Summary
You can cross the worry about a mandatory SAVE waiting period off your list. The 15-day delay applies to border entries, not your Change of Status.

The start date and SAVE synchronization
You can apply for your Social Security Number on or after the "valid from" date on your Form I-797 Approval Notice.
The documents do not specify a required number of days you must wait for SAVE database synchronization after a USCIS Change of Status approval. While some sources recommend waiting 15 days, this applies to people entering the United States from abroad, because port of entry records take time to update. Since you changed your status inside the country, this border delay does not apply to you.
Next steps
Follow these steps to apply for your card.
Wait for your H-1B start date
You can apply on or after the "valid from" date on your approval notice.
Gather your original documents
You need to prove your immigration status and work eligibility. Bring your unexpired foreign passport and your I-94 showing your H-1B class of admission.
Apply in person at a Social Security office
As of March 2025, the automated Enumeration Beyond Entry program is suspended. You must attend an in-person appointment to get your number.
Wait for your card in the mail
The Social Security Administration typically issues the card within two weeks of verifying your documents with USCIS. If they cannot immediately verify your status, it may take two additional weeks. If manual verification is required, it can take between four and twelve weeks.
