In the Memo or "For" section, write "USCIS I-765" and your SEVIS ID number, found in the in the upper left-hand corner of your I-20. However, you can file many USCIS forms online.To fill out the money order, you will need to "Pay to" U.S. Department of Homeland Security. Which address should we write on the money order? Is it the same as the USCIS address where we will have to send the form? Some USCIS field offices and international immigration offices no longer accept money orders or cashier's checks. They usually cash the check within a week or two after receiving the application. After three weeks or so, you'll get your receipt notice in the mail. We mailed out our package containing my form I-485, I-864 and I-693, along with a copy of the I-130 and I-130A we submitted online. Download and complete a paper Form I-90 (see "How Do I Fill Out Form I-90?" below for general instructions).
