It does more than suggest, it states it quite explicitly (for most of us,
neither of the exceptions are likely to apply):

"Unless otherwise authorized by the Administrator, when an instrument
letdown to a civil airport is necessary, each person operating an
aircraft, except a military aircraft of the United States, shall use a
standard instrument approach procedure prescribed for the airport in part
97 of this chapter."

So the next question, which I'll ask on Peter's behalf is...

Since Part 97 only prescribes approaches for airports within the US (and
presumably associated territories), how does an N-registered aircraft ever
fly an IAP in IMC outside the US?
