Thank you all for your help which you gave. I got an email on Oct 11 for additional evidence. I called my attorney hundred times, but i never reached him. I have paid full amount of money for his service. I guess USCIS send him the letter, but i don't have it. I called USCIS twice, but i still have not the letter. Please give me suggestion for my REF. thanks.
If you want to hire an attorney's service, Please make sure that he is reliable. My attorney is a professor in universiy. He is an American.
