J & J

Usually takes a week or two, but for some people it's taking a little longer depending where there service area will be for biometrics. Some of the service centers are overly booked so they might just be waiting to book more appointments. I noticed that the Philadelphia area is taking longer then most. If it doesn't arrive within 2-3 weeks I would call USCIS and ask why you haven't gotten a appointment date yet, they will probably put in a service request for you to get a appointment date.

Mine only took about two weeks from the time they got it, I sent mine UPS Standard, but USPS would work just as good too:)I only sent mine UPS because the office is open later. Just so you know you don't need to send in your Canadian passport with ROC, just a copy of front and back of green card, but it would be a good idea to get your passport done before your greencard expires so you have two forms of id that is valid.

When I filed for AOS..I did not get my medical transcribed, I just sent in my medical worksheet they provided me from the medical in Toronto. In the Packet I included a letter stating when I had my medical done and that I have had one done in the last year, Stated where I got it done with the address and phone numbers listed. Also, I printed out the instruction sheet from the I 485 packet regarding the medical and highlighted it..lol Just to be safe I also photocopied my reciept from dr. Seidens office as well as the chest x-ray result he gave back to me. They had no problems with it and I got no RFE's. Some people get there medicals transcribed once in the states before filing for AOS, but I wasn't wanting to spend more money on it if I didn't have to, thought i'd wait for a RFE if that was the case, but it wasn't and we ended up saving some money Best of luck to you on the AOS process!!
Just to add..the form they gave me did not say DS 3025 on it...I forget what it exactly said, but it had all the lists of what shots I had and the doctors signature on the bottom with the checkmark boxes.
