Microsoft H1B Sponsorship
Microsoft is the #2 H1B sponsor in the US with 8,000+ LCA filings annually, spanning Azure cloud, Office/Microsoft 365, Xbox, LinkedIn, GitHub, and Bing/AI divisions. Microsoft pays higher base salaries than Amazon — the median H1B base is $172,000 — and uses a quarterly RSU vesting model that provides more predictable compensation than Amazon's 2-year cliff. Microsoft's hybrid work policy (3 days/week in office) is significantly more flexible than Amazon's 2025 5-day RTO mandate. Microsoft's immigration team is one of the most sophisticated in the industry.
Amazon H1B Sponsorship
Amazon is the #1 H1B sponsor in the world with 12,000+ LCA filings annually across AWS, retail technology, Alexa/devices, Prime Video, advertising, and logistics technology. Amazon's SDE (Software Development Engineer) career ladder is one of the most well-known in tech. Amazon's compensation model involves significant sign-on bonuses to offset the 2-year RSU cliff — Year 1 and Year 2 cash compensation is boosted by sign-ons, with RSU vesting heavily weighted to Years 3 and 4 (5%/15%/40%/40% distribution). Amazon's strict 5-day return-to-office policy implemented in 2025 is a major consideration for candidates who prefer flexibility.
Verdict
Amazon sponsors 50% more H1B applications than Microsoft and offers more diverse role types across more divisions. Microsoft pays higher median base salaries, offers hybrid work flexibility, and has quarterly RSU vesting that many engineers prefer over Amazon's 2-year cliff. Both have excellent green card programs. For candidates prioritizing volume of opportunity and maximum H1B paths, Amazon wins. For candidates prioritizing base salary, work flexibility, and product diversity, Microsoft is the better choice.
Frequently Asked Questions
Which company sponsors more H1B — Microsoft or Amazon?
Amazon is the #1 H1B sponsor in the world with 12,000+ annual LCA filings, approximately 50% more than Microsoft's 8,000+. Amazon's scale across AWS, retail, advertising, and logistics creates enormous engineering demand. Microsoft is the #2 H1B sponsor globally.
How does Amazon's RSU cliff affect H1B compensation?
Amazon's RSU vesting schedule is 5% at Year 1, 15% at Year 2, 40% at Year 3, and 40% at Year 4. This means most RSU value comes in Years 3–4. Amazon compensates with large sign-on bonuses (often $50,000–$150,000 over 2 years) and higher Year 1–2 base salaries to bridge the cliff. Microsoft vests RSUs quarterly, providing more predictable income.
Which company is faster at green card sponsorship — Microsoft or Amazon?
Both face identical per-country priority date backlogs — there is no way to accelerate EB-2/EB-3 queues regardless of employer. Both Microsoft and Amazon begin PERM filings as early as possible for H1B employees. The choice of employer does not materially affect green card speed for India-born nationals facing 40–70 year backlogs.
How does Microsoft's remote work policy compare to Amazon's?
Microsoft requires 3 days per week in-office (hybrid) for most roles. Amazon implemented a strict 5-days-per-week return-to-office policy in January 2025, with some exceptions for approved remote roles. For H1B candidates who value work flexibility, Microsoft's hybrid policy is a material advantage.
Which is easier for H1B transfer — Microsoft or Amazon?
Both Microsoft and Amazon accept H1B transfers through portability. Neither company has unusual requirements for transfers. For Amazon, the SDE hiring process (6-round technical interview including system design and behavioral Leadership Principles) is the primary hurdle, not immigration. For Microsoft, the process is similar with coding + design + behavioral rounds.
