Они просто не могут ехать по программе visa waiver program, по ней граждане ряда стран могут зарегится на сайте консульства США заранее до поездки, заплатить 15 баксов и поехать без визы. Однако при такой поездке в США вам не имеют права платить за что-то, т.е. работать или учиться или оставаться более 90 дней нельзя.
В этом случае нужна виза, а им теперь будет нужна виза в любом случае как россиянам например.
В визе вряд ли откажут если сможешь объяснить зачем посещал Иран:
Visiting the United States Without A Visa
The Visa Waiver Program (VWP) enables citizens of participating countries to travel to the U.S. for tourism or business for 90 days or less without obtaining a U.S. visa.
These citizens can use the Electronic System for Travel Authorization (ESTA). A program managed by the U.S. Customs and Border Protection and the Department of Homeland Security.
As the Netherlands participates in the VWP, most Dutch citizens do not need a visa to travel to the U.S.
Read about the VWP and apply for ESTA on the official website
When can’t I use the VWP (ESTA) and need a visa?
Due to personal circumstances:
you traveled to certain countries (Iran, Iraq, Sudan, Syria, Libya, Somalia, and Yemen on or after March 1, 2011),
you are a dual national of any of the above mentioned countries,
you’ve been denied an ESTA, visa or entry into the United States in the past,
you overstayed on a previous Visa Waiver visit,
you’re not a citizen from a country participating in the VWP program traveling to the U.S.
this includes passengers in transit
passengers not leaving the plane,
if you might otherwise be ineligible for a visa, you are not eligible to use the VWP
Because of different purpose of travel:
business travelers and tourists who wish to stay in the U.S. more than 90 days,
airline crew members,
crew members of commercial, private or maritime vessels,
students,
interns,
exchange visitors,
temporary workers
