H4 extension processing

I filed my dependents h4 last week at Texas lockbox with the email notification form and credit card payment option. I still don’t see any response in the email or payment being deducted. UPS package reached. Any idea how long is it taking to accept the documents and deduct fees after receiving documents?

How many days have passed since USCIS received your application. It may take 7 to 21 days before USCIS mail the receipt.

It’s 6 days. I thought they will be processing the Cc transaction the day they receive or the next day.

You will need to wait patiently.
