Fuzzy match, so "product manager" matches "Senior Product Manager II".
pw_wage_level I · II · III · IV Optional Filter by prevailing wage level. I is entry level, II qualified, III experienced, IV senior.
year integer Optional Filter to a specific filing year derived from the DOL decision date. Example: 2023.
find_role_sponsors

Starts from a role rather than a company. Returns employers with a filing track record for that job title, ranked by petition volume, with recent activity, filing trend, seniority mix, and how entry friendly the role is.

ParameterTypeRequiredDescription
role_title string Required Role to search. Job posting style titles work, so "Senior Product Manager, Growth" resolves to Product Manager automatically.
wage_level I · II · III · IV Optional Restrict to a seniority band. I is entry level, IV is senior or expert.
active_only boolean Optional Only employers that filed for this role in the most recent 12 months of available data.
min_petitions · limit integer Optional Volume floor, and how many employers to return (default 25, max 50).
check_sponsorship

The verification step. Give it real job postings, company plus title, and it says whether each employer actually sponsors that specific role, not just whether they sponsor at all. Checks up to 25 postings in one pass.

ParameterTypeRequiredDescription
checks array Required Up to 25 {employer_name, job_title} pairs. Paste posting titles verbatim, no cleanup needed.

Each posting comes back with one of five verdicts: core sponsored role (a top 3 title at that employer), regularly sponsored, occasionally sponsored, sponsors but not this role, or no sponsorship record, plus petition count, how the title ranks inside that company, and its entry level share.

resolve_role_titles

Translates a job board title into the titles employers actually write on DOL filings, with petition volume and sponsoring employer counts for each. Used automatically when a title needs disambiguating.

ParameterTypeRequiredDescription
query string Required Title or phrase to resolve. Abbreviations are expanded, so "SWE II" finds Software Engineer and "Senior PM" finds Product Manager.

Troubleshooting

Common issues and fixes

Claude says it can't find the connector, or doesn't use H1B data

After adding the connector you must start a new chat. Existing conversations do not pick up newly added connectors. Also confirm the URL is exactly the one from the top of this page. If you set this up before and used the older /mcp/sse address, delete that connector and re-add it.

It found sponsors but no actual job openings

SponsorStats holds historic DOL filing records. It knows who has sponsored, not what is hiring today. Finding live openings is your assistant's own web search. Make sure web search is enabled in Claude or ChatGPT, then ask it to look up current roles at the companies SponsorStats returned and check those postings back against the connector.

ChatGPT doesn't show a way to add a connector

Custom connectors require a ChatGPT plan that supports them (Plus, Pro, Business or Enterprise), and on some plans they are only visible once developer mode is turned on in settings. This is a ChatGPT account limitation, not a problem with the connector URL.

No data found for a company I know exists

Try a shorter or more generic version of the name. Use Google instead of Google LLC, or Amazon instead of Amazon.com Services LLC. The search is fuzzy but works best with the core company name.

The connector shows as "connected" but Claude never calls it

Make sure your question explicitly mentions H1B, visa sponsorship, or an employer. Claude invokes the connector automatically when the context matches. Try phrasing like "Does [Company] sponsor H1B visas?" or "What are [Company]'s H1B filings?"

I see a connection error

The connector answers each request on its own, so there is no long lived stream to drop. A one off error is usually a cold start on our side and clears on retry. If it persists, remove and re-add the connector at claude.ai, and check the URL has no /sse on the end.

Data looks outdated

SponsorStats is sourced from U.S. Department of Labor public records. The database was last updated with data accessed on October 2, 2025. Filings from after that date are not yet reflected.

Data is U.S. Department of Labor H-1B and LCA disclosure records: real petitions filed, not job ads.
