I filed my I-485 concurrently with I-765 and I-131 last month for myself and my wife (derivative). My I-765 was returned for improper payment and/or other reasons. It notice said I may be able to refile this online. I am getting conflicting information on whether it is best to file online or by mail. Would the application be not tied to the original application if file online? Are there any downsides to doing it online?
I submitted my I-485 concurrently with I-765 and I-131 and for my wife and son as well on Apr 8 to the Elgin Lockbox. We're filing under EB1 and our date of filing is current (India). While the I-485 and 131 were accepted and I got the receipt numbers for them, I just received the I-765 packet back in the mail with a notice saying fees incorrect or missing. After a lot of checking, I had put in $260 each as we were filing with a pending I-485.
Should I refile online or by mail and what is the correct amount to put?
