H1B Sponsorship Status Checker for Job Seekers

Helps international students and visa seekers (CPT/OPT/H1B) identify which employers have sponsored H1B visas in the past, allowing them to filter job searches to sponsorship-friendly companies.

User installs extension -> Extension injects content scripts into job search pages -> User views job listings -> Extension queries local H1B dataset for employer name -> Extension displays H1B sponsorship status badge/info on the job card

Target users: International students on CPT/OPT / H1B visa seekers / Green card applicants / Job seekers requiring visa sponsorship

The extension relies on a local dataset (h1b_20_21_22_23.js) which may not be up-to-date. The analysis assumes the extension does not sync with a live backend for real-time data, but this cannot be fully confirmed without network traffic analysis.
The extension may have a companion website (linkedradar.com) with additional features or paid tiers, but the extension code itself does not reflect this.

Monetization

No paid features detected

The extension appears to be free. There are no references to payment gateways, subscription management, license keys, or feature gating based on payment status. The code contains commented-out references to 'Buy Me a Coffee' and 'Ko-fi' donation links, suggesting the developer accepts voluntary donations but does not enforce paid features. The extension uses a local dataset and does not call external APIs that might require a paid tier.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension does not implement any login mechanism, authentication flow, or account creation UI. It operates by injecting content scripts into job search pages (LinkedIn, Indeed, Glassdoor, Google Jobs) and querying a local dataset (h1b_20_21_22_23.js) for H1B sponsorship information. While the destination services (LinkedIn, etc.) require user login to function, the extension itself does not require a LinkedRadar account or any other login to perform its core function of displaying H1B status badges on job listings.
