H-1B Visa Extension Guide: 3-Year vs 1-Year Extensions, Filing, and Timing
H-1B status is granted in 3-year increments up to a 6-year maximum -- but with the right timing, your H-1B can be extended well beyond 6 years. Understanding when to file, which extension type applies, and how to protect yourself during the pending period is critical for every H-1B holder. This guide covers every type of H-1B extension, filing timelines, and what happens when your extension is still pending when your current H-1B expires.
Frequently asked questions
When should I file my H-1B extension?
File your H-1B extension no earlier than 6 months before your current status expires and no later than the day before it expires. USCIS rejects filings more than 6 months early. For regular processing (currently 2-4 months), filing 4-5 months before expiration gives you adequate buffer. For tighter timelines, use premium processing ($2,805 in 2026) for a 15 business-day decision. If your extension is filed before expiration and still pending when your status expires, the 240-day rule automatically extends your work authorization while it is pending.
Can I work while my H-1B extension is pending?
Yes, as long as your extension was filed before your current H-1B status expired. The 240-day rule allows you to continue working for up to 240 days past your I-94 expiration date while the extension is pending. If the extension is denied during this period, you must stop working immediately. If your status expires before the extension is filed, you cannot use the 240-day rule and must not work until the extension is approved.
How many times can I extend my H-1B beyond 6 years?
There is no limit on the number of 1-year or 3-year extensions you can receive beyond 6 years as long as you continue to meet the eligibility requirements (365+ days since PERM or I-140 filing for 1-year extensions; approved I-140 with non-current priority date for 3-year extensions). Many Indian H-1B holders have extended 10-20+ times while waiting for their priority date. Extensions continue until the I-485 is adjudicated and you receive your green card.
