I am a petitioner (US citizen) who filled for my spouse at the Chicago Lockbox. I filled for I-130, I-485 and I-765. I used form G1450 to pay with credit card and authorized the amount of $1760 which was the total amount. They did charge me for it and sent me 3 separate receipts for the 3 cases. They charged me an additional $535 and sent another receipt number which says that they are actively looking in my case. I don't understand why this additional charge.
Someone please let me know what this is and has someone else faced this.
