You will still have to sign up with the selective service, doing AOS is not an exemption and is not the same thing as signing up for selective service.
I-485 Instructions and text:
If you are a male at least 18 years old, but not yet 26 years old, and required according to the Military Selective Service Act to register with the Selective Service System,
USCIS will help you register.When your signed application is filed and accepted by USCIS,we will transmit to the Selective Service System your name,current address, Social Security number, date of birth and thedate you filed the application.
This action will enable the Selective Service System to record your registration as of thef iling date of your application.(NOTE: Men 18 through 25 years old who are applying for student financial aid, government employment or jobtraining benefits should register directly with the SelectiveService System or such benefits may be denied. Men canregister at a local post office or on the internet at
http://www.sss.gov).
If USCIS does not accept your application and, if still sorequired, you are responsible to register with the SelectiveService System by using other means, provided you are under26 years of age. If you have already registered, the SelectiveService System will check its records to avoid any duplication.
SELECTIVE SERVICE REGISTRATION. The following applies to you if you are a male at least 18 years old, but not yet 26years old, who is required to register with the Selective Service System:
