Answer 1

Https://www.sss.gov/Registration-Info/Who-Registration

Under current law, all male U.S. citizens between 18–25 years are required to register with Selective Service within 30 days of their 18th birthday. In addition, non-U.S.-citizenmen between the ages of 18 and 25 (inclusive) living in the United States must register.

I linked a site that may be helpful. But that is also what I have to say. Hope that helps! :)
