I think that’s right if they enter legally oldbatty, but if arriving from within the Schengen area, people can enter France for 90 days without a visa. Therefore it seems unlikely that if arriving through Italy, Spain, Germany etc that a visa is required, especially since we are told many people throw their documents away, so clearly wouldn’t have a visa. Of course, Britain has never been part of the Schengen area, but none the less, we have never been asked for anything other than a quick check of our passports to enter France. This includes our visit to Europe, including France, during 1973, which was prior to the Schengen area being established anyway. In fact, as students, we travelled through Belgium, Germany, Austria, Switzerland, and France during the summer of 1973, and were asked for nothing more than our passports as we entered each country. I do not believe that economic migrants are asked for a visa in order to enter France, any more than they are asked for one when they succeed in entering the U.K.
