The letter itself take about 2 weeks,but if you have an account it will show up in a day.

I'm writing to everyone about any case that you have pending. Please take the time to write your local congressman about your pending USCIS case. We need to put pressure on this system. Look up your local congressman, they should have a web page where you can discuss an issue. Choose immigration or anything close and give a brief description of your case. Include your case #. We need to band together to create change. SPREAD THE WORD! Do this today lets help each other out.

We got our receipt in the online account the same day, arrived in the mail two days after.
