No, you do not need to submit photos with your I-130 petition for your stepdaughter. The primary focus is on providing strong documentary evidence of your relationship, such as birth certificates, marriage certificates, and other relevant documents.

However, including photos can be beneficial as additional supporting evidence. They can visually demonstrate your family relationship and the bond between you and your stepdaughter.

If you decide to include photos, ensure they are clear, recent, and show you and your stepdaughter together in various settings.
