Hi, Mom. I have recently emailed KCC to unlock DS-260 some changes and to transfer us to AoS. For the answer they said:
If you are in the United States, you may be eligible to apply to the U.S. Citizenship and Immigration Services (USCIS) for adjustment of status. The option to adjust status may not be available to all applicants. To determine whether you are eligible to adjust your status you must contact USCIS to obtain instructions on how to make an appointment with your local USCIS office.
We are F-1 students. And already have paid our DV fee. Should we contact USCIS in order to make AoS? Or just asking KCC to transfer from CP to AoS is enough? While emailing them we provided current I-20’s and our address is shown in DS-260 where we live more than a year.
You don't need (can't) contact USCIS to initiate the AOS. Just go over the spreadsheet, gather your required documents and send your AOS package(s) to Chicago Lockbox.
