Official wording
The term "alien" means any person not a citizen or national of the United States.
Aevamo’s reading
8 CFR 212.1 is the regulation that imposes the visa and documentary requirement on arriving nonimmigrant aliens (chapeau) and that creates and specifies the Visa Waiver Program exemption (i), the Guam-CNMI Visa Waiver Program (paragraph (q)) and the CNMI EVS-TAP (paragraph (r)); it implements INA 212 and Pub. L. 110-229 and is the operative instrument for who may enter Guam and the CNMI without a visa.
INA 101(a)(3) defines an alien as any person not a citizen or national of the United States; the visa requirement in 8 CFR 212.1 applies to each arriving nonimmigrant alien, so a United States citizen or national travelling to Guam is not subject to the visa regime at all.

What this answer covers Limits & assumptions
Work and residence rights are separate from this check. This is the entry rule and the length of stay the instrument grants. It is not a decision about you: the officer at the border decides admission, and we do not evaluate the purpose of your trip, your passport's remaining validity, an onward ticket, funds, insurance or health requirements.
The rule is one instrument covering 2 places, so this answer is the same for Northern Mariana Islands .
