You also posted this thread on your expired JAA PPL.

If you are wishing to use your JAA license in order to go for a FAA CPL - you will need to be valid and current.
Also - you mention in that other thread that you have flown very little during the past 18 months.
I would urge you to review the FAA regs on getting a FAA CPL - notably 61.127 (Flight Proficiency) and 61.129 (Aeronautical Experience).
Electronic Code of Federal Regulations: You will see that you need 250 hours of flight time comprised of a number of specific requirements.
