Selective Service?

I just turned 18 Nov 29th, and I only recently learned about the Selective Service, and the law requiring all 18 year olds to sign up within 30 days of turning 18.
I was wondering if I was required to sign up for it since I'm an undocumented immigrant?

Thanks

All males legal or otherwise are require to register for Select Service at 18 or before your 26 birthday to be eligible for citizenship.

So where would I go to sign up for it, and is there any documents I need to bring with me, such as my passport or Certi. of birth?

Go to your nearest Postal Office and just ask for it fill it and send it. No ID or anything is require, it asks for your social but if you don't have one just leave it blank.

Alright thanks for the info
