How soon after approval can I start working?

With H-1B, you begin working on the authorized start date, not a fixed period after approval. For cap-subject cases, that date is typically October 1. Here is what to check before you start.

The answer is not a fixed number of days after approval. You may begin working on the authorized start date listed in your H-1B, not simply on the date the petition is approved. That date is what governs, even if the approval notice arrives well in advance.

For petitions subject to the annual cap, the start date is typically the beginning of the fiscal year, October 1. So if your approval notice shows that date, that is when you are authorized to begin your activities, subject to the conditions described in the notice.

There is an extra consideration for those already in the United States under another status or who have requested a change of status: you must wait for that change to take effect, as indicated by USCIS, before starting work. Beginning employment before the authorized date is a violation of immigration rules and can lead to serious complications.

If you have any doubt about your exact start date, rely on what is stated in your approval notice and confirm the details with USCIS or a trusted immigration specialist. Be cautious of any offers that claim to move up that date.
