My wife and stepson have conditional permanent residence cards. 45 days ago we filed I-751 with all of the documents plus a check for $750 plus $85 for my stepson's "biometrics, so a total of $835.00. I included the $85 biometrics because that is the only info I could find online. My stepson is listed on her I-751 in Part 5. and we checked the box that says he is applying with her.
On Friday USCIS mailed the packet back to us saying the wrong fee was enclosed. I looked online at https://www.uscis.gov/g-1055?form=i-751 and there is no indication what the fee now is for a minor child included on the I-751. They both entered the U.S. together and both of their cards expire in 4 days.
I don't know if the fee should be $750 or $1500. I just called USCIS and the representative did not seem to know either and said we need to pay an $85 biometrics fee for each of them so $750+85+85 = $920, but that doesn't seem to make sense since it appears the biometrics fee is now included in the $750 filing fee and is not a separate fee anymore . I am really confused. Am I sending $750, or $,1,500, or the $920 that was recommended by the USCIS agent? Do I just file a separate I-751 form for my stepson and pay the $750 with that? I only have a few days to figure this out before it's deemed a late file. Any help would be appreciated.
