You should not wait until after your July marriage to apply for your Social Security number. If you wait, the Social Security Administration (SSA) will refuse your application because your I-94 expires in August.

The 14-day rule and verification delays

The 14-day refusal rule: The SSA has a strict rule for processing applications. They will refuse to process your application if your immigration documents show your status expires within 14 days. Several people in this exact situation report that they waited until after their wedding to apply, only to have the SSA reject their application because their I-94 was too close to expiring.

The unseen verification risk: Even if you apply slightly before that 14-day window in July, you face another risk. The SSA uses a system called SAVE to verify your immigration status. While initial checks take seconds, if the system requires additional verification, it currently takes about 14 federal workdays. This routine delay could easily push your application into the 14-day rejection window or past your August expiration date entirely.

Updating your name later: You do not need to wait until you are married to get your number. You can apply now. When you legally change your name through marriage, you simply show the SSA your marriage document and your unexpired immigration document. They will issue you a new card with your new name, but your actual nine-digit Social Security number will stay exactly the same.
