You're correct, My first PF appt. only had one bar code for I-485 and the most recent one which i received today is for I-765 only. So Normally when everything is filled together, the FP apt. has 2 barcodes? one for 485 and 765?
Correct if you had the correct I-765 form you would of had 2 bar codes on the FP letter, one would be for the I-765 and the other would be for I-485.Just see if you can try to do walkin since you are planning a trip in a few days.
