What is ‘I-9 verification’?

I-9 verification is the mandatory process that every employer in the United States must complete to confirm that a newly hired worker is legally authorized to work in the country. It applies to all hires, including those with an H-1B visa.

The name comes from the I-9 form, which is completed at the start of employment. The process has, in general terms, two parts:

• the worker fills out the form and presents documents proving identity and work authorization;
• the employer reviews those documents, verifying that they are among those accepted under immigration rules.

For H-1B workers, the employer follows the same rules that apply to any hire: the visa provides the work authorization, and the I-9 is the step that records and confirms it at the time of onboarding.

Keeping this verification in order protects both the employee and the employer, preventing legal complications. If you have questions about accepted documents or deadlines, check the official USCIS resources or consult a specialist.
