What is the full H-1B process timeline from registration to October 1 start?

The timeline runs: March (lottery registration) to late March (selection results) to April-June (petition filing) to June-September (USCIS adjudication; premium processing 15 days) to October 1 (earliest status start date). If you travel abroad and need a visa stamp, add consulate appointment time. The earliest you can begin working is October 1 of the fiscal year you were selected.

Can I work while my H-1B petition is pending?

If you are already in H-1B status with another employer and changing employers via H-1B transfer, you can work once the transfer is filed—if you have 180-plus days of prior H-1B status. If this is your first H-1B, you cannot work until it is approved and your status start date arrives. If you are on OPT expiring before October 1, cap-gap rules may extend your work authorization.

What happens at the 6-year H-1B limit?

At the 6-year mark you must stop H-1B status and leave the U.S. for one year—unless: an I-140 was approved before your 6th year allowing 3-year extensions indefinitely, or your PERM was filed at least 365 days before the 6-year mark allowing 1-year extensions. Most tech workers with employer-sponsored green cards in progress trigger these exemptions automatically, but you must track the deadlines.

How long does H-1B visa stamping take at the consulate?

Appointment wait times vary dramatically by post. India-based posts have had backlogs exceeding 12 months in recent years. Emergency appointments and dropbox scheduling have helped some applicants. Third-country stamping in Mexico, Canada, or certain European posts is a common workaround. Check current wait times at travel.state.gov and plan at least 6-12 months in advance if you need to travel internationally.

What is the H-1B green card path?

The standard employer-sponsored green card path involves three stages: PERM labor certification (employer proves no qualified U.S. worker is available), I-140 immigrant petition (employer sponsors you for EB-2 or EB-3), and I-485 adjustment of status or consular processing. For India-born applicants, the EB-2 and EB-3 priority date backlogs are currently 10-20 or more years. EB-1A self-petition or NIW can bypass PERM for qualified individuals.

Can I switch employers during the green card process?

Yes, under AC21 portability. If your I-485 has been pending 180 or more days and your I-140 was approved, you can change to a same or similar job with a new employer by filing Form I-485J (Supplement J). Your priority date and I-140 approval carry forward. This prevents employers from using green card sponsorship as leverage over long-waiting employees.

H-1B Overview

H-1B Process Guide: Complete Timeline from Lottery to Green Card

The H-1B process has more stages than most people realize. This guide maps every step—from March lottery registration through green card sponsorship—with exact timelines and what you control.

By Sumit PatelUpdated May 202615 min read

Stage 1: Electronic Lottery Registration (March)

The H-1B process begins in March each year when USCIS opens the electronic pre-registration window. Your employer pays $215 and submits your name, date of birth, passport number, and education level. The window is typically open March 1-20.

Registration window: early March, approximately 20 days
USCIS lottery runs after window closes; results available in late March via myUSCIS
Selected registrations proceed to full petition filing; unselected registrations are closed
Cap-exempt employers skip the lottery and can file at any time

Stage 2: Petition Filing (April-June)

Selected employers have 90 days from the selection notice to file a complete I-129 petition. Your employer works with immigration counsel to compile the petition package and submit it to the appropriate USCIS service center.

LCA must be certified by DOL before petition is filed (7 business days typically)
Complete I-129 package: petition form, LCA, support letter, education credentials, employer financials
Regular processing: 3-5 months; Premium processing: 15 business days for $2,805
October 1 is the earliest start date for cap-subject H-1B petitions

Stage 3: Visa Stamping (If Outside the U.S.)

An approved I-797 is not a visa. If you are outside the United States or need to reenter, you must obtain an H-1B visa stamp at a U.S. consulate in addition to the USCIS approval.

Schedule a visa appointment at a U.S. embassy or consulate in your home country or a third country
Required documents: DS-160, I-797 approval, valid passport, employer support letter, LCA, pay stubs
Wait times for H-1B visa appointments have ranged from weeks to over a year at some posts—plan early
Once stamped, the visa is valid for multiple entries during its validity period, typically 3 years

Stage 4: Extensions and the 6-Year Cap

Initial H-1B approval is for 3 years, extendable once for another 3 years (6 years total). After 6 years you must leave unless your employer has sponsored you for a green card at a specific stage.

One-year extension: if an I-140 is approved or PERM has been pending for 365 days
Three-year extensions: if I-140 is approved and priority date is not current
These extensions allow H-1B holders to remain indefinitely while waiting for green card availability
Without green card sponsorship or an approved I-140, you face the 6-year hard stop
