Is 91.175 enforced in the USA?

In controlled airspace, the MEA or MVA [radar] is
controlling unless you have a IAP.

In Class G, you can fly under IFR in IMC w/o a clearance,
but you can't climb into or fly sideways into any controlled
airspace w/o first getting a clearance.

You can descend for a landing then, | Chris wrote:

In mountainous areas the minimum is 2,000 feet and most
areas of Class G large enough and high enough in which to
fly IFR are in mountainous areas. The far western
Kansas/eastern Colorado area comes to mind, there are only a
handful of airports within those areas.

Alaska pilots are probably the ones who do this type of
flying on a regular basis.
