Read the letter, it will tell you about biometric, if they will reuse or send you a letter to do biometric. Most cases, they tell you they will reuse because they already have it in their system when you applied for Green card. So yes, it is normal.

hello I just have questions pleasee. I sent my application I-751 last Wednesday and I still did not receive anything yet and no update in my account you know how long it’s gonna take to show in my account or just receive receipt from them

I’m having issues with accessing my online account but I don’t know how long it takes to show up in the account but it took about 1 week for them to cash my check and 2 weeks to receive the extension notice in the mail

@Joy Jin they dont usually ask for biometrics for an extension.
