He will most likely be able to make it to Guam - there are generally no passport checks, although legally he is still required to carry his passport.
However once he is in Guam, he's in for a world of pain.
Non-US citizens do require a passport to depart Guam, and he WILL be processed by CBP before departing Guam back to the US mainland. At that point his ...
Guam is a pretty interesting case, we do take a lot of things from the Mainland U.S. as sort of examples for how to run things, restaurants included. However, we also have our own unique way of doing certain things as well. As mentioned in the question many of the staff at our food serving establishments here will leave you alone after asking if everything ...
This is only a partial answer, but it's too long for a comment.
There is a separate Guam-CNMI Visa Waiver Program that is open to citizens of certain countries, including Australia. ("CNMI" stands for Commonwealth of the Northern Mariana Islands.) There have been some proposed changes to this program under which applicants for this program will be asked, ...
The restriction on people having visited Iran only applies to the "main" Visa Waiver Program. You're entering under a separate arrangement called the Guam-CNMI Visa Waiver Program, and thus are not affected (and should not apply for an ESTA).
TIMATIC, the database used by airlines, states the following regarding mainland US (for entry under the VWP):

I've had experiences of being really ignored in a restaurant. Waiting 20 minutes for the drink order, then having it go empty and not being refilled for the remainder of the hour and a half visit. ...
Adding another experience to the above question:
Successfully travelled from mainland US (New York) to USVI and back:
Entry to USVI needed only a drivers licence (had a Real ID)
Exit from USVI was the full immigration experience: a CBP window like you have on arrival into USA from an international flight, except it was in the USVI St Thomas airport
According to the Permanent Mission of the Republic of the Marshall Islands to the United Nations,
All visitors must have a passport valid for at least six months, must have sufficient funds for stay, and have an onward/return air or sea ticket.
The original question has already been answered, however I want to share my experience from this past weekend Feb 27th.
we were 3 adults - 2 with expired H1b stamp but valid 797 and one without F-1 stamp but valid 797 + I20.
There was no checking while flying into St. Thomas.
While coming back there were CBP check points similar to immigration counters ...
Answering my own question. I have successfully traveled MA->Puerto Rico->MA and the only document they checked was my US driver's license.
An attorney that works with my employer, however, told me to have my I-797 and a few most recent paystubs with me which I did, but again nobody asked me for them. I also carried my Russian passport (загранпаспорт).
Timatic has this to say about visa exemptions for Australian travellers to Guam:
Nationals of Australia, Brunei Darussalam, Japan, Korea
(Rep.), Malaysia, Nauru, New Zealand, Papua New Guinea,
Russian Fed. and Singapore traveling as tourists or on
business under the Guam-Northern Mariana Isl. Visa Waiver
program for a maximum stay of 45 ...
At the Guam airport, there are authorized airport taxi companies and they are not always available (call taxis can't pick up at the airport). You might want to make advance arrangements through one of the companies found on the airport list.
Most hotels have courtesy vehicles for airport transfers and the hotel hotline telephones are located outside the ...
