Hello. I am filing an I-130 and I-485 concurrently for my parents who are physically in the U.S. right now. For my I-485, I am attaching an I-864. It says on the website that if I am filing the I-864 within the U.S., I must file under the Department of State and they charge a fee. I followed the website provided on USCIS and DoS but I cannot find any information regarding the fee.
Does anyone know if I need to include a check for the I-864 and if yes, how much would it be, please?
Thank you.
