If my H-1B visa is expiring soon but my employer has already filed for an extension, can I keep working while waiting for approval?

Yes, you can keep working legally for up to 240 days while USCIS processes the extension.

As long as the extension was filed on time, your work authorization continues.

If USCIS denies the extension, you must stop working immediately.

Keep proof of your filing (receipt notice) to show valid status.
