seems like USCIS is not interested in waiving fees for bIOMETRICS. I filed i-131 AND PAY THE $305 FEE BUT not the $80 biometric fee cos I filed for FEE WAIVER request. everyhting was done properly. after 2-3 weeks, got a letter stating you failed to pay the biometric fee and that I have about 3 months to pay that or get the application denied! They have given no response to my fee waiver request, nothing like , request deined or not proved! strange!
