回复：回复：同问。回复：USCIS 来信

My lawyer called USCIS (regular phone number), and got a confirmation number, that after 45 days they will send a letter to me.

Then I received the letter, and it was mentioned in the letter that they are actively processing my case, but need additional review......

It looks like the attorney contacts USCIS may be get more response than I call by myself. But some people call USCIS also get good result.

Do not too worry, good luck!
