Which CSS client responsibility must be completed within 3 days of Live Date?

• A. Work with TSS to set up CSS
• B. Complete I-9 forms within 3 days of Live Date
• C. Complete WSE upload and submit to TSS
• D. All of the above

Answer: (B)

Form I-9 compliance has a strict 3-day deadline after a new hire’s Live Date. This form verifies identity and work authorization in the U.S., and federal rules require Part 1 to be completed by the start date and Part 2 within 3 business days. That tight window makes it the primary onboarding obligation tied to regulatory compliance for the client.

The other onboarding tasks—such as coordinating with TSS to set up CSS or uploading WSE information to TSS—are important steps, but they do not carry the same mandatory 3-day deadline tied to I-9 verification. They can be addressed within the broader onboarding timeline, whereas failing to complete the I-9 within the specified window can trigger penalties.
