At Dallas ASC, there is usually no line
I had my FP taken at the Dallas ASC on year ago. I walked in about
11am, whole thing took about 2 hours though. Procedures include
filling out a form with name/DOB/A# etc. Then having the technician
call you and their taking your prints on a computer. Make sure you
verify all the info in their system, also check if your prints are clear.
